You can always print them, after building them in templating programs (full color, if you want to, with pictures and everything), and simply sleeve a regular card up with the printed front, so it's basically the same size (a sheet of paper is not THAT big anyway) of a card and fits in a deck. Mind, though, that there ARE legality issues with doing that kind of stuff, but I think that as long as you're having your fun with a group of friends and nothing else, it's all good. Just don't post said templated cards on the web, or anything, since it's copyright infringement, which is why we go text-only on this site.
PS: We might be able to get a new DC set coded into GCCG after we get it done, so you can ALSO play "online" with the "nerw" cards.
