{1}{B/R}: Switch a Killbot or Mary O'Kill in your hand with one on the battlefield. (If a creature is tapped, the switched creature is tapped. The same is true for untapped, attacking, blocking, enchanted, equipped, and targeted. Any counters on a creature are on the switched creature instead.)

    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!

  • WotCJan 19, 2018

    Killbot is a creature type. There are several Killbots in the Unstable set.
