Awaken the Graveborn

Descend (If you have eight or more creature cards
in your graveyard, you get the crypt's blessing for the
rest of the game.)
Exile any number of target creature cards from
your graveyard. Create an X/X black Zombie
Giant creature token, where X is the number of
cards exiled this way. If you have the crypt's
blessing, you may put any number of creature
cards exiled this way on top of your library in
any order.
