WIth the incoming tidal wave of Lannister (hyper? uber?) kneel and intrigue decks, I've found myself considering what the environment is going to look like in response. First Snow of Winter and Search and Detain are secondary considerations as well.
As far as decks, I'm thinking Stark Siege and some Greyjoy decks, with their focus on (low-cost) characters, will fade a bit. Kneel will be rough on them. Greyjoy will probably have a rough time choking out Lannister's gold also, although First Snow of Winter might help with that if the gold characters maintain/increase in popularity. Along those lines, I'm thinking Targ burn might have a bit of a resurgence, as it's a reliable way to get rid of Lannister's characters and Dothraki can flood the board pretty nicely. Maybe Baratheon Rush could be a good answer for Lanni as well.
With FSoW back and GG still lurking, along with plenty of other bounce, I'm guessing Rule by Decree will become more popular, and perhaps even Fear of Winter in combination. Cannot be Bribed, Cannot be Bought is a pretty obvious anti-kneel tech; heck maybe even Distinct Mastery will see more play.
What do you folks think?
