Slaughter-Priest of Mogis

A sacrifice-payoff whose two lines feed each other, and the loop is the whole design. The first ability is a passive kicker: every permanent you sacrifice, from any source, pumps this Minotaur for the turn, so it wants to sit on the battlefield while an aristocrats engine chews through fodder around it. The second ability lets it do that sacrificing itself, eating your own creatures and enchantments for first strike, which in turn triggers the first ability and stacks another +2/+0. That reflexive relationship is what separates it from most payoffs its size: rather than draining the opponent or refilling your hand, it converts each sacrifice into raw combat pressure with no ceiling within a turn, and the activated line both keeps the pump ticking and gives the swollen body first strike so it wins the exchange against a blocker instead of trading. The role it describes is specific: not the sacrifice outlet at the center of the deck, but the thing that grows every time one fires and can, at a two-mana tax, act as a backup outlet that also profits from the trade. Both halves reward a board you are actively dismantling, which is exactly the deck it was built for: one that treats its own permanents as ammunition and wants a red-black finisher pointed at the opponent's face.
