Karmic Justice
Most deterrents threaten to punish your opponent for attacking; this one threatens to punish them for using their own cards correctly. The trick is in what it protects: noncreature permanents only. Enchantments, artifacts, lands, planeswalkers, the soft targets that other formats of removal exist to pick off get a bodyguard who answers a Disenchant or a Stone Rain or a Vindicate by killing something in return. The retaliation is broad where the trigger is narrow: any permanent the offending opponent controls, your choice, so the threat scales with their board rather than the value of what they destroyed. That asymmetry is the whole deterrent. A control deck that lives on its enchantments and artifacts suddenly makes targeted disruption a trade rather than a clean answer, and a well-built one with a fragile, irreplaceable noncreature shell turns this into a quiet insurance policy that taxes every piece of removal aimed its way. It does nothing against sweepers that destroy creatures, nothing against bounce or exile, nothing against a sacrifice you make yourself: the wording demands an opponent's spell or ability, and demands destruction specifically. Within that window it is a piece of political and structural defense, the kind of card that shapes how an opponent sequences their answers more than it ever needs to fire.
