It runs locally, is infinitely random but displays the same across all devices running it
Figured on monkeying with it to display decks - a quick mock up of it: http://gandalfpc.great-site.net/indexV2.html
Will add the display to my signature if I finish it up, probably want to do a mix between the two and need to do something so it can handle lots of decks and avoids repeats...
Feel free to grab the script and play around with it
