I first found this game on YouTube and thought it was silly at the time. However, I still downloaded the game and I was amazed with all the thousands of cards and the unique system they have made. The adds may seem bad at first, but it is a free game and they're never in your face; besides, you can still play the game to its fullest without watching adds. All in all, I wish this game was ported to PC and given a chance to grow as this is something you don't wanna miss out on....
