All 364 cards are listed, and none are reconstructed from a list of names. The set order, numbers, types, HP, stage, retreat cost, attacks and rarities come from TCGdex's Japanese records for E2–E5. The card counts match the printed sets exactly — 92 / 90 / 91 / 91 — including the three secrets in each of the last three.
Japanese card names needed rebuilding, and one class of them could not be. TCGdex's Japanese names for this era are machine translations and often wrong: ウィークカバー comes back as 脱力感ガード, サイキッカー as 先見者, 超エネルギーリムーブ as スーパーエネルギー除去2, ナゾノクサ as 奇妙な, ビードル as 雑草. Pokémon names are rebuilt from the species table (all 251 of Generation I and II) using the Pokédex number on each card. Trainer and Energy cards carry no Japanese name here at all — only the English one — because there is no Japanese card face in our sources to check them against, and three of the eighteen we could check were wrong.
The pictures are not all Japanese. The Town on No Map is scanned from Japanese cards (Pokellector's EC1 set, 92 of 92). Wind from the Sea, Split Earth and Mysterious Mountains use English scans of the same illustrations — TCGdex holds no Japanese scans for those three sets. The pairing was made by Pokédex number, then by HP, attack count, damage and retreat cost inside each Pokédex group, and it was verified against The Town on No Map, the one set where both scans exist: of 70 pairs checked by perceptual hash, 66 were the same illustration. The four that were not are all cases where two Japanese cards of one Pokémon share a single English scan. Every borrowed picture is labelled English scan under the card.
Nine secret cards, and they are counted as secrets. Nidoking, Kingdra and Lugia in e-Card 3; Golem, Kabutops and Ho-oh in e-Card 4; Charizard, Crobat and Celebi in e-Card 5. They are numbered 088–090 and 089–091 in their sets and sit at the end of each list. The official printed counts are 87 / 88 / 88; the totals of 90 / 91 / 91 include them.
Two data errors were corrected rather than carried. Buried Fossil at Split Earth 070 is filed by the source as a Pokémon with 30 HP and a Basic stage; it is a Trainer whose effect searches the deck for Omanyte or Kabuto, and it is listed as one. Swinub and Piloswine really do appear twice in Mysterious Mountains, at 032/033 and 057/058 — that is the set, not a duplication.
Holofoil counts are per set, sixteen each. The four sets print 64 holofoil rares between them, plus the nine secrets. No card here is counted twice for having a holo and a non-holo printing; the Japanese e-Card sets did not do that — the separate H-numbered holo run is an English invention, added in Aquapolis.
What is missing, and why it stays missing. Japan's 2002 promotional line is not itemised (see the section above). No card face is invented, borrowed from a different card, or upscaled from a thumbnail anywhere on this page.
