Metamorphic Alteration

Most copy effects in blue point inward: clone the best creature on the board and take its stats and abilities for your side. This one points the other way. It rewrites any creature into a copy of a creature you choose, and the chosen creature can be a token, a 1/1, or some defanged body you sandbagged for exactly this purpose. The result is a removal spell wearing copy-magic clothes: turn the opposing bomb into a vanilla bear, or erase whatever made a creature dangerous by making it identical to one that does nothing. The Aura form is the price. It has no flash, so the answer only fires at sorcery speed; it sits on the battlefield afterward, vulnerable to enchantment removal; and the moment it leaves, the enchanted creature snaps back to itself. This is not exile or destruction but a temporary identity swap that holds only as long as the Aura does. Pointing it at your own board opens the upside lane: stamp your best creature onto a spare token, or assemble a squad of copies of whatever matters most. What keeps the card honest is that it can address almost any creature on either side, but never permanently and never at a profit in card count. You spend a card to neutralize a card, and you have to keep the Aura alive to keep the answer in place, which makes it an answer that never fully finishes its own job.
