The following individual card rulings have been compiled from the archived UDE Gameplay FAQ database [REF] and the Konami Card Rulings documents [CRMS, RGBT, ANPR, SOVR, ABPF, HA01, SDMM]. Notable cards have streamlined rulings and additional information cross-referenced against Pojo / Duelistgroundz.

UFO TURTLE

• If you attack with your "UFO Turtle" and it is destroyed as a result of battle, you may attack with the monster Special Summoned by "UFO Turtle" before entering Main Phase 2.

• Since the Special Summoning occurs during the Damage Step, "Torrential Tribute", etc. cannot be used.

UFOROID

• If “UFOroid” attacks an Attack Position “Pyramid Turtle”, first the turn player decides whether to activate the effect of “UFOroid” or not, and if he does, it will be Chain Link 1. If he doesn’t, the opponent has a chance to activate “Pyramid Turtle’s” effect and be Chain Link 1. If he does, it is too late for the turn player to decide to activate “UFOroid’s” effect.
• If you do not choose to Special Summon a Machine, this card’s effect will not activate or start a chain.

UFOROID FIGHTER

• If “UFOroid Fighter” is Special Summoned with “Cyber-Stein” or “Metamorphosis”, its original ATK & DEF will be zero.

• If “UFOroid Fighter” is on the field, and then “Skill Drain” is activated, the original ATK & DEF will be zero, and will remain zero even if “Skill Drain” is destroyed or negated.

• The Union Monster you equip to your "Union Rider" is actually placed in your Spell & Trap Card Zone, so it counts for you for "Mage Power", etc.
• You must have a Spell & Trap Card Zone space vacant to activate your "Union Rider"'s effect.

When "Unstable Evolution" is negated or removed from the field, "Fusilier Dragon, the Dual-Mode Beast's" ATK becomes halved to 1400.
• The monster equipped with "Unstable Evolution" is not destroyed by "Overworked", because "Unstable Evolution" changes the monster original ATK to a new value. The monster will be destroyed if another effect increases its ATK.

URGENT SYNTHESIS

• Returning 1 “Iron Core of Koa’ki Meiru” to the Deck is a cost to activate “Urgent Synthesis.” The effect does not target. You cannot activate “Urgent Synthesis” while “Transmigration Break” is active, as you cannot pay the cost to return “Iron Core of Koa’ki Meiru” to the Deck.

• If the number of monsters you control changes due to an effect chained to “Urgent Tuning”, and you do not have a Synchro Monster of a Level you could Summon when “Urgent Tuning” resolves, you must show your Extra Deck to your opponent to prove that you cannot Summon a monster. You do not have to show your Extra Deck to your opponent if you would not be able to Synchro Summon at all when “Urgent Tuning” resolves. (Because you control only 1 monster, or control only Tuner monsters, etc.)
• You can use monsters that are not affected by Trap Cards, like “Elemental Hero Wildheart” as Synchro Material Monsters for “Urgent Tuning”.

However, if "Call of the Mummy" or "Valhalla, Hall of the Fallen" is already face-up on the field and its effect is activated, then "Royal Oppression" may be chained to negate the effect and destroy it.

VALKYRION THE MAGNA WARRIOR

• You can Tribute the three monsters required to Special Summon this card from your hand, the field, or any combination of the two.
• You can only Special Summon this card through its own effect during your Main Phase 1 or 2. You can also only use its effect to Special Summon the Magnet Warriors during your Main Phase 1 or 2.

