Cauldron Familiar + Ragost, Deft Gastronaut + Weapons Manufacturing + Viscera Seer + Biotransference

Cauldron Familiar

Ragost, Deft Gastronaut

Weapons Manufacturing

Viscera Seer

Biotransference

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 Viscera Seer 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-and-oven dynamic into a sweeping execution, made possible because Biotransference turns Cauldron Familiar into an artifact creature that triggers Weapons Manufacturing whenever it enters the battlefield. Weapons Manufacturing hands you a Munitions token upon arrival, which Ragost, Deft Gastronaut conveniently reclassifies as a Food alongside all your other artifacts. You can then sacrifice Cauldron Familiar to Viscera Seer for a peek at your library, and immediately feed that newly minted Munitions to the cat's own recursion ability. Each cycle drains life, flings damage from the departing Munitions token, and repeats indefinitely to close out the game.
