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 Lithatog 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 lethal loop turns your entire board into an infinite engine for drain, damage, and artifact synergy. Encroaching Mycosynth quietly lays the foundation by transforming all your nonland permanents into artifacts, meaning Ragost, Deft Gastronaut immediately reclassifies every single one of them—including tokens and creatures—into Foods with built-in life-gaining activations. When you cast Cauldron Familiar, its entry triggers along with Weapons Manufacturing, which pumps out a Munitions token every time a nontoken artifact enters; that Munitions is simultaneously a Food thanks to Ragost, letting you sacrifice it directly to bring the Familiar right back from the graveyard. Lithatog acts as the sacrifice outlet to send the Familiar back to the yard while growing huge, while Ragost's passive untapping condition feeds effortlessly off the endless life you are gaining to keep the engine running through every end step.
