Scrapyard Steelbreaker

The reward attached to an artifact-sacrifice engine, packaged in a body that can end games by itself. The 3/4 frame matters here: it survives most early combat and blocks upward, so the pilot is never forced to pump defensively. The activated ability turns the graveyard-feeding half of an aristocrats build into a clock, converting each spent artifact into a +2/+1 swing and repeatable pressure. Because the boost fades at end of turn and costs one mana per activation, the card scales with how much fodder the board can spare rather than promising an unbounded finish: a hand with three Treasures or expendable Clues becomes a lethal push, an empty board makes it a plain beater. That is the balancing act, the payoff is real but strictly rationed by resources you have to build toward. It belongs to the strain of red artifact aggressors that ask a deck to treat its artifacts as ammunition rather than permanents, a design red keeps returning to whenever it wants a sacrifice theme to close a game rather than merely grind one out. The Human Warrior line and artifact-creature status also let it double as fuel for other sacrifice payoffs, so a single copy can be both the engine's finisher and its final input.
