Induce Despair

Most -X/-X removal scales off something you spend: mana sunk into an X spell, creatures fed to a sacrifice outlet, life paid. This one scales off something you merely show. The kill is as big as the heaviest creature you are willing to flash from hand, and the elegant part of the bargain is that you keep that creature afterward: the additional cost is a reveal, not a discard, so the spell turns your top end into a kill spell without ever subtracting it from your grip. The cost is paid in information instead. Your opponent learns exactly what is sitting in your hand, which makes this best fueled by the kind of bomb you are happy to broadcast because there is no answer to it anyway. The ideal target for the reveal is a fat creature you cannot cast yet: an eight-drop stranded in your opening hand does nothing for your board but flips three mana into a -8/-8 swing, so the spell rewards exactly the awkward draws (heavy hand, light mana) that usually hurt. The tension runs the other direction too. A hand full of one-drops shrinks the effect toward nothing, and a grip empty of creatures leaves you unable to cast it at all, so its reliability is borrowed from the rest of your hand rather than from anything printed on the card itself. That is the unusual card-economy at the core of it: removal whose size is dictated by your deck's curve, and whose price is your opponent's foreknowledge rather than any resource you lose.
