Not sure what your criteria are but
Pikachu (BW Promo 77) - Bulbapedia, the community-driven Pokémon encyclopedia (bulbagarden.net) and the Raichu (BW 78) was never released in English despite the original intention to be. I do wonder at times if they ever got printed and could be floating around somewhere…
Idk if these two count, but here’s a couple:
Depending on your definition of “unreleased”
The Daisuki Club was a program that existed in Japan where members could acquire Action Points (AP) by competing in tournaments that would be rewarded with promo cards. A very detailed summary of the Daisuki Club can be found on Pokumon:
[L-P promo set]

Cresselia (045/DPt-P) Darkrai (046/DPt-P)
You can also add protostoise and maybe disco holo base sheet
Do Art Academy cards, that have never been sold by the actual winners, count as “unreleased”? lol
Disco and Cosmos Base set holos
We’ve already seen several prototype cards, but I find this
article quite interesting, explaining their “history” and comparing their design with the final one.
Aren’t these cards’ design and artwork for the phonecards?
They were originally real cards?
What magazine/book is this taken from?
These and the legendary birds artworks are amazing!!
@mika Yep, that’s the post I was getting the pictures from Thank you for linking it
@pfm Prototoise is a good one. But I don’t know if I would add the sheets. Then would also include all the other test print sheets and so on.
@decoypalmette they definitely count. Where did you get them from?
@swolepoke I wouldn’t add the Art academy cards since they technically got an official release. But it would be interesting to know which cards never got sold.
@genchiro @TheMarillFoundation unfortunately I can’t remember, I saved them years ago in my google Drive with many others artworks and cards that I thought were interesting. They were probably floating around twitter though, since it’s where I was usually for inspiration and tcg contents.
Nevermind lol, found through google lens. They were a proxy unfortunately.
I did know about the Vaporeon but I didn’t know about the Flareon. Wished they were actual cards than in the game only.
Here are some photos online that I’ve saved over the years
The ‘it got away’ lot of e-series Test Prints. All these were under one Yahoo Auction listing
Some more e-series Test Cards
Black border Protostoise
This non-holo holo Clefable from Jungle
Same story with this non-holo Base 2 Charizard
1st edition stamped Unlimited cards
A deck made just for Ishihara. The card inside is also authentic.
There is also a set of 2 Prime cards that are that of Ishihara’s pet dogs but I don’t have that photo. Holo and all
EDIT: Found the photo. WHOOPS, turns out they are non-holo
Man those Japanese prototypes take me back! That was such a once in an lifetime auction!
Oh man! I would have loved it if they made these cards back in the day. I’m surprised there wasn’t a mock up GB Jolteon.
Did an e4 member win that Japanese prototype auction?
I am not sure but I don’t so because none of these cards were ever seen again since. I think it was sold some time between 2015 and 17.
There is a Jolteon. Probably wasn’t mentioned because the artwork was used in Lt. Surge’s Jolteon.
@eeveeteam Nice to see. But we agree these are proxy cards, right?
@chok What an amazing post. Thank you for bringing so much value to this thread. Pretty cool finds.
