Cauldron Familiar + Ragost, Deft Gastronaut + Weapons Manufacturing + Atog + Encroaching Mycosynth

Cauldron Familiar

Ragost, Deft Gastronaut

Weapons Manufacturing

Atog

Encroaching Mycosynth

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 Atog 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 is a masterclass in turning everyday permanents into a lethal feedback engine, anchored entirely by Encroaching Mycosynth ensuring that everything you own—including Cauldron Familiar and Atog—treats itself as an artifact. Ragost, Deft Gastronaut then steps in to grant all those newly minted artifacts the crucial Food type, transforming Weapons Manufacturing into a factory that churns out Munitions whenever a nontoken artifact enters. You feed that Cauldron Familiar to Atog, then sacrifice the Munitions-as-Food to bring the Familiar right back from the graveyard, triggering a recursive cascade of life loss, damage, and artifact triggers that quickly buries the table.
