Things hidden in the artwork, cards that were quietly changed before they reached English, and a few numbers that are stranger than they should be.
How to read this page. The card, set, rarity and illustrator under every image were read from the TCGdex API and are checked. What is said to be hidden inside the artwork is collector lore, and no API can check a picture, so those sit behind a button and are written as things people say rather than things we counted.
Six cards with something in the background. Have a look first, then check what you were supposed to find.

Arceus · Holo Rare
Illustrated by Hajime Kusajima
Artwork edited between the Japanese and international releases, or between print runs. Grouped in the source by reason: mature content, religious and political symbols, accidental gestures, violence and gambling.

Gym Challenge · Uncommon
Illustrated by Ken Sugimori
The original Japanese art was scrapped rather than edited, and redrawn as Squirtle catching her tears. The API credits Sugimori on the version that shipped.

Gym Challenge · Uncommon
Illustrated by Sumiyoshi Kizuki
A Buddhist manji in the original read as a swastika to Western audiences, and was replaced with a generic red ninja emblem.

Gym Heroes · Holo Rare
Illustrated by Ken Sugimori
A graveyard of crosses in the background became a flat purple void.

Team Rocket · Common
Illustrated by Kagemaru Himeno
The pupils were redirected forward. At the original angle it read as looking up a bystander’s skirt, which nobody intended.

Neo Genesis · Common
Illustrated by Tomokazu Komiya
A Sentret suckling from a cow-themed milkskin became milk poured from a jar, redrawn by the same artist.

Neo Genesis · Rare
Cropped to hide the casino backdrop. The corpus filed this as card 74, which is a Snubbull.

Neo Genesis · Uncommon
Same treatment, same reason. Filed in the corpus as card 76, which is a Stantler.

Dragons Exalted · Rare
Illustrated by Akira Komayama
The cannon was turned away from the viewer. Filed in the corpus as card 22, which is a Ho-Oh-EX.

Base Set · Common
Illustrated by Mitsuhiro Arita
Red cheeks in the earliest English runs, yellow after. Collectors call them Red Cheeks and Yellow Cheeks, and the red ones only exist as 1st Edition and Shadowless prints.
One well-known design change is deliberately not in this list. Jynx was redesigned across the whole franchise, not just on a card, and the reason is a real-world story about racial caricature rather than a piece of trivia. It deserves proper coverage, which this is not the place for.
Christopher Rush illustrated Black Lotus, the most famous card in Magic: The Gathering. He also illustrated Mewtwo. This is usually told as “exactly one Pokemon card”, which is the kind of detail worth checking: the API returns two, because the promo art was reprinted in Legendary Collection.

And the reprint, which is why "exactly one card" is wrong.
These four came straight out of the Pokemon TCG API, so unlike everything above them they need no hedge at all.
38
rarity values that actually exist
Rare Holo Star, Rare Shiny, Shiny Rare, Rare Shiny GX and Shiny Ultra Rare are five separate values. A reader would reasonably expect one or two.
41
subtypes
ex and EX are two of them, which quietly folds two decades of card design into a casing difference.
1
rarity written in SCREAMING_SNAKE_CASE
MEGA_ATTACK_RARE. The other 37 are Title Case, so that one is a raw enum leaking through the API rather than a display string.
5 of 7
retired mechanics you can still query
Star, Prime, LEGEND, BREAK and TAG TEAM are all real subtypes. Crystal and Delta Species are not, so those two need a different query.
Collectors are taught that light passing through a card is a bad sign. On a PSA label it is the opposite: light getting through is what says the label is real. A forger adding a fake front adds a layer of paper, and that blocks it.
“If you hold an authentic PSA-certified item up to a light at close range, looking from the back of the label to the front or the front of the label to the back, you should be able to see through the label enough to decipher the text on the other side.”

Worth knowing which way round it goes, because somebody who has only learned the card rule will read a genuine slab exactly wrong.
Card databases know what a Pokemon is worth and nothing about what it did. Twelve of sixty-four, picked for range rather than popularity.
| Pokemon | Debut | Episode | Film | Why it matters |
|---|---|---|---|---|
| Pikachu | Generation I | EP039, Pikachu's Goodbye | M20, I Choose You! | The franchise mascot, and the only one with an Alola Cap form. |
| Mewtwo | Generation I | EP063, The Battle of the Badge | M01, Mewtwo Strikes Back | Genetically engineered, and both antagonist and protagonist depending on the film. |
| Charizard | Generation I | EP105, Charizard Chills | M03, Spell of the Unown | Two Mega Evolutions and a Gigantamax form. |
| Lucario | Generation IV | XY030, Mega Revelations! | M08, Lucario and the Mystery of Mew | Carried a film on its own, which few non-legendaries have. |
| Snorlax | Generation I | EP072, Snack Attack | M20, I Choose You! | Blocks a road in the games and does roughly the same job on screen. |
| Eevee | Generation I | EP040, The Battling Eevee Brothers | M21, The Power of Us | One base form, the most branches of any line. |
| Gengar | Generation I | EP023, The Tower of Terror | M20, I Choose You! | The ghost that the first genuinely frightening episode was built around. |
| Gyarados | Generation I | EP012, Here Comes the Squirtle Squad | M02, The Power of One | The red one is a plot device more often than a Pokemon. |
| Jigglypuff | Generation I | EP045, Song of Jigglypuff | M01, Mewtwo Strikes Back | A recurring gag that outlasted most recurring characters. |
| Meowth | Generation I | EP070, Go West Young Meowth | M01, Mewtwo Strikes Back | Taught itself to speak, which is a plot point rather than a quirk. |
| Lapras | Generation I | EP079, The Lost Lapras | M02, The Power of One | Transport, then a herd, then written out. A full arc for a water type. |
| Dragonite | Generation I | EP063, The Battle of the Badge | M02, The Power of One | The courier Dragonite is a different individual from the battling ones. |
