Resolve the Weapons Manufacturing trigger, creating a Munitions artifact token.
Activate Woe Strider by sacrificing Cauldron Familiar.
Activate Cauldron Familiar by sacrificing the Munitions, as it is a Food due to Ragost.

This intricate alchemy hinges on turning your entire battlefield into a sweet treat factory, fueled by Mycosynth Lattice making every permanent an artifact. With Ragost, Deft Gastronaut casting its culinary influence, those newly minted artifacts—including the Munitions tokens spawned by Weapons Manufacturing—are successfully recognized as Foods. This allows you to effortlessly loop Cauldron Familiar by sacrificing the Munitions to pay its revival cost, while Woe Strider stands ready to sacrifice the cat right back into the graveyard. As the loop spins, the leaving-the-battlefield trigger from the sacrificed Munitions deals explosive damage to any target, draining the opposition while Ragost handily untaps itself each end step thanks to the steady stream of lifegain.
