Elsha, Threefold Master
Two prowess payoffs stacked on the same 1/1 body, and the second one turns the first into a runaway feedback loop. Prowess makes each noncreature spell a temporary pump; the combat-damage trigger converts whatever that pump adds up to into a permanent army of tokens, each of which carries prowess of its own. Cast three cheap spells before combat and a connecting hit is not four damage, it is four bodies that will all grow the next time you empty your hand. The design tension is entirely in the fragility of the vessel: a 1/1 with trample that has to survive to combat and actually land damage before any of this matters. That is the price for an engine that scales with a spellslinger deck's natural rhythm rather than asking for a dedicated combo. Jeskai as a color identity has long promised "cast spells, win with the leftovers," and most attempts leaned on burn or a single big finisher. This one routes the whole plan through the red zone, which is a genuinely different axis: the reward for casting is not damage to the face but a widening board that keeps the prowess triggers compounding. Trample is the quiet load-bearing keyword here, since it lets excess damage spill past a chump onto the player, and combat damage to a player is what the token trigger reads. Miss the attack step and the whole apparatus does nothing.
