When Cauldron Familiar enters, it, Blasting Station and Weapons Manufacturing trigger.
Resolve the Blasting Station trigger, untapping it.
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 Blasting Station by tapping it and 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 intricate loop transforms a simple cat into a devastating artillery engine, fueled entirely by turning every permanent on the board into a snack. Mycosynth Lattice lays the groundwork by making everything an artifact, which lets Ragost, Deft Gastronaut grant every single one of them the Food subtype and a built-in sacrifice ability. Whenever Cauldron Familiar enters the battlefield, Weapons Manufacturing generates a Munitions token whose departure deals fiery damage, while Blasting Station resets itself to endlessly fling your creatures. By looping the Familiar's resurrection using the Munitions-turned-Food, you trigger a continuous storm of sacrifice, damage, and lifegain that leaves your opponents buried in debris.
