Cirith Ungol Patrol

A sacrifice outlet that pays you twice. The activation converts one creature into a card and a Food token, which means every death you feed it advances two separate resource axes: raw card advantage and a stockpiled life-gain artifact you can cash in later. That doubling is what distinguishes it from the long line of aristocrat engines whose fodder-eaters draw or drain but do not manufacture a second permanent on the way. The design points squarely at graveyard-and-token decks that want to sacrifice cheaply and repeatably: the outlet costs only one mana to fire, so it scales with how much expendable material the rest of the board can generate. The Food it produces is the quiet load-bearing piece, since it turns each sacrifice into deferred life the deck can spend when the aggression runs the other direction, and it feeds any strategy that cares about artifacts hitting the battlefield or being sacrificed in turn. The 4/5 body matters less than the tap symbol: the outlet is once per turn without help, so the ability rewards untap tricks and additional sacrifice engines rather than functioning as a burst. What it offers is a slow, grinding conversion of bodies into cards and life, built for the kind of board state where creatures are cheap and the game goes long.
