Cauldron Familiar + Ragost, Deft Gastronaut + Weapons Manufacturing + Krark-Clan Ironworks + Biotransference

Cauldron Familiar

Ragost, Deft Gastronaut

Weapons Manufacturing

Krark-Clan Ironworks

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 Krark-Clan Ironworks 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 the humble **Cauldron Familiar** into a terrifying multi-engine threat by fundamentally rewriting the rules of your battlefield with **Biotransference**, which makes your creatures artifact spells and artifacts everywhere, and **Ragost, Deft Gastronaut**, which turns all your artifacts into Foods. When you cast your Familiar, Biotransference ensures it triggers **Weapons Manufacturing** to spit out a Munitions token, while Ragost transforms that very token into a valid Food sacrifice for the cat's graveyard ability. You then feed the cat to **Krark-Clan Ironworks** for colorless mana to recast it, while the Munitions token leaves the battlefield to hurl 2 damage at any target. Ragost even untaps itself at the end step thanks to the lifegain from the cat's entrance, letting you easily close out a game in Commander, Legacy, Oathbreaker, or Vintage through an endless cascade of life loss, damage, and artifact sacrifices.
