Kalitas, Traitor of Ghet

Lifelink
If a nontoken creature an opponent controls would die, instead exile that card and create a
2/2 black Zombie creature token.
{2}{b}, Sacrifice another Vampire or Zombie: Put two +1/+1 counters on Kalitas, Traitor of Ghet.
A dagger has only a single point, but a traitor cuts from everyhwere.
