Currently, no tool exists to assist you in doing card modifications for the xbox360 version of this game. In order to mod the card deck, you must manually use a hex editor and find the offsets for each character, the card values and then assign individual cards one by one; which is quite a challenge for a beginner, so it would be useful if you know your way around hexadecimal programming. I would make a tool for the xbox360 version if I knew C++ but unfortunately, someone else will have to do that.
