Vampire Aristocrat
The name is the whole template: this is the rules-text skeleton of the sacrifice-payoff archetype that would later get an actual mechanical keyword. Strip away the flavor and what's left is a free, repeatable sacrifice outlet stapled to a body that grows each time you feed it. That combination is the load-bearing piece. A free outlet means you can crack creatures in response to removal, denying the kill or fizzling a graveyard hatebear's window; the no-mana-cost activation is what lets it function as combo glue rather than just a beater. The +2/+2 is almost incidental: in a deck running death triggers, tokens, and recursion, the relevant text is "Sacrifice a creature," and the pump is the consolation prize you take when you have nothing better to do with the bodies. Designs in this lineage have ranged from the dirt-cheap Carrion Feeder to the engine-scale Viscera Seer, each trading body size or upside for the same core utility: a sacrifice valve that costs nothing to pull. This one sits in the middle, a 2/2 that can become a real clock if you have fuel to burn but earns its slot as the outlet, not the threat. It is one of the cleaner statements of why a sacrifice deck wants a board of expendable creatures in the first place: the outlet turns every disposable body into mana-free flexibility.