VAMPIRE LORD

• Your Vampire Lord will only be Special Summoned by his own effect when destroyed and sent to the Graveyard by a card effect that your opponent controls, not by your own card effects or as a result of battle.
• Vampire Lord will only return to play with his effect when the owner controls it, because Vampire Lord must be “destroyed and sent to YOUR Graveyard”.
• When your opponent takes control of your Vampire Lord, and it inflicts Battle Damage to your Life Points, then the first effect of Vampire Lord is activated. But the second effect will not be activated if Vampire Lord is destroyed and sent to the Graveyard while your opponent controls him.
• If you Summon "Vampire Lord" (except by its effect) and he is destroyed by your opponent's "Horn of Heaven" or "Solemn Judgment", "Vampire Lord" will be Special Summoned in your next Standby Phase. When it is Special Summoned by its own effect “Horn of Heaven” or “Solemn Judgment” cannot be activated, because it is being Summoned by its own Trigger Effect, not by a built-in “this is how you Summon this monster” effect.
• When Vampire Lord is destroyed (by a card effect) while in your hand, in your Deck, or on the field, he will be Special Summoned in your next Standby Phase.
• When Vampire Lord is Tributed (including by your opponent with Soul Exchange), or when he is “sent to the Graveyard”, he will not be Special Summoned by his own effect because he was not “destroyed”.
• If Vampire Lord is supposed to be Special Summoned, but your Standby Phase is skipped with Solomon’s Lawbook or Gamble, Vampire Lord won’t be Special Summoned, not even on the following Standby Phase.
• If Vampire Lord is supposed to be Special Summoned, but gets returned to your hand or Deck instead, he won’t be Special Summoned.
• If Vampire Lord is destroyed and sent to the Graveyard by your opponent’s card effect, but returns to the field that same turn and is then destroyed in a manner that would not allow him to be Special Summoned, then he is not Special Summoned.
• You can keep Special Summoning Vampire Lord as long as each time he is destroyed by your opponent’s card effect.
• Vampire Lord is Special Summoned to your side of the field; you cannot Special Summon him to your opponent’s side of the field.
• When you have your Vampire Lord in play, Special Summoned by your Premature Burial or Call of the Haunted, and your opponent destroys Premature Burial or Call of the Haunted with Mystical Space Typhoon, the Vampire Lord won’t be Special Summoned because it was destroyed by your card effect, not by your opponent’s.
• If your opponent controls your Vampire Lord with Autonomous Action Unit, and Autonomous Action Unit is destroyed, Vampire Lord won’t be Special Summoned because the owner did not control him.
• When you Special Summon Vampire Lord with his effect, your opponent can negate the Special Summon with "Royal Oppression". Since the effect of "Vampire Lord" activates in the Graveyard, "Vampire Lord" is never moved from the Graveyard, so it is never destroyed. (A card already in the Graveyard cannot be destroyed). Because it is not destroyed, its effect to Special Summon itself does not activate again.
• If Vampire Lord is destroyed while equipped to Relinquished, he won’t be Special Summoned, no matter who controls him or who destroyed him.
• If Vampire Lord is destroyed while face-down by Sasuke Samurai, Vampire Lord will be Special Summoned by his effect.
• Vampire Lord can be Special Summoned by his own effect even while Necrovalley is in play.
• When Vampire Lord is Summoned while your opponent’s Rivalry of Warlords is active and your only monsters are non-Zombie, Vampire Lord is destroyed, but is not considered destroyed by Rivalry of Warlords’ effect and won’t be Special Summoned.
• When your opponent doesn’t have the type of card that you declared for Vampire Lord, the effect of Vampire Lord disappears but you get to look at your opponent’s Deck to confirm it.
• It is the controller of Vampire Lord, not necessarily the owner, that names a card type.
• When you name “Spell” for Vampire Lord, it includes Normal, Quick-Play, Field, Ritual, Continuous, and Equip Spell Cards, and the same is true for Traps.
• Card effects like Penguin Knight, Sword of Deep-Seated, and Cockroach Knight will activate their effects when sent to the Graveyard by Vampire Lord’s effect.

VAMPIRE'S CURSE

• You pay 500 Life Points when "Vampire's Curse" is sent to the Graveyard. Paying 500 Life Points is a cost.
• The effect that increases "Vampire's Curse's" ATK starts a Chain when it is Special Summoned by its effect.
• "Vampire's Curse" is not Special Summoned with its effect if it is removed from play.

VAN'DALGYON THE DARK DRAGON LORD
(1) After a Counter Trap Card you control negates the activation of an opponent's card(s) or effect(s), you can Special Summon this card from your hand. (2) Then activate the appropriate effects, based on the type of cards negated:
• Spell: Inflict 1500 damage to your opponent.
• Trap: Select and destroy 1 card your opponent controls.
• Effect Monster: Select 1 monster in your Graveyard and Special Summon it.

