Invert Polarity

Strategy & Gameplay

This versatile instant from Modern Horizons 3 offers incredible value in any blue-red control or tempo strategy by providing flexible interaction that adapts to your needs. At three mana with two blue and one red, Invert Polarity serves as a hybrid answer to problematic spells your opponents cast, functioning as either a counterspell or a theft effect depending on the coin flip outcome. The flexibility is the real strength here: if you win the flip, you gain control of the target spell and can redirect it toward a new target, potentially turning your opponent's removal spell against their own creatures or forcing their draw spell to fill your hand instead. If you lose the flip, you still get full value by countering the spell entirely, so you're never left with a dead card in hand. This makes Invert Polarity exceptional in interactive matchups where you're playing the control role, as it handles both creature-based spells and non-creature threats effectively. The card slots naturally into UR control, UR tempo, UR murktide variants, and even Izzet Murktide shells in Modern and Legacy formats, where it provides main-deck interaction that scales with your meta. Commander and Oathbreaker players building Izzet spellslinger decks will appreciate the flexibility, and the card's legality across Historic, Timeless, Modern, Legacy, Vintage, and Penny Dreadful formats means it's a worthwhile investment for competitive and casual players alike. Invert Polarity represents exactly the kind of modal efficiency that makes blue-red strategies viable in competitive Magic.
