Grand Aubiter Augustin IV by EThom759

Format: Commander

Commander: Grand Arbiter Augustin IV

Bracket: 3

Deck overview

Grand Arbiter Augustin IV leads a stax/pillow-fort shell, but the deck is actually built around 30 Persistent Petitioners as its hidden commander. GAAIV discounts every white/blue spell, most importantly turning each Petitioner into a one-blue investment, while Propaganda, Ghostly Prison, Authority of the Consuls, and Dissipation Field stall combat. The primary win is mass-milling opponents: Drumbellower untaps the Advisor army during every opponent's untap step, and Intruder Alarm chains extra untap waves as more Petitioners or token creatures enter. Secondary paths use High Tide, Mass Appeal, and X-draw spells to find enough Petitioners for a burst turn. The commander never directly wins but is the indispensable tax and mana engine.
