Grand Arbiter Augustin IV (SLD-1483) is a legendary Human Advisor creature in the Secret Lair Drop set. It reduces the generic cost of white and blue spells you cast by {1} while increasing opponents' spells' generic cost by {1}, effectively taxing opposing plays and accelerating your own. Its two-way cost-modification makes it a linchpin for control or tempo shells that rely on blue-white interaction and mana denial.
