This loop transforms Rot Hulk's graveyard-recursion entry trigger into a self-sustaining engine by leveraging the copying power of Necroduality. Whenever Rot Hulk enters the battlefield, you sacrifice it to Thermopod for red mana, allowing the original to hit the graveyard just in time for its own delayed trigger—or its token copy—to pull it right back out. Necroduality ensures that every iteration spawns a fresh token copy of Rot Hulk, which in turn triggers its ability to recur the original Rot Hulk and any other needed Zombies. With Thermopod converting each sacrificed Hulk into the red mana needed to keep the board cycling, you generate an endless cascade of enters-the-battlefield triggers, deaths, and fiery mana.
