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 Shilgengar 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 intricate engine turns your entire battlefield into a perpetual-motion machine by leveraging Encroaching Mycosynth to make all your nonland permanents into artifacts, which Ragost, Deft Gastronaut then transforms into Foods. With Ragost granting those artifacts the ability to be sacrificed as Foods, you can feed the Munitions token created by Weapons Manufacturing to resurrect Cauldron Familiar from your graveyard. Each time the Familiar enters, it triggers Ragost's lifegain condition to keep it untapping, while Shilgengar, Sire of Famine lurks nearby as an alternative sacrifice outlet to churn out Blood tokens when needed.
