Curse Artifact

Most aura-based answers commit fully on resolution: enchant the thing, change its rules, done. This one installs a clock instead, charging the artifact's controller 2 damage every upkeep until they give up the permanent, the kind of recurring tax that defined black's relationship to artifacts in an era when artifacts were the durable engines the color pie most worried about. The friction is doing the balancing work. At four mana the card is slow, and it never actually destroys anything by itself; it just makes keeping the artifact more expensive than it is worth, turn after turn. That puts the decision in the opponent's hands, an unusual posture for black removal and a tell about how the early game treated artifacts as machines worth grinding away rather than blowing up. The sacrifice clause also routes around indestructibility and regeneration entirely, since the controller is the one choosing to let it go. The catch is that the 2 damage is dealt, not lost directly, so it can be prevented or dodged, and the controller can simply eat the damage indefinitely if their life total allows. It is a narrow, conditional answer that asks for patience and rewards a position where the opponent cannot comfortably absorb the recurring damage, the kind of measured artifact hate that later sets would replace with cleaner instant-speed destruction.
