Rulings
-
You can activate Mary O’Kill’s ability if it is in your hand.
-
Killbot is a creature type. There are several Killbots in the Unstable set.
-
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!
