Cauldron Familiar

Ragost, Deft Gastronaut

Weapons Manufacturing

Encroaching Mycosynth

Carrion Feeder

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 Carrion Feeder 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 your entire board into a relentless engine of destruction, anchored by Encroaching Mycosynth ensuring that every single nonland permanent you control is an artifact. Because Ragost, Deft Gastronaut is on the field, those artifacts—including the Munitions tokens generated by Weapons Manufacturing every time a nontoken artifact enters—are also treated as Foods, providing the exact sacrifice fodder Cauldron Familiar needs to crawl back from the graveyard. As the Familiar loops between the battlefield and the graveyard, Carrion Feeder acts as the initial executioner while its death and sacrifice triggers repeatedly fuel your engine, with Ragost converting your artifact sacrifices into direct damage and untapping itself via your constant lifegain.
