Rule of Law (MRD-19 foil) is a white enchantment from the Mirrodin expansion. Its continuous effect limits each player to casting no more than one spell per turn. This restriction shapes deck construction and play patterns by severely slowing combo lines and favoring decks that rely on incremental plays or nonspells.
