This clever loop turns the graveyard into a devastating engine by leveraging the unique cost reduction of Norman Osborn // Green Goblin alongside its Goblin Formula ability. Because Green Goblin allows you to cast spells from your graveyard for their normal costs with a discount, Ebondeath, Dracolich can be repeatedly cast straight from the graveyard the moment any other creature dies. Sacrificing Ebondeath to Phyrexian Altar generates the mana needed to replay it, while Bridge from Below steps in to automatically supply a fresh Zombie token whenever Ebondeath hits the graveyard. Sacrificing that token back to Phyrexian Altar provides the exact trigger Ebondeath needs to return, creating a seamless, infinite loop of sacrifices and death triggers.
