Legendary Creature — Homunculus1/1
At the beginning of your upkeep, look at the top two cards of your library, then put one of them into your graveyard. Whenever a creature card is put into your graveyard from your library or hand, it perpetually gains "When this card leaves your graveyard, create a tapped 2/2 black Zombie creature token."
