The low rating is entirely ridiculous. Easy learning curve with a decently high skill ceiling. There's constructed in which you need good cards, there's arena to obtain these good cards (get decently good at this, and you'll never have to pay for anything), there's battlegrounds (which i haven't put down since its inception), solo adventures and Duels which i haven't even tried yet because I'm still so into the battlegrounds part of the game. If anything, just download it for the battlegrounds.
