I have been trying to play the game for about 2 months. I've spent close to $100 so far and am still waiting for days to unlock more storylines. Have not received any high-level cards in over a month or any significant free boosters. Items cost over 200 gems each you'll have to buy some everyday if you expect to advance anytime soon. VERY GREEDY game..not worth the time or money. Also, there is no way to watch ads for free boosters.. This is a very disappointing game.
