Grand Arbiter Augustin IV (DIS-112) is a legendary Human Advisor creature from the Dissension expansion. It reduces the generic mana cost of white and blue spells you cast and increases the generic cost of spells your opponents cast. Its cost-altering static effects primarily affect the generic portion of mana costs, making it a tax-and-accelerate piece for control or tempo strategies.
