Too hard for me and not necessarily my type of genre. 4 star though because I'm sure that's my specific slant and not a true indictment of the actual game. 2 star if I voted without that consideration.
My first play through I lost because I ran out of cards. I had a full table of monsters ready to go and I was scratching my head. The second play I realized I was supposed to attack the opponent when he was undefended. Oops! 5 star. Very fun.
