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 Bartolomé del Presidio 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 relentless loop transforms a simple cat into a devastating engine of attrition, turning your entire board into a feast for the graveyard. Encroaching Mycosynth sets the stage by turning all your permanents into artifacts, which allows Ragost, Deft Gastronaut to magically imbue every single one of them with the vital Food type and ready its untapping ability. When Cauldron Familiar enters the battlefield, it drains your opponents while Weapons Manufacturing automatically crafts a Munitions token to replace it. You can then use Bartolomé del Presidio to feed the cat to the graveyard, only to immediately sacrifice the Munitions token as a Food to bring Cauldron Familiar right back—triggering the Munitions token's explosive departure and beginning the cycle anew.
