Balmor, Battlemage Captain
Spellslinger payoffs usually reward you in card advantage or storm count; this one rewards you in reach. The trigger fires on every instant or sorcery you cast, not once per turn, so a chain of cheap cantrips and burn stacks +1/+0 and trample onto your whole board at once. That reframes what the deck is trying to do: instead of assembling a combo or grinding value, you are building a wide token board and then converting a single turn of spellcasting into lethal, with trample stepping past the chump blockers that normally wall a go-wide attack. The 1/3 flyer body is beside the point; it is a cheap two-mana enabler that survives most sweepers-of-convenience and evades ground defense on its own. What makes the design tick is the interplay of the two clauses. Trample is what keeps the pump from being blanked by a lone blocker, and the per-cast wording is what lets a modest spell count snowball into a swing that ends the game. Izzet has plenty of payoffs that reward casting many spells, but most of them route that reward into direct damage or draw. Directing it at the combat step instead makes this a distinct archetype anchor: an aggressive, board-centric spellslinger rather than the usual burn-or-loop engine.
