Great game guys, nice pice of work. Few things that you might want to consider are: more ways of getting cards (for example larger boosters for non gold - maybe pvp points); PvE content (but you know this already - for example random encounter +/- 2 or 1 level from player level), IA seems to make mistakes when shield type buffs are played. I will write more when something will come up to my mind.
