This loop harnesses the persistent board-wipe of Pyrohemia to repeatedly damage your own creatures—specifically pumping them with Sonic the Hedgehog: Haste, which turns that incoming damage into a wealth of Treasure tokens. Archelos, Lagoon Mystic plays a subtle yet critical role here: because its static ability dictates that other permanents enter untapped while it is untapped, the Treasures produced by Sonic's triggered ability hit the battlefield ready to be used immediately. You can then instantly crack those Treasures for red mana to feed Pyrohemia's activation cost, fueling a continuous cycle that generates near-infinite colored mana, artifact triggers, and damage to all players.
