Choice Band

Choice Band turns a physical attacker into a one-shot wrecking ball. The ×1.5 Attack boost is one of the biggest single-stat buffs in the game; the cost is move-lock — once you click Earthquake, Earthquake is your only option until the holder leaves the field. Best on Pokémon with strong STAB coverage or partners that can pivot it out (U-turn, Volt Switch, Baton Pass).
