Reprobation

Removal that leaves the body on the battlefield asks a different question than removal that kills. Rather than sending the target to the graveyard (where recursion, death triggers, and graveyard payoffs can turn a kill spell into a gift), this Aura hollows the creature out and leaves the husk sitting there: no abilities, no relevant types, a 0/1 that has forgotten it was ever a threat. That distinction matters against exactly the targets fair white decks most fear. A commander that punishes leaving play, a creature with a death trigger, a card that wants to be milled or discarded so it can come back: none of them get to fire when the answer is a shape-change instead of a funeral. The Coward line is the punchline, but the design work is in "loses all abilities and is a Coward creature": it strips indestructible, hexproof-granted-by-self, regeneration, and every activated escape hatch, then locks the stats low enough that the neutered creature cannot even trade. The cost of that clean, trigger-proof answer is that it stays attached. Enchantment removal, a bounce spell, or anything that flickers the enchanted creature hands the abilities and body straight back, so the Aura trades permanence-of-the-kill for reversibility. Its closest kin are the "turn it off rather than destroy it" effects, nearer in spirit to Song of the Dryads than to a burn spell, and it earns its slot precisely in the matchups where the graveyard is the opponent's second hand.
