Cauldron Familiar

Ragost, Deft Gastronaut

Weapons Manufacturing

Krark-Clan Grunt

Encroaching Mycosynth

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 Krark-Clan Grunt 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 loop turns a simple cat into an infinite engine of life-draining devastation by binding every piece of your board into a cohesive whole. Encroaching Mycosynth quietly sets the stage by turning all your nonland permanents into artifacts, which in turn allows Ragost, Deft Gastronaut to blanket your entire setup with the Food type and its accompanying life-gain synergy. When Cauldron Familiar enters the battlefield, it triggers Weapons Manufacturing to spit out a Munitions token; you then sacrifice the cat to Krark-Clan Grunt, and use that very Munitions token—now acting as a Food thanks to Ragost—to fuel Cauldron Familiar's return from the graveyard. The Munitions token's departure triggers its own blast of damage, while the continuous cycle of life gain keeps Ragost constantly untapping to unleash even more punishment.
