At the beginning of the end step, sacrifice Sutured Horror.
At the beginning of your upkeep, if Sutured Horror is in your graveyard, you may exile a black creature card other than Sutured Horror from your graveyard. If you do, return Sutured Horror to the battlefield.
As Sutured Horror enters the battlefield, exile any number of creature cards from your graveyard.
Sutured Horror’s power is equal to the total power of the exiled cards and its toughness is equal to their total toughness.