• The (1) optional Trigger Effect activates & resolves in the hand.
  • This effect cannot be activated during the Damage Step [REF].
  • This effect activates AFTER a Chain resolves in which an opponent's card / effect was negated (as Chain Link 1+) by your Counter Trap Card (even if you drew this card during the Chain).
  • If you have 2 or more "Van'Dalgyon the Dark Dragon Lord" (or "Voltanis the Adjudicator") in your hand when your Counter Trap Card negates your opponent's effect, you can only activate the effect of 1 "Van'Dalgyon the Dark Dragon Lord", even if you negate multiple card effects.
  • If your opponent discards 1 Spell Card for "Magic Drain", you cannot activate this effect.
• The (2) mandatory Trigger Effect activates & resolves on the field.
  • If you activate multiple Counter Trap Cards in a single Chain, the last one to resolve is applied.
    • Example: Your opponent activates "Card Destruction". You chain "Magic Jammer". Your opponent chains "Seven Tools of the Bandit". You chain "Curse of Royal". When the Chain resolves, "Magic Jammer" is your last Counter Trap Card that resolves and negates your opponent's "Pot of Greed", so you will be able to Special Summon "Van'Dalgyon the Dark Dragon Lord" and activate its "inflict 1500 damage" effect.
  • If a Spell Card is negated, this effect inflicts Effect Damage.
  • If a Trap Card is negated, this effect targets a (face-up / face-down) card your opponent controls.
  • If a Monster Effect is negated, this effect targets a monster in the Graveyard. It is negated by "Necrovalley".
• VS. "Vanity's Call": if this card negates multiple card effects controlled by your opponent, when you Special Summon "Van'Dalgyon the Dark Dragon Lord" you will activate each effect appropriate effect.
  • Example: "Vanity's Call" negates your opponent's "Destiny Draw" and "Dark Bribe". Van'Dalgyon you will activate its "inflict 1500 damage" and "destroy 1 card" effects when Summoned. You can choose to have "inflict 1500 damage" be Chain Link 1 and "destroy 1 card" be Chain Link 2, or vice-versa.

VANGUARD OF THE DRAGON

• Sending 1 Dragon to the Graveyard is a cost to activate this monster’s effect.
• “Vanguard of the Dragon’s” effect that Special Summons a monster is a targeted effect.
• You can activate “Vanguard of the Dragon’s” ATK increase multiple times in the same turn.
• The ATK increase lasts as long as “Vanguard of the Dragon” remains face-up on the field.

VANITY'S CALL

• Unless the activation of a card can be negated, the effect will not be negated either. So an effect like “Stumbling” on a chain will not be negated nor destroyed by “Vanity’s Call”.

VANITY'S FIEND
(C) This card cannot be Special Summoned. (1) While this card is on the field, neither player can Special Summon monsters.

  • Cards / Effects that perform Special Summons (ex: "Scapegoat") cannot be activated.
  • Mandatory effects (like “Gravekeeper's Spy”) still activate, but you do not Special Summon.

VANITY'S RULER

• Effects that would make both players Special Summon, like “The Shallow Grave”, cannot be activated while “Vanity’s Ruler” is in play. Effects that must activate, like “Spear Cretin”, will still activate, but the effect disappears.

VARIETY COMES OUT

• Returning the Synchro Monster to the Extra Deck is a cost.
• You target the Tuner monster(s) you wish to Summon.If one of the targets is no longer in the Graveyard, you still Special Summon the rest of them.
• If the Level of the Synchro Monster you returned was being modified, you refer to the modified Level in choosing targets.

VEHICROID CONNECTION ZONE

• If the Special Summoned “Vehicroid” monster is flipped face-down then the effect of “Vehicroid Connection Zone” is no longer applied.

