My friends and I have been getting into Arkham Horror a lot more lately and so I decided to add to the game by buying some of the expansions. We were going in order so I picked up Curse of the Dark Pharaoh and just recently Dunwich Horror. We've just been combining decks but I feel the decks are getting too large. I was wondering what to do about this.
Would it be better to play with the base cards plus a single expansion? Or should I look through each expansion and take certain cards out to make a "master" deck for locations, arkham, mythos, and other world decks which include every expansion I have? Also, would it be a bad idea to play with every expansion active at one time?
