Devilswood Graveyard

When a player successfully casts a World Enchantment, sacrifice all other World Enchantments.
Creatures of the creature type Zombie, Demon, Vampire and Horror get Deathtouch. Whenever a nontoken creature dies, that creatures controller creates a tapped 2/2 black Zombie creature token.
At the beginning of your upkeep pay {b}{b} or sacrifice Devilswood Graveyard.