VEIL OF DARKNESS

• Reveal the drawn DARK monster when you activate the effect of "Veil of Darkness". That DARK monster is sent to the Graveyard when the effect is resolved.
• You can activate the effect of "Veil of Darkness" when you draw a DARK monster with a card effect during your Draw Phase.
• When you draw a DARK monster with the effect of "Veil of Darkness", you can reveal the drawn DARK monster to activate the effect of "Veil of Darkness'" again.
• "Veil of Darkness'" effect can only be activated during your own Draw Phase. This effect starts a chain.
• Drawing is optional. You can choose to send the DARK monster to the Graveyard, and then choose to not draw.
• If the DARK monster is removed from play by "Macro Cosmos", then you cannot draw.
• If you control two copies of "Veil of Darkness", both of them can be activated when you draw a DARK monster. However, the first copy sends the DARK monster to the Graveyard, so the second copy cannot send it to the Graveyard, so you cannot draw from the second copy.
• If, during your Draw Phase, you draw a DARK monster because of "Reload", you can activate "Veil of Darkness". If you draw a DARK monster because of "Veil of Darkness, you can activate the effect of "Veil of Darkness" again.
• The effect of a monster like "Sillva, Warlord of Dark World" only activates when it is "discarded to the Graveyard" from the hand by a card effect. The effects of "Hand Destruction" and "Veil of Darkness" "send to the Graveyard" the cards - this is not the same as "discard to the Graveyard". Thus, if a monster like "Sillva, Warlord of Dark World" is sent to the Graveyard by these effects, then you cannot activate its effect.

VENGEFUL SERVANT

• The effect of “Vengeful Servant” starts a chain when control of the monster switches.
• If a Continuous Effect would destroy the equipped monster first (example: an equipped “Thunder Nyan Nyan” switches sides and is destroyed immediately), then the effect of “Vengeful Servant” does not activate and it does not inflict damage.
• If “Remove Brainwashing” is active and a monster equipped with “Vengeful Servant” switches sides, that monster immediately switches back to the original controller.
• The effect of “Vengeful Servant” then starts a chain (and only activates once, in this case) and the original controller of the monster takes damage.

VENGEFUL SHINOBI

• "Vengeful Shinobi's" effect is a Trigger Effect.
• If an effect is Chained to "Vengeful Shinobi's" effect, and changes it to Defense Position or removes it from the field, you still draw a card.

WABOKU

• "Waboku" makes Battle Damage dealt by your opponent's monsters to your monsters and to your Life Points become zero.
• "Waboku" applies to ALL of the monsters on that player's side of the field for the entire turn.
• To illustrate how "Waboku" works, here are some scenarios and their results:
• SCENARIO 1: Player A's "Mega Thunderball" attacks Player B's "Mega Thunderball", and Player B activates "Waboku". RESULT: Player A's (attacking) "Mega Thunderball" is destroyed. Player B's "Mega Thunderball" (with equal ATK) is NOT destroyed.
• SCENARIO 2: Player A activates "Waboku". Player A's "Mega Thunderball" then attacks Player B's "Mega Thunderball". RESULT: Player B's "Mega Thunderball" is destroyed. Player A's (attacking) "Mega Thunderball" is NOT destroyed. So you can use "Waboku" "offensively" when attacking an equal ATK monster.
• SCENARIO 3: Player A activates "Waboku". Player A's "Blue-Eyes White Dragon" then attacks Player B's "Sanga of the Thunder". Player B uses "Sanga of the Thunder"'s effect (during the Damage Step). RESULT: Player A's "Blue-Eyes White Dragon" (ATK 0) is not destroyed, nor does Player A lose any Life Points, because of Player A's "Waboku".
• SCENARIO 4: Player A's "Mega Thunderball" attacks Player B's "Mega Thunderball". Player B activates "Fairy Box" or "Mirror Wall". Player A activates "Waboku". RESULT: Player A's "Mega Thunderball" (with reduced ATK) is not destroyed, nor does Player A lose any life points, because of Player A's "Waboku". But because Player A's "Mega Thunderball" had reduced ATK, Player B's "Mega Thunderball" is not destroyed either.

WALL OF ILLUSION

• If the monster battling with "Wall of Illusion" is somehow destroyed during Damage Calculation, it is sent to the Graveyard and NOT returned to the owner’s hand.

WALL OF IVY

• “Ivy Token’s” effect to inflict damage does not start a Chain.
• If the "Ivy Token" is destroyed by a card effect, inflict damage after the effect resolves. If the "Ivy Token" is destroyed by battle, inflict damage at the end of the Damage Step, when monsters destroyed by battle are sent to the Graveyard.
• If "Remove Brainwashing" or "Owner's Seal" is activated, control of the "Ivy Token" is shifted to the player that activated "Wall of Ivy's" effect.

