This is my favorite phone or tablet game! I mostly enjoy the collecting and trading of cards in the game. That does not mean the league games are not fun. They are extremely unique in that with hundreds of cards to choose from deck building is as intense or as simple to put together. With all the abilities on the cards strategy is all over the place in a good way. The creators of the game are very active in listening to players from problems to suggestions!I can't stress that last point enough:)
