This game is awful, if I don't have a full 4 bars of wifi I disconnect from the game, and can't reconnect until minutes later after I lost. When I can actually play the game, it's impossible to win, to go up a single arena requires hours upon hours of dealing with toxic players, stupid decks, and an inability to win at all, this game is just luck of the draw, and hope your opponent simply is using a deck with cards that can't compete with your deck. And if you dont get incredibly lucky? OH WELL!
