Archdemon of Unx
Creature — Demon
Flying, trample
At the beginning of your upkeep, sacrifice a non-Zombie creature, then create a 2/2 black Zombie creature token.
The necropolis at Unx was once a living city, its streets untrodden by death.

If you somehow control no non-Zombie creatures when the triggered ability resolves, you won’t have to sacrifice anything. You’ll still get a Zombie token.
