you can choose which card to play by scrolling over them and selecting it. Once they are played they go in order. The cards are quit Low res when they are small and hard to read, once you select them you should be able to read them.
The stats for the enemies are all there and ready-to-wear be displayed... injust didn't get to it. I wanted to be able to click on the enemy to get more info and potentially have weaknesses to certain enemies to add some more strategy but didn't get to it!
Thanks for playing and your feedback, some great ideas!
