Used to be great :(

I used to give this game 5 stars. Not anymore. They screw up balance each time they add a new card. Well, its kind of expected and they fix it after a month or two. But! 90% of people use Hog and about 60% skeleton army (while there is a hundred of other cards) and developers do not do anything to fix those cards. These cards might be not so powerful themselves, but they are used in combination. In well known combinations! When almost everyone uses same 1-2 combination to win a game, its not so much fun.
Rebalance it and keep your hands away!
Also, the lack of "ban" button, when you play with a random ally really disappoints.
