White Glove Gourmand

A body that arrives already having done half the work: three Humans for one card, and every one of them is fuel. The Gourmand is itself a Human Noble, the two tokens it leaves behind are Human Soldiers, and each is a candidate to satisfy the end-step condition. The design is a tidy closed loop. The Soldiers are not just early bodies; they are sacrifice fodder that arms the trigger, and a Food token feeds back into whatever life-total or artifact-count subsystem the deck is built on. Read the end step carefully, though: it checks whether another Human died under your control that turn, so the Gourmand can never eat itself for value, and it wants a sacrifice outlet in play to convert those tokens on your own schedule rather than waiting on combat to trade them. That "another" wording is the governor on the engine: each Food demands a Human's death first, and once the Soldiers are spent you need a steady supply to keep the kitchen open. It draws on two black-white staples at once, the token-generating aristocrats shell and the Food subtheme, and its output scales directly with how many other Humans and sacrifice effects surround it. Alone, it is a 2/2 that leaves two 1/1s behind and stops there. Surrounded by things built to die on purpose, it becomes a per-turn Food factory that shows up with its own starting inventory.
