Demon's Grasp

A -5/-5 kills nearly everything a creature deck can field, and it does the killing by shrinking rather than destroying: indestructible is no defense against a toughness that drops below one. That reach is the appeal. The tax is the rest of the card. At sorcery speed and a full five mana, it surrenders every trait that makes black removal feared (the instant-speed ambush, the cheap one-for-one) in exchange for a near-guarantee that the biggest creature on the board simply dies. This is removal built for the slow lane, for a deck that can afford to sit on a threat until it has the mana to answer it cleanly, where deleting an opposing bomb for five is a fair trade rather than a tempo collapse. It sits among the black common-rarity removal calibrated for filling out a set's answer suite rather than earning a constructed slot: the effect is dependable, but the price asks too much of any deck running a clock. The reach sells it and the timing taxes it, and a designer pricing the next reliable -X/-X is always negotiating how much certainty a slow color is allowed to buy.
