Card text and rulings
The wording on every card, and the rulings for how it actually behaves, come from PkmnCards, TCG Collector, and Bulbapedia.
Two Bulbapedia pages did most of the work: Confused (TCG), because both decks lean on it, and Gengar (Perfect Order 50), for the exact text of Infinite Shadow.
The awkward rules questions were settled by JustinBasil on why damage counters ignore Weakness and every prevent-damage effect, the Pokégym Compendium on retreating, and Bulbapedia on Special Conditions for how Sleep and Confusion actually resolve.
Deck lists and what people are really playing come from Limitless TCG and the Pokémon.com card database. Full set lists, for checking a card exists before planning around it, come from Serebii. And Joseph Writer Anderson's Mega Gengar ex guide worked out how that deck is actually piloted.
Card data
Names, sets, numbers, rarity, types, HP, stage, attacks, weakness, resistance, retreat cost, and card text come from the TCGplayer marketplace search API. The card scans come from the TCGplayer CDN.
Tournament legality
Regulation marks come from pokemontcg.io, one lookup per card rather than one per set. That distinction matters. Prismatic Evolutions prints Flareon 013 with a G mark and Flareon ex 014 with an H, so a set-level table would call rotated cards legal.
The rotation rules behind the yes or no come from the 2026 Standard rotation announcement and Bulbapedia's 2026-27 Standard format page.
Set symbols, set logos, and rarity symbols
pokesymbols.com, covering the rarities, English sets, and Japanese sets.
pokesymbols has no entry for the Halloween bundles, so the Pikachu jack-o'-lantern stamp on the Trick or Trade cards comes from DexTCG instead.
Energy glyphs and the Mega sigil
The energy type symbols beside every cost, and the Mega sigil beside a Mega card, are both zero-licence SVGs from Poképédia.
Poké Ball
The ball at the top of every page is the app icon from HybridShivam/Pokemon.
Sprites
The animated sprites tucked into the headings are the 3D models from pkparaiso.com, by way of tdmalone/pokecss-media.
