Cartel Aristocrat

The protection clause is the engine here, not the body. A 2/2 with a free sacrifice outlet is unremarkable until you notice what protection actually does: protection from a color means this creature cannot be blocked by, targeted by, dealt damage by, or enchanted and equipped by sources of that color, so each creature you feed it buys a way to sidestep a removal spell or push damage through a blocker. The fodder is the cost and the answer is the upside, which turns dying creatures into evasion and resilience on demand. That dual identity (free sacrifice outlet plus on-demand color protection) is what makes it a natural anchor for sacrifice-based shells, where creatures dying is the point rather than the price. The protection choice resets each activation, so against a removal spell on the stack you can respond by naming its color and watching it lose its only legal target. The constraint that pays for that flexibility is the word "another": the sacrifice can never hit itself, so it always needs a board to draw from, and it cannot fizzle an exile effect by eating its own body. What it lacks in raw pressure it returns in survivability, a repeatable outlet that asks for fodder and pays back in dodges. It is glue for a sacrifice deck rather than a card that closes a game on its own.
