1. Often freezes in the middle of game play requiring app restart. By the time you re-enter the game, the entire situation is changed. 2. The card draw randomization is flawed. There's no way a 60 card deck with 24 lands starts with 2 lands and pulls ZERO lands the entire game, 4 games in a row. 3. Quickly turning into: free to play, pay to win; the standard card rewards aren't competitive with the buy packages. 4. It makes no sense that the daily win quest and the weekly quest are both 15.
