This ingenious loop revolves around the synergy between Wingrattle Scarecrow and Stalwart Successor, where the Scarecrow's persist ability returns it to the battlefield with a -1/-1 counter, which immediately triggers the Successor to place a +1/+1 counter on it. Because these two opposing counters annihilate each other as a state-based action, the Wingrattle Scarecrow is left completely clean of counters and ready to be sacrificed all over again. By feeding this resilient loop into Thermopod, you can sacrifice the Scarecrow indefinitely to turn this perpetual motion machine into a gusher of red mana alongside infinite entry, death, and sacrifice triggers.
