mtg transform cards in MTG: Rules, History, and Best This limited Rules Text: Transform, Subtype: Werewolf,
Description
You will need at least one other Zombie in play to be able to cast Gravecrawler from the graveyard, but once you get going, you can keep sacrificing your spare Zombie token to keep looping death triggers for whatever outlet you need
