Hammerhead, Maggia Boss

A sacrifice sink with no mana cost and no cap, priced only by the resource tax of whatever it eats: this is the pure aristocrats payoff, a body that wants fodder generators upstream and rewards the same board-draining loops that death triggers already feed on. The activation is broad enough to swallow creatures and artifacts alike, which folds Treasure and token engines into the fuel supply, and each meal converts into a counter that stays put rather than a pump that fades at end of turn. That durability is the whole distinction: growth compounds across the game instead of resetting, so the ceiling is bounded by how much you can spend feeding it rather than by any built-in rate. The trade the design makes is stark. The counters stick, but everything eaten is gone, and the 2/1 starts fragile enough that a single removal spell erases the invested value before the counters can turn a corner. An empty board leaves it inert; it is a payoff, not an engine, waiting on the sacrifice machinery built around it. Once that machinery exists, though, it scales faster than most repeatable pump effects for a simple reason: the growth is durable and the fuel is renewable, so every turn you can rebuild fodder is another turn the attacker gets larger and the invested value gets harder to unwind.
