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 Phyrexian Altar 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 turns a humble cat into a devastating engine of attrition by blurring the lines between creatures and artifacts. Thanks to Biotransference, Cauldron Familiar is treated as an artifact card everywhere, meaning its entrance triggers Weapons Manufacturing to produce a Munitions token and satisfies Ragost, Deft Gastronaut's end-step untap condition if needed. Ragost's static ability is the linchpin that redefines every artifact you control—including the Munitions tokens—as a Food, allowing you to feed them directly into Cauldron Familiar's recursion ability from the graveyard. Finally, Phyrexian Altar lets you sacrifice the cat for mana while it bounces back and forth, fueling a relentless cycle of damage, lifegain, and carnage.
