Haunted Zombies

Banish 1 Zombie monster that has a Level from either GY, and if you do, Special Summon 2 "Haunted Tokens" (Zombie/DARK/ATK 0/DEF 0) with the same Level as that monster. 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 to your field, but banish it when it leaves the field. You can only use 1 "Haunted Zombies" effect per turn, and only once that turn.
