Took this deck to GNK to play just for fun and did not put high hopes, but it performed quite good. Lost only once to the undefeated winner, against Tyrell/KoS. Won against Targ/Lion, Martell/Fealty, Martell/Lion, Stark/Fealty. This deck was real fun to play and very satisfactory to take away all the monies from opponents. Especially hitting Wraiths in their midst against Pentoshi, leaving them with 7 gold and 2 reserve.
From card deck I would now remove Master Chains - it was last minute idea, but it did not do any good, as NW is quite resistant to attachments and was hard to get combo House Maester+Maester chain (forgot that Aemon is "no attachments" too, so thats some less targets) maybe change to Hand Judgement. Everything else was doing good. Craven and White Tree were doing so much job, got some hits with Watcher on the walls, and if not, even the danger of it was mostly enough.
