The official themed booster pack Extradimensional Crisis is slated to launch on May 29, 2025. It will mark the next expansion for the Pokémon TCG Pocket mobile app, adding a new wave of cards and content. Extradimensional Crisis has been announced as the seventh full expansion for Pokémon TCG Pocket, and it will release globally in-app on May 29, 2025, introducing over 100 new cards of varying rarity.
This expansion is labeled “A3a” and follows the previous set, Celestial Guardians (released in April), as a supplemental themed booster pack. Serebii.net also reported that Extradimensional Crisis will release on May 29, 2025, highlighting its focus on Ultra Beasts as a major hook for this update.
Card Details and Themes
Extradimensional Crisis is centered around the arrival of the Ultra Beasts – mysterious creatures from another dimension introduced in Pokémon Sun & Moon. “Ultra Beasts…are enigmatic creatures from another dimension. They arrive through Ultra Wormholes and emit a strange, otherworldly energy.”
In this expansion, players will encounter cards like Buzzwole ex, Blacephalon, Nihilego, and Guzzlord ex, along with other Alola-region Pokémon, such as the debut of Type: Null. In total, Trainers can collect over 100 new cards, including multiple Pokémon ex, new Trainer cards, and the Ultra Beasts themselves (e.g. Buzzwole, Guzzlord, and more).
According to early previews, every Ultra Beast will make an appearance in the new set – from heavy-hitters like Buzzwole ex to an eerie Blacephalon. The expansion also features Alola-themed additions beyond Ultra Beasts, with cards such as Tapu Koko ex and Zeraora representing other Gen VII favorites.
Notably, Ultra Beasts have not appeared in the main TCG since the Sun & Moon era, but Extradimensional Crisis brings them back with the familiar “Ultra Beast” label on each card, allowing certain card effects to specifically target them. This thematic focus on Ultra Space creatures and Alolan Pokémon gives the set a distinct flavor and ties into the dimensional crisis motif of its title.
Rarity and Mechanics
Ultra Necrozma ex marks the debut of the first Dragon-type ex card in Pokémon TCG Pocket, arriving as a special promo during the Ultra Beast Drop Event. As a supplemental mini-set, Extradimensional Crisis will add “over 100 new cards of varying rarity” to the game.
In fact, it’s expected to contain roughly 100–120 cards in total (not counting any Secret Rares) based on previous themed releases like Shining Revelry. Collectors can therefore anticipate a full spread of rarity tiers, from common cards up to powerful ex and secret rare cards in this expansion.
Ultra Necrozma ex stands out as a highlight – it makes its debut here as the first Dragon-type ex card in Pokémon TCG Pocket, arriving via a limited-time event (ensuring this shiny legendary will be a coveted pull for players).
Mechanics-wise, Ultra Beasts will act as their own archetype in this set, complete with dedicated Supporter cards and abilities that maximize their otherworldly powers. For example, Celesteela’s “Ultra Thrusters” Ability lets you swap your Active Ultra Beast with one on your Bench once per turn, and the new Lusamine Supporter card allows you to attach two Energy from your discard pile to an Ultra Beast of your choice.
This synergy means Ultra Beast decks can cycle and power up quickly using their unique support. For added flavor, fans have observed that each Ultra Beast’s attack name is a nod to a different music genre (e.g. Buzzwole’s attack “Power Punk”), a fun Easter egg that reflects the “out-of-this-world” theme of the set.
Leaks and Early Info
Extradimensional Crisis was first revealed on May 22, 2025, via an official trailer, which teased an Ultra Wormhole opening and the Ultra Beasts’ imminent invasion of the Pocket app. Fan sites like PokéBeach and Serebii immediately reported on the announcement, confirming the expansion’s title, release date, and Ultra Beast theme based on The Pokémon Company’s press release.
IGN’s social media post likewise highlighted the new set, noting that it “launches on May 29, and features the wacky-looking Ultra Beasts”x.com, which generated excitement among players awaiting fresh content.
