My opponent has this deck focusing on Beric Dondarrion, Brotherhood, and power grab. Normally, our decks are evenly matched, and we each win about half of the time. But this Beric deck beats me 5 games out of 6. He keeps his power, he never dies, its ridiculous. Decks I've tried against it:
Stark, Bara Knights, Bara Asshai, Neutral Kill
What decktypes do you think work well against this guy? I know there are certain cards that can take him out (Game of Cyvasse, etc.), but what are some good overall strategies?
