Pokémon TCG 'Delta Reign' Rules Announced: No Additions to Standard or Expanded Bans

On October 22 (local time), Play! Pokémon, the organized play program of The Pokémon Company International (TPCi), issued a rule change announcement tailored to the new English expansion 'Mega Evolution—Delta Reign.' The conclusion is 'no changes.' Neither the Standard nor the Expanded format has any newly added cards on the banned card list, and the effective date of the announcement is November 20.

Announcement Details: No Changes to the Ban List for Either Format

The announcement lists the announcement date (October 22, 2026) and the effective date (November 20, 2026), summarizing each format in one line. Both Standard and Expanded state that "there are no changes to the banned card list." In the detailed explanation, it noted that banning cards in Standard will be an "extremely rare occurrence" and added that it will continue to analyze tournament results and community feedback to maintain a healthy play environment.

The announcement contains no items other than banned cards. It did not address errata (card text corrections), rule text revisions, regulation mark rotations, or the tournament legality date for Delta Reign cards.

Based on the official banned card list page, the current status is as follows:

| Format | Current Banned Cards | This Announcement | |---|---|---| | Standard | None | No additions | | Expanded | 27 items (including Archeops, Reset Stamp, Shaymin-EX, Scoop Up Net, etc.) | No additions |

Dates for Deck Builders: Released on November 6, Legal from the 20th per Handbook Rules

According to the official product page, the English edition of Delta Reign will be released on November 6 and consists of over 135 cards. It includes over 20 Trainer cards, over 35 special illustration cards, and features Mega Rayquaza ex, Mega Golurk ex, Mega Malamar ex, and Mega Golisopod ex. The product page displays a 'Standard Legal' label. Prereleases will take place starting October 24 at select Play! Pokémon stores using Build & Battle Boxes, utilizing the 40-card deck and 4-prize rule.

The tournament legality date was not included in this announcement. However, the TCG Tournament Handbook (Section 4.1.2), revised on September 1, stipulates that new expansion cards become legal for tournament play on "the second Friday following the U.S. market release date." Applying this rule to the November 6 (Friday) release results in a legality date of November 20 (Friday), which matches the effective date of this announcement.

Looking at the table in the same handbook, the regulation marks currently usable in Standard are H, I, and J. G is restricted to Expanded. This composition was not changed by this announcement.

November 20 is also the opening day of the first International of the 2027 season, the Latin America International Championships (São Paulo, Brazil, November 20–22). According to the handbook's calculation, the TCG division of this tournament will be held with the card pool including Delta Reign without any banned card changes.

For Korean Players

This announcement applies to rules for TPCi's Play! Pokémon tournaments. The announcement did not mention Korean-language editions or Korean official tournament regulations. Neither this announcement nor the official product page confirmed when the expansion corresponding to Delta Reign will be released in the Korean edition. Domestic players heading to overseas Regionals or Internationals only need to keep in mind that the ban list remains unchanged and Delta Reign is added to the card pool for tournaments following November 20.
