Krark-Clan Ironworks converts Myr Retriever and Junk Diver into sacrifice fodder, and their death triggers return each other to hand while Scrap Trawler recurs Sol Ring as the mana bridge each cycle. The loop is colorless, meaning it slots into any artifact-heavy commander — Kozilek, the Great Distortion, Karn, Silver Golem, or Breya, Etherium Shaper — without a single color pip on the critical pieces. Every pass through the loop generates net colorless mana and fires infinite ETB, LTB, sacrifice, and death triggers.

Cheaper, tighter, alternate lines

The loop survives losing Junk Diver if a second artifact with a death-trigger recursion effect replaces it — Scrap Trawler itself carries enough redundancy that most KCI lists run Workshop Assistant as a fifth piece alongside the core four. Walking Ballista is the cleanest kill once mana goes infinite; Disciple of the Vault converts the infinite death triggers into a win without needing the mana sink at all.
