Rookie Mistake (M21-66, Foil) is a blue instant from Core Set 2021. It gives one target creature +0/+2 and gives another target creature -2/-0 until end of turn, requiring you to choose two targets when casting. The card is a cheap tempo trick that can save a blocker or finish off a small attacker while simultaneously weakening a different creature.
