This intricate necromantic engine relies on Planar Gate to discount creature spells while Pitiless Plunderer converts your casualties into the mana needed to keep the cycle moving. You begin by casting Ebondeath, Dracolich directly from your graveyard, which triggers Geralf, the Fleshwright to generate a 2/2 Zombie Rogue token and feed both creatures growing +1/+1 counters. From there, Umbral Collar Zealot sacrifices both Ebondeath and the token to fuel the loop, instantly triggering Pitiless Plunderer to refund your mana via Treasure tokens. Because Ebondeath can continually recur from the graveyard whenever another creature dies, you can repeat this sacrifice-and-cast cycle indefinitely for boundless triggers and counters.