WALL OF REVEALING LIGHT

• Paying Life Points for "Wall of Revealing Light" is a cost.
• If "Wall of Revealing Light"'s effect is negated by "Royal Decree" or "Jinzo", and then that card is destroyed, the effect of "Wall of Revealing Light" is re-applied.
• The monsters prevented from attacking by "Wall of Revealing Light"'s effect cannot even "declare" an attack.
• You can chain "Last Turn" to your activation of "Wall of Revealing Light" as long as "Last Turn"'s conditions are then correct (1000 or less Life Points).
• You can activate "Wall of Revealing Light" during the Battle Step after an attack has been declared. If the monster's ATK is lower than the Life Points you paid, the attack stops (does not enter the Damage Step).

WATAPON

• If you draw "Watapon" by the effect of "Graceful Charity" you can Special Summon it to the field after you discard the two cards for "Graceful Charity".
• "Painful Choice", "Graceful Charity", and "Witch of the Black Forest" are all examples of the types of effects that will activate the effect of "Watapon".

WATER DRAGON

• When this card on the field is destroyed and sent to the Graveyard, its Optional Trigger Effect activates. You must have at least 2 “Hydrogeddon” and 1 “Oxygeddon” in your Graveyard to target, otherwise the effect will not activate. If you have 3 correct targets, the opponent can chain “Disappear” to remove from play 1 of the monsters, but the other 2 will still be Special Summoned.
• The effect of “Water Dragon” that activates when it is destroyed targets 2 “Hydrogeddon” and 1 “Oxygeddon” in the Graveyard.
• If you do not have 3 open Monster Card Zones after “Water Dragon” is sent to the Graveyard, you cannot activate its effect.
• If “Water Dragon” was face-down on the field when it was destroyed and sent to the Graveyard, you can still activate its effect.
• Missing the Timing: If “Water Dragon” is destroyed by an effect in the middle of a chain, you will miss the timing and cannot Special Summon the 3 monsters from your Graveyard.
• While “Water Dragon” is face-up on the field, either player can activate an effect to increase the ATK of a FIRE or Pyro-Type monster, but the Continuous Effect of “Water Dragon” will change it back to 0.

WATER HAZARD

• The effect to Special Summon a monster starts a Chain.
• If the effect of “Water Hazard” activates, and an effect is Chained that gives you to control of a monster, the effect of “Water Hazard” will not be applied.

WAVE-MOTION CANNON
(1) During your Main Phase, you can send this card to the Graveyard to inflict 1000 damage to your opponent for each of your Standby Phases that have passed since this card was activated.

• The (1) Ignition-like Effect activates & resolves on the field.
  • Sending "Wave-Motion Cannon" to the Graveyard is a cost.
  • No Counters are involved in this card's effect. You simply count your own Standby Phase.
  • This effect cannot be negated by "Magic Jammer", etc. Your opponent can chain "Magic Jammer" when you first activate "Wave-Motion Cannon" (when you place it face-up on the field).
  • If "Imperial Order" is active, count Standby Phases as normal for "Wave-Motion Cannon".
  • You can activate "Wave-Motion Cannon" (place it face-up on the field) and send it to the Graveyard during the same turn, but it will not do any damage.
  • If "Solomon's Lawbook" skips your Standby Phase, or the turn is skipped with "Gamble", increase the count for "Wave-Motion Cannon" anyway. "Pyro Clock of Destiny" will not increase the count.

