This board shares 13 of its 14 days with last week

The week 7 report was built on 27 October from play up to 26 October. This board covers 14 to 27 October, so the window moved by one day. It added 45 teams from two events on 27 October and dropped 40 teams from 13 October. No official event was played in this period. Because the two boards share almost all of their teams, every Pokémon on at least 60 teams changed in usage by less than one percentage point.

Archaludon and Mega Raichu Y swapped places at the edge of S tier. Archaludon has a meta score of 155.0, up from 153.6, and is the eighth and last S tier entry. Mega Raichu Y is ninth at 154.7, down from 154.8. The gap between them is 0.3 points, so this is a close call between two Pokémon with nearly the same numbers, not a large change in how either one is played.

AI Arena gauntlet

The AI Arena gauntlet has been rebuilt from Reg M-C results up to 27 October. Four teams were added, including the Mega Blaziken team that won UmbreNews #37, and five were removed.

Upcoming events

Reg M-C runs until 1 December 2026. The Latin America International Championships are played under Reg M-C in São Paulo from 20 to 22 November. Ranked Battles Season M-7 also uses Reg M-C. This board is built from tournament results only, so a new ranked season does not change it. A new report is published every Wednesday.
