This clever loop transforms the graveyard into a recycling engine, starting when Norman Osborn // Green Goblin uses its backside's Goblin Formula ability to grant your graveyard cards mayhem for their mana costs. Because Green Goblin discounts spells cast from the graveyard by {2}, Ebondeath, Dracolich's revival cost is reduced to just its black mana pips, allowing it to easily slip back onto the battlefield whenever another creature dies. Meanwhile, Oketra's Monument generates a steady stream of Warrior tokens to fuel Phyrexian Altar, which happily turns those disposable bodies—and Ebondeath itself—into the mana needed to repeat the whole cycle infinitely.
