Terrible Card Store

The gameplay is awesome, and I love the theme. Ive managed to get to level five, and just got my first "rare" reward card. Oops, I cant use it with my character. And because you cant sell back cards you dont want, I just got screwed. Thanks for the wasted hours of gameplay! Same problem with buying boosters in-game? I think I got almost all cards that work, but I dont know if that was luck. I understand making it hard for players to progress without paying, but this is ridiculous. Dont screw me with cards that dont work and I cant dump. (even if I could only sell them back for a reduced price, at least I get something.)

There is one thing I can dump. The Cabals app...
