I originally posted this over at BGG, but I thought I'd share it here, too.

I built this deck and played it twice with a friend last night. In the first game, we used mirror plot decks (just the plots from Lords of Winter), but the lack of a reset in such a military-heavy environment led to unstoppable momentum. So the second game, we swapped out "Family, Honor, Duty," for "Valar Morghulis" (if you only have one copy of the Core Set, Wildfire Assault will also serve"). The second game was much more balanced, with the resets keeping the board even and keeping us from overextending. The score wound up being very close: in the final round, my opponent got 14 power, but couldn't close the deal, and I swung back, winning 15-12. It was a really fun way to play, and playing from a single deck made it feel much more like a self-contained boardgame (ala Race for the Galaxy) than a CCG/LCG.

After posting the deck list, someone on BGG asked if there were any 120 or 140 card deck lists for 3 or 4 players. So I built two 20-card "expansions" out of cards from "A Time of Ravens" and "Defenders of the North" that can be combined with the original 100-card deck to increase the number of possible players. I've posted those below:
