As of right now the cards are too big to cast downward so when you pull one up and try and aim down you just cant do it and you cant see the creatures beneath you that are attacking you because the cards are so big they take up most of the screen I would suggest moving the cards to left or right-hand side and making them smaller since nothing really ever attacks on the left and right hand side and the phone is usually bigger on that side
