Well, title explains it. I got some cards from a friend of mine, but one of em, a Mawile PK, has this '20' written on it with a pen at the right side of 'Call for Family'. This is (unfortunately xD ) not true. It is clearly a legal card and it is easy to tell that the number was added with a pen after the card being printed. But can I still use this card normally? I can use reference of the normal card if needed.
