Pay to win

The game is decent and it is addictive. Ive been playing for a couple months now and it is getting to the point Im going to quit. Seems any of the archwitches you fight you need to pay for the higher end cards or you never win. And even if you do pay theres no guarantee youll get those cards.
To recap, it is fun but if you dont like to spend money, it is going to be frustrating and take a while to get to a point where you are doing great.
