UR Aggro is a fast, spell-triggered tempo deck, so Authority of the Consuls is excellent, both slowing their creature curve by making them enter tapped and gaining us life against a low-toughness swarm. Lodestone Needle and Pinnacle Starcage remain great against their cheap creature base. Cut slower, reactive cards like Dusk Rose Reliquary and Candy Trail that don't affect the board quickly enough against this aggressive clock.
