This game isn't very good, honestly. The art is bad and the gameplay is poor. The only reason I'd ever play this is because I had to win a card by doing so. 4.15 stars? Really? Who are we kidding, this game pretty much sucks. There just isn't anything fun about it.
The AI is pants, and oftentimes makes very blatent errors, such as not blocking when it would die, blocking the wrong creatures, ect. There also seems to be a bug occaisionally when you have a lot of creatures out, when it won't let you attack with a creature randomly or will end your attack phase early. The creature isn't grayed out, but clicking on it does nothing and it is as if it had attacked - it can't block either.
