Boon of Boseiju⁣ - Kamigawa: Neon Dynasty⁣ (Uncommon)⁣ [176]

Boon of Boseiju is a green instant from Kamigawa: Neon Dynasty that gives a target creature a boost of +X/+X until the end of turn, where X equals the highest mana value of your permanents. This can turn a creature into a significant threat, especially in decks that ramp into larger permanents, and it also untaps the creature, allowing for immediate combat or blocking. It's a handy option for aggressive strategies or those looking to defend effectively while applying pressure.
