When Cauldron Familiar enters, it and Weapons Manufacturing trigger.
Resolve the Cauldron Familiar trigger, causing each opponent to lose 1 life and you to gain 1 life.
Resolve the Weapons Manufacturing trigger, creating a Munitions artifact token.
Activate Goblin Bombardment by sacrificing Cauldron Familiar.
Activate Cauldron Familiar by sacrificing the Munitions, as it is a Food due to Ragost.
The Munitions triggers, dealing 2 damage to any target.
Resolve the Cauldron Familiar ability, returning it from your graveyard to the battlefield.
Repeat from step 2.
This loop turns a simple cat-and-oven dynamic into a devastating engine by weaving together artifact synergies and continuous sacrifice outlets. Mycosynth Lattice lays the foundational groundwork by making every permanent an artifact, ensuring that Weapons Manufacturing triggers every time a creature enters and manufactures a Munitions token. Meanwhile, Ragost, Deft Gastronaut transforms all those artifacts into literal Foods, allowing Cauldron Familiar to bypass its usual dietary restrictions and leap right back out of the graveyard by sacrificing the newly minted Munitions. Finally, Goblin Bombardment provides the sacrificial push to send the Familiar back to the graveyard in the first place, while the Munitions dying trigger packs an explosive punch to seal the deal.
