Rending Flame

Five damage at instant speed reaches a toughness band most burn spells top out below, and it points at planeswalkers as readily as creatures, which is where the extra size earns its cost. That base line would justify the spell on its own; the Spirit clause is the design trick worth noticing. Conditional anti-tribal tech usually gets stapled to cards you only reach for when the field demands them, and the punisher rider does nothing the rest of the time. Here the rider is grafted onto damage that already clears almost anything a fair deck fields, so the hate never costs you anything to include. Against a Spirit shell the spell kills the threat and burns its pilot for two on top, converting a clean trade into a tempo-and-reach swing; against everything else it is simply a large, flexible burn spell that would have been worth casting regardless. The face damage is a flourish layered over a removal effect that was already priced to be worth the cast. What makes the design hold together is that the punisher clause is free carry: the spell is calibrated to pull its weight with the rider switched off, so the tribal answer rides along at no premium. That is a hard balance to strike, since most punisher spells either overprice the effect for the sake of the rider or narrow the target so tightly the card only ever wants to be a specialized answer.
