Arcane Laboratory (USG 60) is an uncommon blue enchantment from Urza's Saga that restricts players' spellcasting. Its effect prevents each player from casting more than one spell each turn, including spells that are countered or the Laboratory itself when it resolves. This card is typically used to slow fast combo or storm strategies by imposing a strict per-turn casting limit.
