I can definitely see Jonas' point here, as I doubt we will see another copy of this card. However, if the card is going to be added, I would put it on the main list for two reasons: 1) We know from the seller's listing that this error exists for other players, and so if Juan appeared more than once on the printing sheet, then more than 1 copy probably does exist; and 2) We know that it was distributed in a pack. I don't know anything about that Foot Locker card, but unless someone saw it pulled, I believe there should be a reasonable amount of doubt about its origins and legitimacy. That doubt, plus the card's general weirdness, keeps the Foot Locker card in a totally unique category for me.
