Erratic Mutation (MMA-42) is a blue instant from Modern Masters that targets a creature. When it resolves you reveal cards from the top of your library until you reveal a nonland card and that creature gets +X/-X until end of turn where X is that card’s mana value. The revealed cards are then placed on the bottom of your library in any order, so the effect is temporary and also interacts with your library ordering.
