Oracle text

For all intents and purposes, the exchanged card is taking the place of the original card. Whatever its doing, the state it’s in, whatever’s attached to it—all of it stays the same. It’s as if Mary O’Kill or one of the Killbots pulls off a mask to reveal they were actually the other one all along. Diabolical!
