Cauldron Familiar + Ragost, Deft Gastronaut + Weapons Manufacturing + Ravenous Intruder + Mycosynth Lattice

Cauldron Familiar

Ragost, Deft Gastronaut

Weapons Manufacturing

Ravenous Intruder

Mycosynth Lattice

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 Ravenous Intruder 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 cunning loop turns your entire board into an engine of continuous destruction, anchored by Mycosynth Lattice making every permanent in play an artifact so that Weapons Manufacturing spits out a Munitions token whenever anything enters. Ragost, Deft Gastronaut ties the entire apparatus together by generously granting all those artifacts the Food subtype—and critically providing the untap trigger at the end step, though here we bypass waiting by directly converting those Munitions into fuel. By repeatedly sacrificing Cauldron Familiar to Ravenous Intruder, you bin the cat so it can immediately feast on a Munitions (treated as a Food thanks to Ragost) to trigger its own return, sending the Munitions away to deal 2 damage as it leaves while draining opponents and gaining you life anew.
