How we rank these cards
Price ranking: For each card, we use the first available value in this order: TCGplayer market, mid, then low; if none is available, Cardmarket trend, 7-day average, then 30-day average. We convert USD and EUR values to GBP using the latest daily reference exchange rates before comparing them. Price changes compare our own daily GBP snapshots over the last 30 days.
Rarity ranking: We order the checklist by printed rarity label: Special Illustration Rare, Mega Hyper Rare, Hyper Rare, Secret Rare, Illustration Rare, Ultra Rare, Double Rare, Holo Rare, Ace Spec Rare, Shiny Rare, Trainer Gallery, Gallery Rare, Promo, other Rare, Uncommon, then Common. Cards in the same tier are ordered by market price, highest first. Printed rarity does not measure pull odds, print runs or graded population.
Converted values are comparison estimates; check the marketplace listing for its current price, condition, shipping and availability.
