I am a player who currently buys 1-2 chapter packs of each chapter. In doing so, there are usually some cards that I want a third copy of, and others that I don't want more than one of (or sometimes, don't want any of). I build all of the houses, and maintain my card collection for my entire collection, so when there is a mechanic that I don't like (e.g. the Reinforcements), I don't want any of those cards.
That being said, is there anyone out there (preferably on the West Coast, or especially in California) that would be willing to form an ongoing trade relationship, occasionally splitting a third chapter pack, or something like that?
