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 Yahenni 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 engine transforms your graveyard and battlefield into an inescapable loop of life-draining carnage, all built around a clever type-shifting foundation. Biotransference ensures your creatures are also artifacts, allowing Weapons Manufacturing to flood the board with Munitions tokens every time Cauldron Familiar enters the battlefield. Meanwhile, Ragost, Deft Gastronaut turns all of those artifacts into Foods, which gives Cauldron Familiar the exact fuel it needs to constantly recur itself from the graveyard. Finally, Yahenni, Undying Partisan acts as the initial sacrifice outlet to kickstart the cycle, letting you infinitely trigger the death and damage effects of your looping pieces until the table falls.
