Quote from LostCondottiereI've been cycling inbetween 2 Inquisition and 2 Celestial Purge in my board and haven't come to a definitive answer. I feel the Inquisitions can work in tandem with Duress, but I'm not quite sure. Purge is a hard card to give up, especially if All in Red starts burning it's way through standard. I'll keep you updated.
Quote from LostCondottiereLike Lewis said, Pithing Needle is a bit too narrow to have much of a lasting effect and is weak to Oblivion Ring. Needle is not the answer for this deck.
