Just some thougths/suggestions:
1. Why the weird numbers? I mean, 29 PWR, 47 HP? These strange numbers make really HARD to calculate damage and so. It isn't player-friendly, not a single bit.
2. Why I can't buy a lower-tier basic pack when I level up? I think there is no harm allowing that.
3. About the cards design #1. It would be better to have the mana cost of the card at the top of it. Why? Because is easier to the user to find it.
4. About the cards design #2. Why the spells have the lvl set to MAX? They are not an ally, it would be neater just to remove the "MAX" label and just left the type of the spell alone, it looks weird the first time you look at them.
5. The art. Just WOW, the art is AWESOME, I mean, look at that heroes, the first time I saw my hero's image (I took Brienne) just after finishing the tutorial, there, in fullscreen mode, I was amazed, the art is GREAT.
Keep the good work, this game has so much potential!
