Rule of Law (M20 35, Uncommon) is a white enchantment from Core Set 2020 that enforces a strict casting limit. Each player can cast no more than one spell each turn while it’s on the battlefield. It functions as a control or prison piece that slows down combo and multiple-spell strategies, making it useful in stax or tempo builds.
