After Luigi's Mansion 3, there'll be a quick turnaround for the Maximus Cup.
A Pokémon Sword and Shield themed cup, complete with theme, will start running at 2 a.m. ET on November 8 until 1:59 a.m. ET on the 12th. As usual, the goal will be to unlock a new theme for the game by earning 100 competition points based on cumulative ranking.
A preview of the theme was sent from the Nintendo Vs Twitter account:
