Dread Specter

The combat trigger is the entire card, and it is a deterrent more than a weapon: any nonblack creature that touches this Specter in combat dies at end of combat, regardless of how the damage math shakes out. That turns the body into a poison pill in the red zone. An opponent can crash through with a fat attacker and trade their good creature for a 2/2, or they can route around it and let it sit. Either way the threat does the work the stats never could. The color restriction is the lever that makes the rate sane: against a black deck the trigger reads as blank, so the card swings hard along the color axis instead of being a flat answer to everything. That clause is also a flavor seam from a set built around its color tensions, where black's creatures are explicitly meant to brush past their own kind. The destruction is the brute-force kind, not a damage-based pump or a tap, so indestructible blockers and regeneration are the wrinkles that defeat it rather than toughness math. It is a wall that punishes contact, an early experiment in a deterrent creature whose value is measured in the attacks it discourages rather than the bodies it actually removes.
