Got a few test games at a local store with my NW fealty deck last monday. Basically demolished Greyjoy Fealty, although skill of pilot was to be taken into consideration.
I've played one match against my girlfriend's Lanni/Rose and I've also played two games against a Lanni/Sun deck based around first snow.
That deck ran many icon removing attachments, paid off, naval superiority, brothel madams. A good choke deck with a bunch of jumpers, of particular note was the Queen's assassin. Quite aggro.
It's a draw.
I conceded one match when he hit 11 Power seeing as I would've had some difficulty climbing back with my 8 power (with no characters to his Tywin, Nymeria and Tyrion), and He's conceded the other to me since we realized he played many attachments on no attachments character (it was late for both of us) but even then I was ahead 10 power to his 5...not bad considering his first turn Naval worked.
Some key plays:
Played For the Watch during his Game of Thrones... we both laughed at how well time that was.
Played Fortified Position on his First Snow Turn, removing his econ advantage from Tywin and reducer chuds. His Tyrion and Tywin were useless and he had no money to pay for both of his Queen Assassins (that he had played in set up) when they returned into his hand. He had barely enough money to pay for one to serve as Military claim.
He was lucky to claim my Watchers on the Walls for Intrigue before every Military challenge he made...each time. It would've cost him Tywin, Jaime and Nymeria.
Managed to pop Sword in Darkness on a chud Military challenge on his turn, the first one.
Some lessons:
Plots with control effects rule over those with econ. As long as I could play one or two characters and have a gold or Fealty standing, I found out I was okay.
I had strong characters out on all First snow turns: Benjen, Will (my mvp), Ranging Party, Alliser, dupes, Jon Snow (yes I've included him in in case I need to switch to an offensive strategy and as int protection for first snow)
I included both Watchers on the Wall and Sword in the Darkness. My reasoning is I can either pop one, or the other as my opponent cannot effectively play trying to counter both unless they are bara and play a ridiculous amount of Seen in Flames.
I ran no Hand's Judgments. Risky against Targ, but I had to cut something...and I'll try to dance around challenges or throw Benjen in there and have a backup in case I lose a character to Dracarys, mainly throw chuds in challenges. With The Wall I'm not too worried about Blood of the Dragon and with the Practice blades, I'm not too scared about Plaza.
I also tested NW Fealty last night and I found a lot of the same things to be true.
I went 1-1 vs Greyjoy Sun, 1-0 vs Greyjoy Fealty and 1-0 vs Lanni LotC (though he had some very obvious play mistakes, from my point of view).
I'd also gone 4-2 on OCTGN, with a loss against Lannister LotC and Targaryen Fealty, and wins against Tyrell Fealty, Tyrell LotC, Stark Stag and Martell Watch on OCTGN. I've changed things a bit since those 2 losses though.
During the 10 games I've played with the deck, I've killed 1. Asha and Theon, 2. Asha and Balon, 3. Euron, 4. Tywin and the Mountain, 5. Khal Drogo and a Braided Warrior, 6. Randyll and a Tyrell Army, 7. Robb Stark a dominance stander and a dupe off of Eddard, and 8. I almost killed Tywin and Jaime, but he had two hand's judgments to my one with The Watcher on the Walls.
Definitely hoping that people continue to test the Watcher.
In the 4 games last night, First Snow was played against me each time, and had virtually no effect on me. I always had at least 1 or 2 ranging parties out and another high cost character by the time they could bring out First Snow. In one game, I had 2 ranging parties and Will along with Aemon, a reducer and an old forest hunter and he still had to play it even though he only had Euron to survive his own first snow. I promptly Watcher'd him that turn haha. Although, in retrospect, I could have just done a heavy military and killed him anyway. Meh.
Old Bear Mormont is the star of the deck, with Benjen a close 2nd. I triggered Old Bear's interrupt 5 times in 4 games. Twice it was on a For the Watch! turn. Turns out people are not all that willing to give up a character that they know is going to lose a challenge, and they'd much prefer just defend all 3 challenges themselves. In one of the games, I did For the Watch! against a Greyjoy deck and he didn't have an intrigue icon. So he had to choose either military or power to throw away, and I had old Bear and Benjen and Will, so he was unable to get anything through anyway, so he just passed. I got intrigue with Will, power with Old Bear and Benjen and then, because of Old Bear's ability, I played a second Ranging Party and then won dominance because of that.
Overall, I'm feeling pretty good about the deck. Raiding longships are a hassle, but I have 3 practice blades and a Longclaw (really wish I could fit two longclaws, but alas, I cannot.). Each loss was close and the wins were huge. The win against Lanni LotC was something like 15 to 3. That game was basically over when Tywin got Watched.
