I used to play this game until the last update. It's actually so bad and the game is so confusing, they added that weird notebook(unnecessary), you have to basically re-log the whole game just to switch between groups(unnecessary), you can't use other group's cards to level up your main group and loading the game takes an unnecessary eternity, don't download this game, it's just a waste of space in your device, use it to download a game worthy of your cellphone space.
