All 314 cards of the five Japanese releases are listed, and none of them is reconstructed from a list of names. The counts match the card database that holds the Japanese scans: 81 in February, 40 in April, 81 in July and 56 + 56 in December. The February and July counts include one card printed past the end of its own set — Alph Lithograph at 081/080 — which is why those two sets show 81 cards against a numbered run of 80. Each December pack adds three instead of one: fifty-three numbered cards, two full-art reprints at 054 and 055, and the secret Pikachu at 056, so 56 cards against a numbered run of 53.
The two halves of the year were documented from opposite directions, and the difference is visible on every card. The 202 LEGEND-era cards had to be read off their English twins, because no Japanese database covers that era — HP, type, stage, retreat cost, attacks, ability and illustrator all come from the English print of the same card, paired one card at a time by name first and then by an image fingerprint, with a hard cutoff: a weak match is recorded as no match, never as a guess. The 112 December cards are first-hand. A Japanese listing of each card gives type, HP, retreat cost, illustrator, the attacks with their Japanese text, and the Japanese rules text of every Trainer, so none of that is translated back from English. English is used there for two things only: the official English card name, and the answer to is this the same card or a different one with the same name.
That last question is where the December packs differ from every earlier set on this site, and the answer is recorded card by card. Of the 112, seventy-eight are the same card in English's April 2011 Black & White, four are a different card of the same species in that same set, fourteen are the same card delayed to Emerging Powers in August 2011, and sixteen are another card of the same species in Emerging Powers. The method is deliberately strict: name, rarity tier, HP, number of attacks and the damage of each attack reduced to its digits — 20+ and 20 are the same attack, not two — plus at least one attack name that matches after normalising case and punctuation. Without that last condition, Whimsicott and Beartic both matched the wrong card: their damage lines coincide with an English card whose attacks are entirely different.
Three of the December cards are reconstructed from inside their own pack, and one from English, and it is marked as such. The full-art reprints at 054 and 055 carry only a name and a HP on the Japanese listing, so their attacks are taken from the ordinary version of the same card in the same pack — Tornadus 047 and Reshiram 013 in Black, Thundurus 019 and Zekrom 020 in White — which is what a full-art reprint is. The secret Pikachu is the same card in both packs, and the Japanese listing gives nothing but its HP, so its two attacks (Energize and Thunderbolt) are read off English Black & White 115/114, the card it becomes four months later. Nothing is invented to fill a gap; where nothing exists, the field stays empty.
The English side of 2010 does not follow the Japanese side's order, and this page does not pretend it does. February's set is split between Unleashed and Undaunted; July's is split between Undaunted and Triumphant, with two LEGEND pairs pulled forward into Undaunted so that they reached English one month after Japan rather than six. April's forty cards are the strangest case: twenty-eight were folded into Unleashed and Triumphant, and the other twelve were held back until Call of Legends on 9 February 2011 — Tangela, Tangrowth, Relicanth, Pachirisu, Mime Jr., Mr. Mime, Seviper, Snorlax, Zangoose, Research Record, Lost Remover and Lost World. Every one of the forty has an English printing somewhere; none of them has an English printing in a set called Lost Link.
One card has no English printing at all: Dodrio (057). February's set carries two Dodrio and English printed only one of them — Undaunted 011, which is 039/080. The other 80 cards all reach English, the two Special Energy cards included: they print as Darkness Energy and Metal Energy at Undaunted 079 and 080, and the only reason 080 needed a hand entry is that the source database labels both Japanese cards Darkness Energy. Dodrio 057's attack names are a plain translation, not an official one, because no official English text exists for that card.
Two data errors in the source were found by cropping the card faces, and both are corrected here rather than carried over. The database labels both of February's Special Energy cards as Darkness Energy — 079 is the Special Darkness Energy and 080 is the Special Metal Energy, which is what the card face says. And July's 025 is catalogued as Venonat when the card is ビリリダマ (Voltorb); the Pokédex number on the card, No.100, settles it. The scan is the authority in both cases, not the field. The December packs needed the same treatment in five places: every Japanese rarity was read off the card face rather than the listing (C, U, R, SR, UR — this era has no RR), two cards that genuinely pay no retreat cost were checked rather than assumed, four HP values were re-read, and one attack name in White Collection is Steel Feelers, not the database's spelling. Those letters are kept as they print. The archive does not translate this set's R into its own Holo Rare category, even though an R card is holofoil, because the card carries a letter and nothing else; that is also why the December packs add nothing to the holo figure in the header, which counts cards filed under the archive's older rarity names.
About the scans. All 314 card faces are full-size scans, each one shown here scaled down from that original, never enlarged from a smaller copy. Two of them are the exception worth naming: the Alph Lithograph in February and the one in July exist on the source only at 253×359, smaller than the 300-pixel floor this archive uses everywhere else, so they are the largest copies that exist rather than the size the rest of the page is held to. The artwork is identical to the card face either way; only the resolution is short. The December packs are all full size — the two secret Pikachus included, at 556×790.
