Najal, the Storm Runner

Two abilities pull in opposite directions here, and reconciling them is what makes the card interesting. Casting sorceries as though they had flash collapses the wall between your development turn and your reactive turn: a board wipe, a big draw spell, a tempo-swing sorcery, all now holdable through the opponent's turn or dropped in response to their play. That alone rewards a spellslinger shell that would rather bluff a counterspell than tap out. But the second ability wants the opposite posture, because it only pays off when you swing in with the 5/4 body and pay the tax before knowing what you will find. The copy trigger is delayed, not immediate: it waits for your next instant or sorcery this turn, then duplicates it with the option to redirect targets, so the attack becomes a commitment to cast something worth doubling. String them together and the flash-enabled sorcery you were holding becomes the spell that gets copied, which means the same card that lets you play defense also lets you weaponize a combat step into a doubled burn spell or twinned removal. It asks a durdle-leaning color pair to enter combat to unlock its best turns, and that friction between wanting to hold up mana and needing to attack is exactly what keeps a five-mana copy engine from running away with the game.
