Individual Card Rulings [I-K]

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.

ICARUS ATTACK
Tribute 1 Winged Beast-Type monster. Destroy 2 cards on the field.

• Tributing a (face-up / face-down) Winged-Beast is a cost.
• This card targets two cards. "Icarus Attack" CANNOT target itself.
• If one target leaves the field, the other target is still destroyed when this effect resolves.

ICE QUEEN

• “This card cannot be Special Summoned from the Graveyard” is not an effect.
• This effect targets 1 Spell Card in your Graveyard.If you have 3 or more Spellcaster-Type monsters in your Graveyard, including “Ice Queen” after it is sent to the Graveyard, you can activate the effect.
• If “Ice Queen” is equipped to “Relinquished” while face-up and is destroyed and sent to the Graveyard, you can activate the effect.

IDO THE SUPREME MAGICAL FORCE

• The effect of “Ido the Supreme Magical Force” that Summons it in the Standby Phase, and its effect that destroys all other monsters, happen simultaneously. Therefore, you can activate “Torrential Tribute” or “Bottomless Trap Hole” when it Summons itself, as you have not missed the timing.
• If your next turn’s Standby Phase is skipped, you cannot Special Summon “Ido the Supreme Magical Force” with its effect during the following Standby Phase. The opportunity has been missed.
• If “Ido the Supreme Magical Force” is not in the Graveyard during the next Standby Phase (if it has been removed from play, for example), it is not Special Summoned, and you do not destroy any monsters with its effect.

Il Blud
(U) This card is treated as a Normal Monster while face-up on the field or in the Graveyard. (C) While this card is face-up on the field, you can Normal Summon it to have it be treated as an Effect Monster with this effect:
● (1) Once per turn, you can Special Summon 1 Zombie-Type monster from your hand or from either player's Graveyard. (2) When this card is removed from the field, destroy all Zombie-Type monsters Special Summoned by this effect.

• The (U) unclassified effect does not apply while "Il Blud" is in the Deck. It cannot be negated.
• The (C) Condition cannot be negated.
  • The additional Normal Summon does not start a chain. "Torrential Tribute" can also activate.
• The (1) Ignition Effect can Special Summon from the hand or either Graveyard.
  • This effect continuously targets the Special Summoned monster(s) on the field.
  • This effect does not target a monster in the Graveyard. It is not negated by "Necrovalley".
  • While "Zombie World" is active, you can Special Summon non-Zombie-Type monsters.
  • If you activate the effect of "Il Blud" and an effect is chained that turns it face-down, the effect still resolves and you can Special Summon a monster.
  • If a card is chained to this effect and destroys “Il Blud”, the effect to Special Summon is still resolved. The Special Summoned monster will not be destroyed by “Il Blud’s” effect.
  • If there is no monster in either Graveyard or in your hand that can be Special Summoned by this effect when it resolves, your opponent can look at your hand to verify.
• The (2) Continuous Effect does not start a chain.
  • If "Il Blud" leaves the field while resolving a Chain, destroy all Zombie-Type monsters it Special Summoned before resolving the next effect in the chain.
  • If "Il Blud" leaves the field while its effect is negated by "Skill Drain", etc., monsters Special Summoned by its effect will not be destroyed.

IMPERIAL CUSTOM
(1) Face-up Continuous Trap Cards cannot be destroyed, except "Imperial Custom". You can only control 1 "Imperial Custom".

• The (1) Continuous-like Effect does not activate.
• This effect only protects Continuous Traps from destruction.
  • Continuous Traps which destroy themselves (ex: "Call of the Haunted") are not destroyed.
  • Continuous Traps still destroy themselves if maintenance costs are not paid (ex: "Mirror Wall").
  • Trap Monsters (ex: "Zoma the Spirit") can't be destroyed by battle or card effect.
  • If "Heavy Storm" would destroy face-up Continous Trap Cards, "Imperial Custom" is destroyed but all other face-up Continuous Trap Cards (including your opponent's) remain.
• Continuous Trap Cards can still:
  • be flipped face-down (a Trap Monster targeted by "Book of Moon").
  • be returned to the Deck (by "Raiza the Storm Monarch").
  • be returned to the hand (by "Giant Trunade").
  • be removed from play (by "Caius the Shadow Monarch").
  • have their effects negated (by "Jinzo").
  • have their activation (playing face-up) negated (by "Dark Bribe"). If the activation of a Continuous Trap Card is negated, it is sent to the Graveyard. It was never face-up on the field.

IMPERIAL IRON WALL
(1) Cards cannot be removed from play.

• The (1) Continuous-like Effect does not activate.
• Cards CANNOT activate if their cost / effect would remove a card(s) from play
  • Examples: "Allure of Darkness", "Nobleman of Crossout", "Book of Life", "Bottomless Trap Hole").
• If "Imperial Iron Wall" is chained, effects earlier in the Chain resolve as much as possible.
  • Example: Player A activated "Allure of Darkness" and "Imperial Iron Wall" was chained. Player A only needs to reveal a DARK monster in hand. If they cannot, they discard their entire hand.
  • Example: "Imperial Iron Wall" was chained to "Nobleman of Crossout", the targeted monster is destroyed but it is not removed from play. No cards in the Deck are removed from play.

