Effect
If each player has an Extra Deck: Declare 1 Extra Deck monster card type (Fusion, Synchro, or Xyz); both players reveal their Extra Deck, and the player who has more cards of the declared card type gains 3000 Life Points.
Cannot be activated during the Damage Step.
Cannot be activated if there are no cards in your or your opponent's Extra Deck.
The type of monster card is declared when the card is activated.
You may declare a type even if there are no cards of that type in your Extra Deck.
Regardless of which type is declared, both players will check all cards in both Extra Decks.
Whether the number of cards of the declared type is higher or lower is determined by the number of cards found when both players check the Extra Decks during the resolution of the effect.
If the number of cards of the declared type is the same, neither player gains Life Points, and the effect finishes resolving.
