Thermopod

How it works

1. Cast Cauldron Familiar by paying .
2. When Cauldron Familiar enters, it and Weapons Manufacturing trigger.
3. Resolve the Cauldron Familiar trigger, causing each opponent to lose 1 life and you to gain 1 life.
4. Resolve the Weapons Manufacturing trigger, creating a Munitions artifact token.
5. Activate Thermopod by sacrificing Cauldron Familiar.
6. Activate Cauldron Familiar by sacrificing the Munitions, as it is a Food due to Ragost.
7. The Munitions triggers, dealing 2 damage to any target.
8. Resolve the Cauldron Familiar ability, returning it from your graveyard to the battlefield.
9. Repeat from step 2.

This intricate loop transforms a humble cat into a relentless engine of destruction by turning every single permanent you own into a viable resource. Encroaching Mycosynth sets the stage by making all your nonland permanents into artifacts, which in turn are instantly drafted as Foods thanks to Ragost, Deft Gastronaut. When you cast Cauldron Familiar, its entry triggers both its own life drain and Weapons Manufacturing, which spits out a Munitions token to help fuel the loop. You then sacrifice the Cat to Thermopod for red mana, and use that mana alongside the Munitions—now masquerading as a Food via Ragost—to trigger Cauldron Familiar's recursive return from the graveyard. This dance repeats infinitely, yielding boundless sacrifice triggers, life swings, and lethal damage to sweep the table clean.
