Mask of Darkness

At the beginning of your upkeep, sacrifice Mask of Darkness unless you sacrifice another creature.

Whenever a creature you control dies, create a 2/2 black Zombie creature token with deathtouch.

Whenever a creature is equipped, it gets +X/+X for each creature in all graveyards and is now "Majora, the Dark Deity," and is a Demon God in addition to its other type.
