Twinflame

Where most clone effects lock you to a single body, strive turns the mana curve itself into the scaling knob: each target beyond the first tacks on , so the two-mana base is a floor you only pay when copying one creature, and a full board can be doubled for one sorcery-speed swing if you can afford it. The copies arrive with haste and vanish at the next end step, which steers the card away from value-engine builds and toward a precombat alpha strike: cast it before combat on your turn, attack with an unexpected total, then watch the doubles evaporate before they can be answered. The exile clause keeps the math honest, since the tokens never linger to be reused or chump-blocked on the back swing, and the haste is what lets them join the attack the very turn they appear. The bigger payoff comes from copying creatures whose enter-the-battlefield triggers fire on the way in; the body is incidental, the trigger is the prize, and the token still gets one attack before it leaves. It is a spell built for a specific shape of deck: one with creatures worth duplicating and the ramp to strive into multiple targets at once, asking you to spend the main phase you would have spent developing on a single oversized turn instead.
