I've only played around with this for a second, but a couple of things jumped out at me.
#1 It would be helpful to be able to navigate by letter, in addition to the other options. Clicking blindly through the numbers along the bottom trying to get to "Js" can kinda be a pain, especially as the list grows.
#2 Are there action point and second wind cards for this style yet?
#3 Any chance that you could change the page generated so that the cards had a black border (about 15px) and shared edges? The black border helps hide a host of problems including sizing issues, and sharing edges means that you've got less cutting to do.
