I found and recently purchased a 3D Lenticular card of said Pokemon in the subject. Thought it was really cool and wanted to add it to my collection. Seems to have been released in Japan at the time of the Deoxys film (2004).
However, I can’t find any information on it’s exact release date, how it was released/distributed and what is technically the name of the card. Only snippet I have is the seller said it came from an infants magazine in Japan similar to Corocoro magazines(?). But, they weren’t entirely sure themselves. There is some Japanese on the card, but I can’t translate that which could definitely help in some way.
I’ll post some images below, but any help would be appreciated. Thanks!
It’s an unnumbered bonus card from the dark, so in a confusing way it isn’t on the deck list on the page, even though it’s the first card in your the pack
