I remember there being a rule that you had to write your name and birthday on the card or you couldn't play it. Am I wrong? That would really lower the cards value :/ I actually saw one these once with the owners name writen on it >.<
IIRC, it was legal for a short time after it came out. I remember using it at an Unlimited Tournament on my birthday, but I still didn't win . I just brought my birth certificate copy with me and all went well.
