This looping engine turns a humble skeleton into a relentless sacrifice machine by harnessing a brilliant web of triggers and mana generation. Reassembling Skeleton provides the recurring body, which you feed to Umbral Collar Zealot to filter your draws with surveil while triggering the rest of the board. Every time a creature hits the graveyard, Pitiless Plunderer refunds your investment by spitting out a Treasure token to help pay for the skeleton's return, while Bridge from Below steps in to populate your side with fresh Zombie tokens to keep the sacrificial fires burning.
