This clever loop relies on Dino DNA to bypass Su-Chi's usual status as a one-shot resource, continuously resurrecting it as a monstrous 6/6 Dinosaur copy. Once you pay the initial activation cost, Krark-Clan Ironworks steps in to devour the Su-Chi token for mana, instantly triggering the creature's death ability to yield a net positive mana return. Because the mana generated by the sacrifice and the resulting death trigger exceeds the cost to forge a new token through Dino DNA, you can cycle this sequence endlessly to generate infinite death triggers, sacrifice triggers, and creature entries.
