Collectible Card Game Headquarters

I wanted to realize the dual lands: after the problem of coding it, I also wanted to give the a proper (and also pretty cool) frame, something LIKE this http://magiccards.info/scans/en/me4/249.jpg. Now, I found the card frames, they're in "Data_Core\DATA_CORE\DATA_ALL_PLATFORMS\ART_ASSETS\TEXTURES\CARD_FRAMES", after realize my dual lands frame, how can I "insert" them in the game, I mean... I must edit some string files don't know exactly where, at least I think...

Any help?

Nobody has a clue about how to do that, yet. The association between card and frame could be in an encoded LOL file, or hard-coded in the executable, one sure thing is that it can't be found in an easy-to-edit place.
