I have trimmed or colored the borders of quite a few decks...
first, it's this standard RWS that was enclosed in a book.. you had to pull out the cards out of the cardboard.. so what was left was a nasty border with those little things sticking out (that were attached to the cardboard..) ah, I don't know how to explain it, even in my native language, but anyway, here it's how it looks like after the trim+corner cutted

second, Chrysalis
http://imgur.com/a/5tdol gilded edges.. I like it
third, Deviant Moon
http://imgur.com/a/XSGtW also only edges.. Dark brown with a sheen.. better than I expected, since I thought it was gonna clash with the brown of the cards...
fourth,
http://imgur.com/a/pdi3t Hidden Realm.. This came out so beautiful.. Lavender-ish edges that match up nicely with the silver/grey back of the cards..
fifth, Illuminati, the edition without gilded edges and with a thin black border around pictures

sixth, Ludy Lescot, same as Illuminati, blackened the edges.. But sadly I don't have the pictures, maybe I'll ad them later (I don't have the cards nearby..)
seventh, Mary-El.. I completely cut all the borders, rounded the corners, written the title of the card with a golden pen, and then blackened the edges. I kind of regret the last step, I'm not sure it's better this way, especially since I created a very thin, but still bothersome black border around the pictures.. all in all still glad I've done it

and eighth, last one for now is also my fav edit of the deck, Night Sun
http://imgur.com/a/G77dM I've cut the borders which made the cards really small and therefore perfect for my tiny hands.. gilded the edges and the shade of gold is PERFECT for the back of the cards (and the front).. rounded the corners, too, of course... in short, LOVE IT
