Azorius Control wants to counter or sweep your threats with No More Lies, Supreme Verdict, and Temporary Lockdown, so Surrak, Elusive Hunter can't be countered and punishes their removal-heavy approach by drawing cards whenever they target your other creatures. Elesh Norn, Mother of Machines doubles up your own Cavalier of Thorns and Storm the Festival value, helping you rebuild faster after a sweeper. The Stone Brain can proactively exile a problematic The Wandering Emperor or The Theorist, Jace Beleren from their deck entirely. Ulvenwald Oddity and the single Polukranos Reborn are cut since they're too passive against a deck that will simply Supreme Verdict away small-impact creatures.
