Help stopping a shadows deck

By Captain Wesker, in 4. AGoT Deck Construction

I'm running your basic run-of-the-mill dragon deck (Ya know, Dany and the 3 dragons, all QoD of course) and their various supports and heavily using ambush and running Heir to the Iron Throne. For awhile I've been dominating my circle of friends in melee until one day, my one rival unleashed his Asshai Shadows deck, and it DESTROYED ME! He basically used a combination of Wicked Seductress (RoR), Margaery Tyrell (TftRK), the Black Cells (TftRK) and Sister of Truth (KotStorm) to infintely trigger them to kneel and/or blank all my dragons. Not only is this happening to me constantly, but I also have to deal with two other players trying to destroy me. Basically I'm looking for good anti-shadow cards to put in my deck. All I've got so far is The King's Law plot card.
