Kallistor, Eternal Knight

Menace, Lifelink

Whenever Kallistor attacks, exile a creature card
from a graveyard. Create a 2/2 black Zombie Knight creature token
At the beginning of your end step, if a creature you controlled died this turn, you may return target creature card exiled with Kallistor to the battlefield under your control. It becomes a black Zombie in addition to its other types.
