This loop transforms Ebondeath, Dracolich into an endlessly recurring sacrifice engine by leveraging the passive cost-reduction of Doc Aurlock, Grizzled Genius. Since Ebondeath can be cast directly from your graveyard whenever another creature dies—a condition easily met by sacrificing it—you only need to cover its casting cost, which Doc Aurlock happily reduces down to a mere two black mana. Phyrexian Altar turns Ebondeath into your first piece of mana, while Pitiless Plunderer steps in to provide the second mana source through the Treasure token it creates upon every death. Together, these pieces generate an infinite stream of sacrifices, enters-the-battlefield triggers, and storm count without ever running dry.
