It was 5 star until you took out coop. 5 keys every 12 hrs, can't grind gold so a gold card comes in shop you can't buy it. You can't just play a game with your friends now. I used my first 5 keys, no level was hard at all, now can only play pvp which I can't really get any higher in trophies without a better deck which now how do I upgrade a card that cost 30k?
