This loop hinges on a clever interaction between Solemnity and Chronozoa, completely bypassing the creature's vanishing drawback by preventing time counters from ever being placed upon it. Because Solemnity ensures that Chronozoa and its future copies enter the battlefield completely barren of time counters, the moment you sacrifice a copy to Thermopod, its death trigger immediately sees zero counters and spits out two brand-new token copies. Those tokens also enter with no counters thanks to Solemnity, allowing you to feed them back into Thermopod's sacrifice ability to endlessly generate red mana and an infinite army of creatures.
