Run CBN characters/enhs such as Naaman and Nergashalazer with their respective horses to interrupt the armor's immunity; use Gam's Speech or Kinsmen's Agreement to get rid of one of the armor pieces to put a "chink" in the armor (i.e., negate/discard Helmet then use Martyr or Falling Away then AotL); use regardless of protection enhs such as Stone of Thebez (on a Canaanite woman, when possible), and the upcoming Wicked lost soul.
All of these strategies, and others, have worked quite well for me against an AoG offense.
