I'm not sure what the thought process was behind this one. Most card battlers I've played at least have fun animations, things happening on screen, this was so unbelievably dull. Just click a villains face to challenge them, go in to a battle on a beige background, where the cards have no amination to attack besides moving a bit.
It wasn't too terribly hard to figure out, and I won my first five battles, but it was just so incredibly boring that I dropped it. I even went online to check and see if anything happened if you beat the game and literally nothing changed. Such a strange entry in an otherwise amazing series. I'm not sure whose idea this was.
