Regulation Set I returns to Pokémon Scarlet and Violet Ranked Battles from 5 January 2026

The next ruleset for Pokémon Scarlet and Violet's Ranked Battles has been announced: Regulation Set I will return from 5 January 2026 onwards, with a currently unannounced date for when it will end.

Regulation I was the ninth official ruleset for Pokémon Scarlet and Violet and first ran from 1 May to 31 August 2025. Pokémon eligible for use includes those in the Paldea Pokédex, Kitakami Pokédex, Blueberry Pokédex, and Pokémon that can be transferred through Pokémon HOME. This includes a limit of two Restricted Special Pokémon per team, such as Koraidon or Miraidon. A full list of Restricted Pokémon available in Scarlet and Violet can be found below.

To find details on the most powerful and successful teams from Regulation I, check out Bulbagarden's coverage from the highest-level events of the format: the 2025 Pokémon World Championships, 2025 North America Internationals, 2025 Grand Challenge IV, and Ranked Seasons 31, 32, and 33.

As a reminder, the Video Game Championships (VGC) and all official in-person events are instead currently using the Regulation Set F ruleset until 31 March 2026, a format that bans the use of all Restricted Pokémon.

This is expected to be the final official ruleset for Pokémon Scarlet and Violet's Ranked Battles before the release of Pokémon Champions and reintroduction of Mega Evolution to Ranked Battles and VGC in early 2026.

 

Ive always found it quite funny that they have to make Cosmog and Cosmoem restricted Pokémon since they are Legendary Pokémon... even though they are really useless and nobody will ever use them
