Man, everything is good in a certain department. Overall, I like the cleanliness of vrt's and Dragoon's, but I also like the idea of putting ^ up arrows on upgraded cards to make them more obvious. I had trouble telling the difference when I first started. Maybe we could put it at the bottom left of the picture, like in the slots? :3
vrt has a good idea with putting the card type right below the name. Like with upgraded cards, I really had no idea what the symbols meant in the beginning (partly because I'm stupid and skimmed over the tutorial). But we should still be as newbie-friendly as possible, right? Also, for some reason I like the white borders around his cards, as well as the squareness. I can't tell you why, because I just do for no real reason. I guess I just don't like rounded corners? xD
Quotes are a cool idea, but unnecessary. I wouldn't mind either way.
Looking forward to what's coming! I can't wait for this to be implemented! ^^
