The only thing holding the card back is that the art doesn’t have any Pokemon in it . And, AFAICT, it’s not as rare as something like the English Championship Arena, which has low triple digit number of copies in existence (and Celebi and Mew in the art!) and is still pretty affordable.
The only sources I have are: on the thread with the master list of rarest cards, someone suggested PCL be put on the list. And someone else responded that it shouldn’t be put on the list because there were way more than 1000 copies released. I don’t know what that’s person source is, but they seemed pretty confident and it would be a weird thing to lie about, so I trust that until I learn otherwise.
And there’s also just the market presence of the card – it’s much more available. That doesn’t necessarily mean it’s less rare, but it suggests that it likely is.
I just want to say the full art trainer/character cards from Cosmic Eclipse. That Pikachu character card is straight-up Pokemon, I love it. (can’t seem to figure out how to upload pictures)
Just awesome how many japanese cards are showing up. also in for the vending serie cards or ex era artwork cards (the not ex and goldstars are still affordable)
