Actually, I'm sure it's not.
Yesterday, I built a Baratheon Winter Night's Watch deck with all the obvious trimmings: Stannis (Defenders), The Wall, The Stewards agenda, Longclaw, White Ravens, Carrion Birds, Samwell Tarly, and a bunch of Baratheon characters with renown and M/P icons, who, under the influence Stannis, The Stewards, and The Wall, were +1 STR Tricons who didn’t have to kneel to defend.
It worked against a very basic Lannister deck, but it felt sluggish and fragile. Part of this is because I threw absolutely everything that seemed like a moderately good idea in the deck. Including the agenda, in is 70 cards.
I am somewhat restrained by the fact that I have only one copy of each chapter pack, and that won't likely change. So I only have 1 copy of The Wall and 1 copy of King Stannis. I do have two copies of the Core Set and 2 copies of Kings of the Sea, and a single copy of both Princes of the Sun and Lords of Winter.
If any of you could suggest where to trim this deck, I would be greatly appreciative. Sadly, I won't be competing at the Gencon Joust or Melee this year, so you won't be helping me sharpen a blade that will be used against you.
