Awesome potential, but litterely nothing to do on the game after (15 wins a day) for tiny rewards, unless of course you spend money on overly priced packs. It's definitely a pay to play game, and that's fine (but gets boring fast with nothing to do). You cannot trade cards with friends, they say because people would just redownload the game. However a leveling system or something could have been added to prevent that in my opinion, but then you wouldn't spend as much money so. Shuffling stinks.
