Undead Shamblers

Delve (Each card you exile from your graveyard while casting this spell pays for {1}.)
For each creature card you exile from your graveyard to help pay Undead Shamblers casting cost, put a 2/2 black Zombie creature token onto the battlefield. If an opponent has more life than you, gain 1 life for each card exiled this turn.

Death is not always the end my friend.
