Scent of Cinder

A burn spell that taxes your hand instead of your mana, and that inversion is the whole design. Most red damage scales off mana value: bigger spells cost more, and the rate is fixed at cast. Here the cost is two, full stop, and the payload is whatever red surplus you happen to be holding. Each red card revealed is a point of damage, so the spell turns dead-in-hand red cards (the second copy of a creature you do not need, a removal spell with no good target, a burn spell you have no time to cast) into reach. That makes it a release valve for a hand that has overcommitted to its color, converting card quantity directly into face damage or a removal answer at the exact moment you have cards to spare. What contains the ceiling is the reveal itself: you only show the cards, you never spend them, and only red cards count, so lands and off-color spells add nothing. The payoff lives and dies with how monochromatically red your deck is built. A deck that splashes red gets a glorified Shock; a deck drowning in red gets a finisher. It is a parasitic payoff in the cleanest sense, rewarding the kind of color-saturated construction that usually punishes you with flooded, redundant hands, then handing that redundancy back as damage to any target.
