Not much to contribute competitively yet, just wanted to drop by and say that I'm really enjoying the game so far!
It's a very "classic" feeling card game in a way. My friend and I were playing and very few rules needed to be repeated because everything seemed to build off MTG era templating and mechanics, perhaps with the exception of things like Dominance and Duplicates. Keywords seemed intuitive, it was immediately apparent how great something like Insight is, and the rule book and Learn to Play was good. I think FFG has gotten better at Core Set rulebooks since Netrunner.
I certainly haven't gotten around to every house and combination yet, but I'm thinking about maining Lannisters for a while. Night's Watch was cool, but it kind of felt like playing defense the whole time. Martell also seemed a little... thinly spread? Also consensus seems to be Baratheon and Greyjoy are the powerhouses, but some of the Rh'llor cards seemed a little situational to me. Is that incorrect?
How are people going about building aggro vs. control? Does such a thing as curve really exist when you have a 8 gold set up?
Overall I'm super excited about the game. I assume the Worlds tournament is full, but it would be great to get some pick up games.
