Good game, but the AI on the 2nd level doesn't seem right, it places way to many troops, that or they get way better cards and many more cards than the player does.
Figured out how to get to 15...now I'm stuck and keep trying different combo's of the skills and no luck getting past those 3 towers. It seems like I don't have enough fire power or mana to keep going.
When the game is over, use History and you can look back to see where they got all of their armies.
