Ultra Prism is the name given to the fifth main expansion of the Sun & Moon Series of the Pokémon Trading Card Game. In Japan, it was released as the Ultra Sun · Ultra Moon dual sets that make up the fifth expansion block in the Pokémon Card Game Sun & Moon Era. It is the first expansion to be centered around Pokémon Ultra Sun and Ultra Moon, which was released about one month beforehand. The English expansion was released on February 2, 2018, while the Japanese subsets were released on December 8, 2017.
The expansion introduces and reintroduces several elements to the Trading Card Game. Prism Star cards are a brand new classification of cards and consist of more powerful Basic Pokémon, Trainer cards, and Energy cards that a player can only play one copy of in each deck. Additionally, the Lost Zone returns, with Prism Star cards going to the Lost Zone when discarded. This set also brings Fossil Pokémon into the Sun & Moon Series, having returned to the original mechanic of Evolving Fossil Pokémon from a shared Trainer card (this time known as Unidentified Fossil) which can be played as a Basic Pokémon. The Japanese Ultra Sun and Ultra Moon sets also began two trends which would be followed by the next several main expansions in Japan: basing the cards on a mix of Generation VII and an older generation, and featuring two separate cards for every Basic Pokémon which evolves twice (typically one has greater utility at the cost of lower HP).
Ultra Prism contains 173 cards, including 10 new Pokémon-GX, 6 new Prism Star cards, and several Pokémon native to the Alola and Sinnoh regions. The Japanese equivalent Ultra Sun and Ultra Moon each feature 78 cards (excluding Secret cards), with Ultra Sun featuring Dusk Mane Necrozma and Ultra Moon featuring Dawn Wings Necrozma. The English expansion brought together the release of the two Japanese subsets and the GX Battle Boost subset.
