Night-Creed Cultist

Linger (When this creature dies, return it to the battlefield face down as a 2/2 creature. Turn it face up at any time for its mana cost.)
When Night-Creed Cultist is turned face up, manifest a card at random from your graveyard (put it onto the battlefield face down as a 2/2 creature. Turn it face up at any time for its mana cost if it's a creature card.)
Devotion beyond death.