WEAPON CHANGE

• "Weapon Change" applies to the current ATK & DEF.
• "Weapon Change"'s effect targets 1 monster. You select the monster when you activate "Weapon Change"'s effect.
• If you use "Weapon Change"'s effect on "Freed the Matchless General", "Weapon Change" is destroyed.
• Even if the selected monster's Type is changed by "DNA Surgery", the monster receives the effect of "Weapon Change".
• If "Weapon Change" is removed from the field by "Giant Trunade" or "Emergency Provisions", "Weapon Change"'s effect is not applied.
• If "Imperial Order" is activated after "Weapon Change", "Weapon Change"'s effect is negated, but if "Imperial Order" is destroyed, then "Weapon Change"'s effect is re-applied.
• If you switch a monster's ATK/DEF with "Weapon Change", and then apply a new modifier, apply it to the switched ATK/DEF. Then, after "Weapon Change"'s effect ceases, re-apply the modifier to the reverted ATK/DEF once again.
• If you use "Weapon Change" to make "Gear Golem" into a 2200/800 monster, then use "Limiter Removal" to make it 4400/800, then destroy "Weapon Change", "Gear Golem" is 800/4400.

WEEPING IDOL

• This is an Ignition Effect that activates in the hand. Removing from play 1 Tuner monster in your Graveyard is a cost.

WHIRLWIND WEASEL

• After “Whirlwind Weasel’s” Flip Effect has resolved, the effects of already face-up Spell and Trap Cards, like “Ultimate Offering”, can still be activated.
• The effects of Spell and Trap Cards that activate when the card is destroyed, such as “Blast with Chain” or “Ojamagic” will also still be activated. (In other words, you cannot activate a card, but you can activate an effect.)

WHITE MAGICIAN PIKERU

• Monster tokens and face-down monsters are included for "White Magician Pikeru"'s effect.
• Even if there are many monsters, "White Magician Pikeru" increases Life Points by 1 lump sum.
• "White Magician Pikeru" includes itself in its effect.
• If you resolve "White Magician Pikeru"'s effect and then in the same Standby Phase the number of monsters on the field increases, you don't get additional Life Points.

WHITE NIGHT DRAGON
(1) Negate the activation of any Spell or Trap Card that targets this card, and destroy that card. (2) When a face-up monster you control is selected as an attack target, you can send 1 Spell or Trap Card you control to the Graveyard to change the target to this card.

• The (1) Quick Effect activates & resolves on the field.
  • This effect can be activated on either players turn, and even in the Damage Step.
  • This effect can be activated more than once in a Chain.
• The (2)  optional Trigger Effect activates & resolves on the field.
  • Sending a Spell or Trap Card to the Graveyard is a cost.
  • This effect does not target.
  • If you control your opponent’s monster with “Snatch Steal” while you have “White Night Dragon” in play and your opponent attacks the equipped monster, if you send “Snatch Steal” to the Graveyard to change the attack target no replay occurs.
  • If this effect is negated by “Skill Drain,” a replay occurs.

WHITE POTAN

• If “White Potan” becomes a Tuner, it cannot be destroyed by battle.
• If a monster being treated as a Tuner is destroyed by battle and sent to the Graveyard, it is not considered a Tuner in the Graveyard, and the effect of “White Potan” to inflict damage will not activate.

WICKED REBIRTH

• Paying 800 Life Points is a cost to activate “Wicked Rebirth.”
• This card targets the Synchro Monster, both when you activate this card and while the monster is on the field.
• If “Royal Decree” becomes active while “Wicked Rebirth” is active, the Synchro Monster’s effect is restored, and it can attack this turn.
• If you Special Summon “Stardust Dragon” with “Wicked Rebirth,” you can Tribute “Stardust Dragon” for its effect. After it is Tributed, “Stardust Dragon” is no longer targeted by “Wicked Rebirth.” Therefore its effect is restored and applied normally (so it negates an effect and is Special Summoned back to the field during the End Phase).
• The Special Summon of “Wicked Rebirth” is not a Synchro Summon, so it cannot be used to Special Summon monsters like “Trident Dragion.”

WICKED-BREAKING FLAMBERGE - BAOU

• Sending 1 card to the Graveyard is a cost. This is not "discarding" so it doesn't trigger "Forced Requisition", and you can pay the cost even if "Goblin of Greed" is in play.
• If a monster equipped with "Wicked-Breaking Flamberge - Baou" attacks and destroys "Amazoness Fighter" or "Amazoness Swordswoman", their effects are not negated because they happen during damage calculation, before they are determined to have been destroyed.

