English New Expansion 'Delta Reign' Prereleases to Begin on the 24th… 40-Card Decks and 4 Prizes
Four Build & Battle Box promos revealed… Official release set for November 6

Prerelease events allowing players to experience the new English Pokémon Trading Card Game expansion 'Mega Evolution—Delta Reign' ahead of its official release will begin on October 24. The Pokémon Company International (TPCi) announced the schedule on its official website on September 28. The official release date is November 6, and the expansion features over 135 cards.
40-Card Deck and 4 Prizes
Starting October 24, select Play! Pokémon stores will sell the 'Delta Reign Build & Battle Box' and host prerelease matches using these boxes. Nearby events can be found using the official 'Event Locator'.
Prerelease formats differ from standard tournaments in deck size.
| Item | Prerelease | Standard | |---|---|---| | Deck Size | 40 cards | 60 cards | | Prizes | 4 prizes | 6 prizes | | Card Pool | Build & Battle Box contents | Entire regulation legal range |
Each Build & Battle Box contains four Delta Reign booster packs, a 40-card ready-to-play deck built with key cards from current and new expansions, and one of four foil promo cards. The promos are Masquerain, Magmortar, Enamorus, and Kommo-o.
Four Revealed Deck Strategies
TPCi also introduced deck strategies for each promo. The Masquerain deck gathers Bug Pokémon that use the 'Bug Out' attack. Spinarak uses the same attack and requires three Colorless Energy, but Masquerain uses the same attack for one Grass Energy and grows stronger with more Bug Out Pokémon in play. It uses the 'Sacred Ash' item to shuffle Bug Pokémon from the discard pile back into the deck for repeated attacks.
Magmortar attaches basic Fire and Lightning Energy to itself or Electivire via its 'Buddy Boost' Ability. Electivire's 'Voltaic Hammer' deals 60 damage for each Energy sent to the discard pile. Enamorus ignores the Colorless Energy required for attacks through its 'Incarnate Solidarity' Ability, which is also shared by Thundurus, Landorus, and Tornadus. According to official descriptions, Landorus deals 110 damage for one Fighting Energy under this state. Kommo-o attaches Energy to Dragon types using its 'Beat Scales' Ability and deals 170 damage with 'Hammer In'.
TPCi stated that players who cannot attend prereleases will still be able to purchase Build & Battle Boxes after the official release.
Domestic 'Release Commemoration Tournaments'
This announcement is based on the English edition and does not include the Korean-edition release schedule. Domestically, Pokémon Korea has historically held 'Release Commemoration Tournaments' at nationwide 'Pokémon Card Shops' whenever a Korean-language expansion is released. The Release Commemoration Tournament for the 'Storm Emerald (스톰에메랄다)' expansion held on August 22–23 required purchasing three booster packs (4,500 won) of the expansion on the day of the event, and was played under the official regulation of a 60-card deck and 6 prizes with a best-of-three, single-elimination format (up to 64 players per session). The format differs from the English prereleases played with 40-card decks.
