Pokémon TCG: Hidden Fates (Japanese: ハイクラスパック GXウルトラシャイニー High Class Pack GX Ultra Shiny) is a special expansion released during the Sun & Moon Series of the Pokémon Trading Card Game. In Japan, it was released as the twelfth subset of the Sun & Moon Era and the second to be considered as an enhancement of the eighth main expansion, Super-Burst Impact, featuring the collection symbol "SM8b". It primarily contains reprints of Pokémon-GX, appearing as both regular and Shiny Pokémon.
Hidden Fates is a special card expansion first made available in English on August 23, 2019. Its Japanese equivalent, the High Class Pack GX Ultra Shiny is a subset containing 250 cards that was released on November 2, 2018 in Japan, and is considered an enhancement of the eighth main expansion, Super-Burst Impact. It features the collection symbol "SM8b". The core English set consists of cards from the Japanese GX Ultra Shiny, Sky Legend, Family Pokémon Card Game set, Trainer Battle Decks, as well as a number of Japanese SM-P Promotional cards. The English release also includes a second Shiny Vault subset, which consists of cards with Pokémon reprinted as a Shiny Pokémon.
Similar to the Shining Legends and Dragon Majesty expansions, Hidden Fates booster packs could not be purchased separately and instead, were available exclusively in various set-related products.
The Japanese High Class Pack GX Ultra Shiny continues the trend established with preceding subsets The Best of XY and GX Battle Boost—also classified as High Class Packs—by featuring a large amount of reprinted cards, with particular focus on Pokémon-GX. Several of the Pokémon included in the subset feature artwork previously exclusive to promotional cards available outside Japan in various items of merchandise. The subset also includes a large number of Shiny Pokémon, all of which are reprints of cards released during the Sun & Moon Era, have a special embossed Holofoil treatment, and are Secret cards. All regular Shiny Pokémon cards feature different artwork and come in a new "S" rarity, while all Shiny Pokémon-GX utilize their prior Full Art print artwork and come in a new "SSR" rarity. Other than Pokémon-GX and Prism Star cards, all non-secret cards do not have a rarity symbol.
GX Ultra Shiny features 100 secret cards, the most of any set in any language, with 250 cards in total. This makes it both the largest Japanese set and the largest set in any language, surpassing the 236 cards included in the Lost Thunder expansion released on the same day, currently the largest English set. GX Ultra Shiny also has a parallel foil set—each card without a rarity symbol features a Reverse Cracked Ice Holofoil variant. Combined with the standard set, this creates a master set of 375 cards.
To accommodate the large number of cards, each booster pack contains 10 cards instead of the usual 5. Each pack contains 1 guaranteed Pokémon-GX card and 2 Holofoil cards; a parallel foil card may also be included unless it contains a regular Shiny Pokémon. Each booster box contains an average of 2-3 Shiny Pokémon, with 1 guaranteed Shiny Pokémon-GX card.
