Ive been playing this game for a long time, and Ive struggled lots, like other reviews say, but the only reason why you would lose to a card is because you dont know how to properly defend against it. Every card has its weakness. Also, dont complain about the game if you havent reached arena 4 or 5, because that is when the game is really enjoyable. Sure, chests take a while to open in higher arenas, but dont complain if you havent even been there :/
