heres an example:
I use old nan (http://www.cardgamed...y_17_192384.jpg) to give Eddard the house bolton trait. then I attach bloody scourge (http://www.cardgamed...ry_73_82487.jpg) to him. what happens next phase when eddard loses the bolton trait? I suppose he also loses the attachment, which is no longer legal yes?
while we're at it is it possible for a stark player to gain control (lets say with reek or dubious loyalty) of a character that says house X only?
