Chronobot (CMB2-105) is an Artifact Creature — Construct from the Mystery Booster Playtest Cards 2021 set. When it enters the battlefield it switches upkeep steps with a target opponent for as long as it remains on the battlefield, making you the active player during that opponent’s turn while the turn is still considered theirs. Its 2/2 body and low mana cost position it as an early disruptive tempo piece that can alter the timing of upkeep-based effects and interactions.
