Too much pay to win. After 2 and something years of playing it I uninstalled it. It just becomes impossible to progress if you don't throw money at it. You hit a pay wall where your progress is stalled and other lower lever players beat you with higher level cards with which you just can't compete with. A lot of smurfs too. You need more than 1000 cards of the same type to max them out, not to mention thousand of resources to level them. Too bad, the game has potential.
