Here's something I worked up for a Lannister deck that seems like a lot of fun.
Its sort of 'rushy' I guess, but I'm still missing a few cards to add to it that can speed it up. 3x Battle of the Blackwater mostly, and 3x To Be A Lion. Those cards, with lots of Intrigue icons and Lannisport seem like one of the few ways available in LCG to really try and spam extra challenges and power tokens. Not sure how reliable it might be in practice, but I think it might be worth trying.
In the meantime, here's the list I'm working with. Brief summary of some of the ideas built into it below.

Lots of the cards in the deck are really good at either making your opponent suffer for having either of the seasons in play, and when you don't want any at all, grab a Carrion Bird and kill their Raven.
A fun little side-combo built in here is Lion's Gate and Carrion Bird. Hit a card with Renown/Infamy that would have a power on it, give them the Raven trait and then drop a Carrion Bird and put it back in their deck.
You can often hit fast and hard with the right opening draws, giving you great early board position. If you lose steam mid-game and aren't able to close it out quickly this deck is actually pretty well equipped to grind it out for a few turns until you can pull off the win. Again, Lion's Gate and Summer Tax are really useful for this. But you also have some pretty good kill, kneel, and saves with some dupes and bodyguards.
Save Barristan Selmy for well into mid/late game if you can. With the Hound, and lots of strong events you'll benefit greatly from his reshuffle of the discard pile.
Speaking of the Hound. I know 3 copies of him might be a bit much. But he's one of my favorite characters, and I think can definitely be worth is drawback for what he brings. You can let him die and play him again later as he only ever goes to the discard pile. Making him Deadly with I'm Writ You Small and giving him an Intrigue icon with Devious Intentions is a lot of fun too.
Lancel and Jhabalar are both good candidates for Devious Intentions as well. They both become Tricon characters, and are also both Lord's so I can slap a Bodyguard on them to help them stick around to make use of infamy and the +1 Strength bonus.
Thoughts, comments, criticisms? I'd like to know what people think of really going for the rush with the Epic Battle cards and some standing tech to make sure I have strong characters still available by the Dominance phase to take advantage.