WIDESPREAD DUD

• “Widespread Dud” targets the 2 face-up monsters. The effect to destroy the targeted monsters does not start a Chain.
• If “Enemy Controller” is Chained to “Widespread Dud” and shifts one of the targeted monsters to face-up Defense Position, “Widespread Dud” will still resolve normally.
• Even if one of the targeted monsters is changed to Defense Position after “Widespread Dud” resolves it will still be affected by “Widespread Dud.”
• If “Book of Moon” is Chained to “Widespread Dud” and flips one of the targeted monsters face-down, only the other one will continue to be targeted.
• After “Widespread Dud” resolves, when one of the targeted monsters is removed from the field “Widespread Dud” is destroyed and the other monster is destroyed. 

WILD FIRE

• You cannot activate this card if you do not control a “Blaze Accelerator” card.
• You cannot activate this card if there are no monsters on the field.
• If there are no monsters on the field when “Wild Fire” resolves, you cannot Special Summon any Tokens, but you can declare an attack that turn.
• You cannot activate "Wild Fire" if you are prevented from Special Summoning monsters, due to an effect like "Scapegoat".
• If you activate "Wild Fire" the effect that you cannot declare an attack affects you, the player, so even a monster that is unaffected by the effects of Spell Cards like "Horus the Black Flame Dragon LV6" cannot attack.
• You can activate "Royal Oppression" in a chain to "Wild Fire".
• "Blaze Accelerator" is destroyed when "Wild Fire" resolves. If an effect is chained that removes "Blaze Accelerator" from the field, "Wild Fire's" effect disappears and you can attack that turn.

WILD NATURE'S RELEASE

• When you increase the ATK of a monster with "Wild Nature's Release", then apply another modifier, the new modifier is applied to the current ATK points.
• If "Ojama Yellow" is equipped with "Axe of Despair" (1000 ATK, 1000 DEF), if "Wild Nature's Release" is activated then it increases "Ojama Yellow" to 2000 ATK, 1000 DEF. If "Axe of Despair" is then destroyed, "Ojama Yellow" remains 2000 ATK, 1000 DEF.
• If a monster is affected by "Wild Nature's Release", and its Type is then changed with "DNA Surgery", the effect of "Wild Nature's Release" is not negated and the monster is still destroyed during the End Phase.
• If you activate multiple "Wild Nature's Releases", the effects are cumulative.

WINGED KURIBOH

• If “Winged Kuriboh” is destroyed as a result of battle, its effect will not reduce the Battle Damage its owner takes from that battle, because its effect doesn’t activate until later, when it’s sent to the Graveyard. (And damage calculation has already happened by then.)
• If “Winged Kuriboh” is destroyed and sent to the Graveyard, its effect activates and applies for the rest of the turn, even if “Winged Kuriboh” is removed from play with “Disappear”, or shuffled back into the Deck with “Fiber Jar”.
• Because the effect of “Winged Kuriboh” activates in the Graveyard, it will not be negated by “Skill Drain” but it will be negated by “The End of Anubis”.
• Because the effect of “Winged Kuriboh” activates in the Graveyard, it is the original owner that will get the effect. So if the opponent took control with “Change of Heart” or “Snatch Steal”, if it is destroyed then it goes to the original owner’s Graveyard and they get the effect.
• When “Winged Kuriboh” is destroyed and sent to the Graveyard, the activation of its effect can be chained to.
• After the effect of “Winged Kuriboh” resolves, the application of the effect (making Battle Damage zero) does not start a chain and cannot be chained to.
• If “Winged Kuriboh” is treated as an Equip Card (like if it’s equipped to “Relinquished”) and it’s destroyed and sent to the Graveyard, its effect still activates.
• If your opponent takes control of your “Winged Kuriboh” and when it tries to return to your control you have no open Monster Card Zones, “Winged Kuriboh” is destroyed and sent to the Graveyard, and its effect activates.

