Flamehold Grappler

Spell-copying has almost always been a spell you pay for on its own turn: Twincast, Fork, the whole Reverberate lineage sit in hand waiting for a target worth doubling. Stapling that effect to a 3/3 first striker changes the sequencing math entirely. The copy is a delayed trigger keyed to the next spell you cast this turn, which means the body resolves first and the doubling comes free with the tempo you already spent, provided you hold a second spell for the same turn. That "when you cast it" wording matters: the copy is created on cast, so it can duplicate a spell that is countered or fizzles, and you may aim the copy elsewhere for a two-target split. The friction is the same one every copy effect carries, that a copy of nothing is nothing, but here the cost is baked into deck construction rather than a card slot: you are asking a creature to enter and then find something worth its trigger before the turn ends. Get the ordering right and a modest removal spell becomes two, a burn spell splits across two faces, a game-ending sorcery resolves twice. The Jeskai color identity is doing real work, gathering the spell density, the reach, and the willingness to build a turn around a payoff creature that first strike lets survive the crackback.
