Stampede Driver

Overrun on a 1/1 stick, refinanced through your hand rather than your curve. The activated ability hands your whole team +1/+1 and trample until end of turn, which reads as a modest combat trick in isolation but on a developed board becomes a finisher: trample is the operative word, converting a stalled creature count into damage that chump-blocking cannot soak. The constraints are deliberate and they shape the deck around it. Tapping to activate caps the swing at once per turn absent an outside untapper, and each use costs both two mana and a card from hand, so the engine spends your grip in exchange for reach. That is the central tension of the design: a 1/1 that demands a wide board, open mana, and a card to feed it. It rewards the deck that has already done its developmental work and punishes the one holding it in topdeck mode. The Spellshaper template (sorcery-style effects bolted onto cheap bodies, financed by discard rather than a slot on the curve) was an early-era answer to how an aggressive deck could carry a recurring threat-and-payoff in the same one-drop. Deployed early, it costs almost nothing to hold back; deployed as a closer, it asks you to spend a card on the exact turn a creature count converts to lethal, which is precisely the turn a go-wide deck is happy to be spending cards.
