The official Pokémon website has announced the details for the Pokémon Sword and Pokémon Shield Ranked Battles March 2022 Season (Season 28) which runs until 4:59 p.m. PDT on March 31st, 2022.

Pokémon Sword and Pokémon Shield Ranked Battles March 2022 Season (Season 28)

Compete against players from around the world to climb the leaderboards and earn in-game rewards.

A new Ranked Battles season has begun! The Pokémon Sword and Pokémon Shield leaderboards reset at the beginning of each month, making it the perfect time to dive in. The Ranked Battles March 2022 Season (Season 28) will follow the Series 12 regulations, which means you can battle with up to two powerful, usually ineligible Legendary Pokémon at your side. Also, Pokémon are allowed to Dynamax or Gigantamax, increasing the potential drama of each new battle. See below for the full list of eligible Pokémon.

Pokémon Sword and Pokémon Shield Ranked Battles offer the opportunity to test your skills as a Trainer in head-to-head battles with players around the world, move up the global leaderboards, and earn helpful in-game rewards. The Ranked Battles March 2022 Season (Season 28) will run until 4:59 p.m. PDT on March 31, 2022.

Only Pokémon obtained in Pokémon Sword or Pokémon Shield or those with the battle-ready symbol are eligible. Pokémon from previous games in the Pokémon series can receive the battle-ready symbol from the character next to the door in the center of the Battle Tower. When the battle-ready symbol is applied to your Pokémon, your Pokémon will forget the moves it knows. If your Pokémon forgets moves that it cannot use or learn in Pokémon Sword and Pokémon Shield, these moves cannot be relearned.
