Grave Evacuation

At the beginning of your end step you may exile a creature card from your graveyard with a corpse counter, if you do create a tapped 2/2 black Zombie creature token for each card you own in exile with a corpse counter. {3}{B}: Put a creature you own in exile with a corpse counter onto the battlefield. Activate only as a sorcery. {flavor}The lords of Grixis rarely recruit without a preceding slaughter.
