Cauldron Familiar

Ragost, Deft Gastronaut

Weapons Manufacturing

Krark-Clan Grunt

Mycosynth Lattice

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 ingenious loop turns a modest cat into a lethal engine by rewriting the rules of the battlefield. Mycosynth Lattice ensures every permanent in play is an artifact, which immediately supercharges Ragost, Deft Gastronaut to turn all those artifacts—including the Munitions tokens created by Weapons Manufacturing—into edible Foods. You cast Cauldron Familiar to drain your opponents while triggering Weapons Manufacturing, then feed the cat to Krark-Clan Grunt to send it to the graveyard. From there, you use the Munitions token as the Food sacrifice required by Cauldron Familiar's own ability, causing the token to leave the battlefield and trigger its 2 damage payload while the cat leaps right back onto the battlefield to do it all over again.
