This intricate loop transforms a humble cat into a devastating artillery piece by turning every permanent on the board into a legitimate culinary resource. Mycosynth Lattice lays the groundwork by making all permanents artifacts, which seamlessly feeds Ragost, Deft Gastronaut's static ability to give your entire board the Food type. When you cast Cauldron Familiar, its entry triggers Weapons Manufacturing to spit out a Munitions token while the cat drains life, allowing Phantom Train to sacrifice the cat to animate itself. You can then use the Munitions token as the Food required to bring Cauldron Familiar right back from the graveyard, triggering the Munitions' departure damage to a target in the process. Ragost's untap ability ensures your Gastronaut stays ready for action, ultimately fueling an unstoppable cycle of life-draining loops and infinite damage.
