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 Extruder 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 simple cat into a relentless engine of destruction by turning your entire board into a buffet. Thanks to Encroaching Mycosynth, every permanent you control becomes an artifact, which in turn causes Ragost, Deft Gastronaut to treat them all as Foods while providing the activation cost needed to weaponize them. When you cast Cauldron Familiar, Weapons Manufacturing steps in to spin off a Munitions token upon entry, fueling Extruder with fodder to feed the cat back into the graveyard. The cat's own entry drains your opponents and gains you life, which conveniently satisfies Ragost's end step condition while also letting you sacrifice the Munitions token as a Food to bring the Familiar right back to the battlefield.
