I've given you 10, you can choose 8 according to your play style, Though if you are going to play in elo i would advise you use Montana, they are cheaper.
Also what recommendations do you have for a deck as I have every character under at least 2.500 clintz and am thinking of selling my whole collection and buy 8 good cards from each clan. Is this a good idea or should I stick with what I've got ???
