Mary O'Kill (UST 138) is a legendary creature card from Unstable that is a Legendary Human Villain in black and red. It has an activated ability for {1}{B/R} that swaps Mary O'Kill or a Killbot in your hand with one on the battlefield, transferring all tapped/untapped status, attachments, counters, and targeting. The effect enables tricksy creature substitutions for tempo, protection, or to reuse enter-the-battlefield or hand-trigger effects.