• If you control "Red-Eyes B. Dragon" and activate "Inferno Fire Blast" to inflict damage, and then after that resolves you activate "Non-Spellcasting Area", "Red-Eyes B. Dragon" still cannot attack because "Non-Spellcasting Area" will not negate the condition.
• If "Imperial Order" is chained to "Inferno Fire Blast", the effect of "Inferno Fire Blast" is negated but "Red-Eyes B. Dragon" cannot attack. However, if "Magic Jammer" negates the activation of "Inferno Fire Blast", your "Red-Eyes B. Dragon" can attack.
• If you activate "Inferno Fire Blast" while "Non-Spellcasting Area" is active, the effect of "Inferno Fire Blast" disappears.

• If “Koa’ki Meiru Powerhand” is destroyed by battle, its effect stops working from that point.
  • Example: if “Koa’ki Meiru Powerhand” battles “Divine Knight Ishzark,” the effect of “Koa’ki Meiru Powerhand” stops as soon as it is destroyed, and it will be removed from play by the effect of “Divine Knight Ishzark.”
• The effect negation ability of “Koa’ki Meiru Powerhand” begins when an attack target is declared. If “Koa’ki Meiru Powerhand” declares an attack on “Cyber Valley,” and the controller of “Cyber Valley” removes it from play, “Cyber Valley” will be removed from play but the controller will not draw a card, and the Battle Phase will not end, because the effect was activated on the field and is negated by “Koa’ki Meiru Powerhand.” (Also, since the number of potential attack targets has changed in this case, a replay will occur.)

KOA’KI MEIRU ROOKLORD

• Revealing “Iron Core of Koa’ki Meiru” is a cost to activate this effect.

• If you control multiple copies of “Koa’ki Meiru Speeder” and you draw “Iron Core of Koa’ki Meiru” during your Draw Phase, you can activate the effect of both monsters in a Chain.

KOA’KI MEIRU TORNADO

• Returning 1 “Iron Core of Koka’ki Meiru” from your hand to the top of the Deck is a cost. If your opponent Chains “Book of Moon” to this effect to turn a Special Summoned monster face-down, it will still be destroyed. This effect will destroy monsters that have been Special Summoned in face-down Defense Position by effects like “Morphing Jar #2.”

KOITSU
(1) Once per turn, during your Main Phase, if you control this card on the field, you can equip it to your "Aitsu" as an Equip Card, OR unequip the Union equipment and Special Summon this card in face-up Attack Position. (2) While equipped to a monster by this card's effect, increase the ATK of the equipped monster by 3000 points. (3) When it attacks with an ATK that is higher than the DEF of a Defense Position monster, inflict the difference as Battle Damage to your opponent's Life Points. (C) (1 monster can only be equipped with 1 Union Monster at a time. If the equipped monster is destroyed as a result of battle, destroy this card instead.)

• "Koitsu"'s effect that inflicts damage is only applied to a monster that is equipped with "Koitsu" by "Koitsu"'s effect; "Koitsu" itself, while a monster, does not receive this effect.

KOTODAMA

• Sheep Tokens will be destroyed by the effect of "Kotodama" since Monster Tokens are considered cards.
• If two Flip Effect monsters are flipped face-up at the same time while "Kotodama" is on the field, their effects are negated and they are destroyed.
• If 2 or more monsters with identical names are on the field when "Kotodama" is Summoned, they are all destroyed.

KOZAKY'S SELF-DESTRUCT BUTTON

• You cannot activate “Kozaky’s Self-Destruct Button” because it has no activation effect.
• If “Bait Doll” targets “Kozaky’s Self-Destruct Button”, nothing happens because the timing is inappropriate. However, “Kozaky’s Self-Destruct Button” is then destroyed by “Bait Doll”.
• “Kozaky’s Self-Destruct Button” starts a chain at the time that it is sent to the Graveyard. If “Banisher of the Light” is on the field and “Kozaky’s Self-Destruct Button” is removed from play, its effect still activates because it only has to be destroyed.

KUNOICHI

• If an effect is chained that removes "Kunoichi" from the field, its new controller still discards 1 card.
• If you give control of your face-up "Kunoichi" to your opponent while "Remove Brainwashing" is active, it is immediately returned to your control and when its effect resolves you will discard 1 card.

KURAZ THE LIGHT MONARCH
(1) When this card is Normal or Special Summoned, you can destroy up to 2 cards on the field. For each card destroyed, that card's controller draws 1 card. (2) This card cannot attack during the turn it is Normal or Special Summoned.

• This (1) optional "When... you can..." Trigger Effect can miss the timing.
  • This effect targets 1 or 2 cards on the field.
  • The "destroy" and "draw" parts are considered to resolve simultaneously.
  • If a target cannot be destroyed, the other is still destroyed.
  • If a target(s) cannot be destroyed, no card is drawn for it.

• You can activate this effect even if “Bad Reaction to Simochi” is face-up on the field.
• You can activate this effect even if “Kuribon” was attacked while face-down.
• When you use this effect, damage calculation is still conducted and “Kuribon” is considered to be destroyed by battle, so you can activate cards like “Byroad Sacrifice.”

• You can activate this effect when “Kuribon” is attacked by “Dark Ruler Ha Des.” “Dark Ruler Ha Des” will not negate the effect because it is activated before “Kuribon” would be destroyed.
• If you cannot take Battle Damage because of the effect of “Waboku” or “Tornado Wall” you cannot activate the effect of “Kuribon.”
