Fell

For most of the game's history, unconditional creature removal at two mana came with a leash: Doom Blade skipped black creatures, Terror spared artifacts and black things, Ultimate Price hit only monocolored, Go for the Throat still exempts artifacts. The design instinct was that killing anything, no questions asked, for two mana was a rate worth taxing with a rider. This one drops the rider entirely. Destroy target creature, no color exclusion, no artifact loophole, no counter left behind. The only cost is the color commitment and the sorcery timing, which is the real balancing lever here: sorcery speed means it cannot answer a combat trick, cannot be held up in response to an attack, and forces the caster to spend the removal on their own turn against whatever is already on the board. That timing restriction is what modern design uses in place of a target clause: rather than narrowing what the spell can hit, it narrows when the spell can be cast, trading the tactical flexibility of an instant for a clean, comprehensive answer. It is the endpoint of a long line of black two-mana kill spells slowly shedding their conditions, and it lands on the plainest version of the effect: two mana, dead creature, and the only thing you give up is the ability to do it on someone else's turn.
