With numerous Fusion strategies available in Edison Format, it is important to fully understand this game mechanic. For example, "Versago the Destroyer's" unclassified effect (that cannot be negated) applies while in the hand, Graveyard, and on the field allowing it to be substituted for 1  specifically listed Fusion Material Monster when performing a Fusion Summon. However, this effect does not apply in the Deck / while it is removed from play, nor will it apply if the Summoning method is not specifically a Fusion Summon. The "Hex-Sealed Fusions'" Ignition Effects tribute themselves and the correct Fusion Material to Special Summon Fusion Monsters of their respective Attributes (this is not a Fusion Summon). But there is more to Fusion Monsters, their Conditions especially!

A number of 'flip flop' monsters have been printed over the years with a range of Trigger Effects which activate upon Flip Summon. Such 'flip flop' monsters have the ability to Set themselves face-down so that their one manual position change can be used to Flip Summon them. However, given everyone's familiarity with "Book of Moon's" ability to 'reset' many 'once per turn' effects, a question often arises: "Since it flipped face-down, can it use it's effect again?"

The gamestate remembers that these 'once per turn' effects were used to Set the monster before its Flip Summon this turn [REF1, REF2, REF3, REF4, REF5].

The Format Rules page has been updated to include rulings for "Trap Monsters". These rulings will be especially useful if you're considering innovating a Deck around "Uria, Lord of Searing Flame" (have you read our last blog post about Special Summons that DO/DO NOT use the chain? Uria makes an appearance)! Trap Monsters that can't be destroyed by battle? "Heavy Storm" resulting in a mere 1-for-1 exchange? Check it out the rules pertaining to "Imperial Custom" in the Individual Rulings & Errata page and let us know if we missed anything!

The 6 Trap Monsters available for play in Edison Format are (from left to right):
- Cyber Shadow Guardna
- Embodiment of Apophis
- Machine King - 3000 B.C.
- Metal Reflect Slime
- Stronghold the Moving Fortress
- Zoma the Spirit

Unsure what your opponent means by "it doesn't activate, it misses the timing"? Confused why your opponent is saying "during damage calculation" before activating Kalut? Unsure why Catastor doesn't destroy face-down monsters but a FLIP monster's effect still activates after being shuffled back into the Deck by Ehren? We've been hard at work compiling a thorough "Rulings & Erratas" page complete with the most updated card texts that were available at the time of SJC - Edison 2010. Find hidden tech to up your game and innovate new strategies!
