Well, you didn't understand what I meant! If you look carefully at the mastery rank requiments you will notice that there are cars that the rank required in challenge 15 is less than pro (halfway pro more or less). Ford Focus RS is an example of what I am talking about. Some other cards require full pro to enter the challenge and even then you need triple boosters to win.
