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 Megatog 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 transforms a simple cat-and-oven routine into a devastating engine by turning your entire board into a synergistic feast. Encroaching Mycosynth sets the foundation by making all your nonland permanents artifacts, which instantly supercharges Ragost, Deft Gastronaut to grant every single one of them the Food subtype and a lifegain-triggered untap. With weapons ready, Weapons Manufacturing automatically churns out a Munitions token every time a nontoken artifact enters, giving you a fresh sacrificial payload whenever Cauldron Familiar drops. You can then use Megatog to clear the Familiar into the graveyard, and since the Munitions tokens count as Foods thanks to Ragost, you can feed one to bring Cauldron Familiar right back. The leaving-the-battlefield trigger from the sacrificed Munitions deals direct damage, finishing off your opponents in a flurry of recycling metal and claws.
