Text (SA+errata): 6/6, Flying, Trample. ; At the beginning of your upkeep, sacrifice a non-Zombie creature, then put a 2/2 black Zombie creature token onto the battlefield. [Oracle 2009/07/08]
If you have no other non-zombies when the ability resolves, you must sacrifice this creature to itself. You may sacrifice it to itself even if you have other non-zombies. You still get a Zombie token when you sacrifice this card to itself. [Shards of Alara FAQ 2008/09/23]
If you somehow have no non-zombies when the ability resolves, then you sacrifice nothing but still get the Zombie token. [Shards of Alara FAQ 2008/09/23]
