If you would take damage from a card effect, place 1 Black Feather Counter on this card instead. This card loses 700 ATK for each Black Feather Counter on it. Once per turn: You can remove all Black Feather Counters from this card, then target 1 face-up monster your opponent controls; that target loses 700 ATK for each Black Feather Counter removed, and if it does, inflict damage to your opponent equal to the ATK lost by this effect.
