When Cauldron Familiar enters, it, Grinding Station and Weapons Manufacturing trigger.
Resolve the Grinding 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.
When the Munitions token enters, Grinding Station triggers, untapping Grinding Station.
Activate Grinding 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 clever loop turns Biotransference and Ragost, Deft Gastronaut into the ultimate kitchen suite, ensuring that your creatures—and every artifact they spawn—are treated as Food. As Cauldron Familiar repeatedly hops into and out of the graveyard, it triggers Weapons Manufacturing to spit out Munitions tokens, which simultaneously satisfy the Food cost for the cat's return and deal burning damage when sacrificed. Meanwhile, Grinding Station stands ready to constantly untap itself from these endless artifact entries, fueling an entire storm of triggers that will mill your opponents out and incinerate their life totals in one fell swoop.
