Target 1 Zombie monster on the field; make it either gain or lose 1000 ATK until the end of this turn. If this card is in your GY: You can shuffle 1 of your banished Zombie monsters into the Deck, and if you do, Set this card, but banish it when it leaves the field. You can only use 1 "Zombie Power Struggle" effect per turn, and only once that turn.
