If I could give no stars I would. Only way you can get game winning boosters is to buy them. The system does not equally match you, so where you could have just purchased a booster, you can lose that booster to someone whose booster is levels below you. Now, when you use a lower booster you get beaten badly, so never a truly fair match up and I'm not paying for anything to still lose what I just purchased no way. Fix the matching and ooooh the clock... time stands still for your opponents only.
