I call it Kozmo's Card Mod, because i don't want to attribute some name to it, i didn't work on it much.
What did i do on it then?
I wanted to do some nice stuff, but the compression (I think) of the file made it impossible to work much on the original cards, and artifacts were starting to appear.
I only inverted the colors, and then i added a 'Great Milenko' on the back of the card.
It works for me, and if you want, you can make it work for you too :)
