This elegant engine turns a simple cat-and-oven loop into a lethal artillery strike by fundamentally altering the nature of your entire board. With Encroaching Mycosynth turning every nonland permanent you control into an artifact, Ragost, Deft Gastronaut steps in to give all those artifacts the crucial subtype of Food—meaning every single thing you own can now be cracked for life or used to feed the recurring nightmare. You cast Cauldron Familiar to trigger its life-drain and prompt Weapons Manufacturing to churn out a Munitions token, which conveniently doubles as both a lethal damage source when it leaves and the Food required to pull the Familiar right back out of the graveyard. Viscera Seer lets you sacrifice the Familiar cleanly to start the cycle, while Ragost's untap ability ensures your Gastronaut is ready for any other tricks once you've gained your life.