WINGED KURIBOH LV10

• “Winged Kuriboh LV10's” effect is a Quick Effect. You cannot activate this effect during the Damage Step.
• The Quick Effect of “Winged Kuriboh LV10”can be chained to. You can chain “Barrel Behind the Door” or “My Body as a Shield” to the effect.
• Tributing “Winged Kuriboh LV10” is a cost to activate its effect.
• The “combined original ATK” of the destroyed monsters is calculated after the monsters are destroyed and are no longer on the field. So a destroyed “King of the Skull Servants” would add 0 damage to this effect, and a destroyed “Fusilier Dragon – the Dual Mode Beast” that was Summoned without Tribute would add 2800 damage.
• You cannot activate “Level Up!” to send “Winged Kuriboh LV10” to the Graveyard because it does not have a monster’s name in its text.
• You may return “Winged Kuriboh LV10” from your Graveyard to your Deck with the effect of “The Graveyard in the Fourth Dimension”.
• If an opponent’s monster cannot be destroyed by the effect of “Winged Kuriboh LV10”, no damage is dealt for that monster’s ATK. For example, if “Master Monk” targeted by “Lone Wolf” is on the field, it is unaffected by monster effects, so it will not be destroyed and its 1900 original ATK points will not be inflicted to its controller.
• You can activate the effect of “Winged Kuriboh LV10” if “Skill Drain” is on the field, and its effect will resolve normally and not be negated, because it is no longer a face-up monster on the field.

WINGED MINION

• If the Fiend-Type monster that received the ATK and DEF increase from this card’s effect is flipped face-down, the effect is reset and the ATK and DEF return to the original amounts.
• You may Tribute two "Winged Minions" to increase the ATK and DEF of a Fiend-Type monster by 1400 points.
• If the Fiend-Type monster that was selected for this card’s effect is changed into a different Type, by the effect of "DNA Surgery" for example, it retains the 700 point ATK and DEF increase.

WINGED RHYNOS

• This effect cannot be chained to the activation of the effect of an already face-up Continuous Trap Card, like "Ultimate Offering". It can only be chained when a Trap Card itself is activated (ie., flipped face-up).
• This effect is a Spell Speed 2 Quick Effect. Therefore, it cannot be chained to the activation of a Counter Trap Card.
• This effect can be activated multiple times in the same chain, but only once for each Trap Card activated.

WITCH DOCTOR OF SPARTA

• If 2 or more monsters are Special Summoned by the same effect, “Witch Doctor of Sparta’s” effect will only activate once and it will inflict 500 points of damage.

WITCH OF THE BLACK FOREST

• You must show your opponent the monster you select from your Deck for this card’s effect. If you have no eligible monsters, your opponent gets to see your Deck to verify.
• The effect of "Witch of the Black Forest" only activates when she is sent from the field to the Graveyard, not from your hand or Deck, and not if she is removed from play.
• If the Summon of this card is negated with "Horn of Heaven" or "Solemn Judgment" you do not get its effect.
• If you control your opponent’s "Witch of the Black Forest" and it is destroyed, your opponent gets the effect since it activates in his/her Graveyard.
• You can chain to the activation of "Witch of the Black Forest"’s effect.

WITCH OF THE BLACK ROSE

• “This card cannot be Special Summoned” is not treated as an effect.
• If you have no cards in your Deck when you activate the effect of “Witch of the Black Rose,” you will lose the Duel.
• If you activate the effect of “Witch of the Black Rose” while you have no cards in your hand and you draw “Infernity Archfiend,” you can activate the effect of “Infernity Archfiend.” You resolve the effect of “Witch of the Black Rose” like this: -Draw 1 card. If it is a monster, the effect is over. -If not, destroy “Witch of the Black Rose” and send the card drawn to the Graveyard. (Destroying and sending the card occur at the same time.)

WOLF IN SHEEP’S CLOTHING

• If a “Charmer” is removed from play with “Interdimensional Matter Transporter”, its effect is not re-applied when it’s back on the field.
• If “DNA Transplant” changes a monster’s Attribute so that it can be taken by a “Charmer”, and then “DNA Transplant” is destroyed so that the monster’s Attribute no longer corresponds to the effect of the “Charmer”, the controller of the “Charmer” loses control of the monster.
• If the turn player controls a “Charmer” and a monster controlled by its effect, and activates “Assault on GHQ” and targets the controlled monster, and the opponent chains an effect to destroy the “Charmer”, the controlled monster returns to the opponent’s control, but is still destroyed by the effect of “Assault on GHQ”.
