[Pokemon Trainer]

The new rules for the upcoming Rating Battle (Season 15) have been revealed. The new season will run from March 15, 2016 to mid-May for Pokémon XY (in the X/Y League) and Omega Ruby/Alpha Sapphire (in the ΩR/αS League).

Format: Double Battles (all Pokémon will be set to level 50 for the duration of the battle and all Pokémon require the blue pentagon. You choose 4 Pokémon out of your 6 and you can't have two Pokémon holding the same item)
Pokémon Restrictions: National Pokédex
Pokémon Limits: Players can register a maximum of two Pokémon to the Battle Box from the following list: Mewtwo, Lugia, Ho-Oh, Kyogre, Groudon, Rayquaza, Dialga, Palkia, Giratina, Reshiram, Zekrom, Kyurem, Xerneas, Yveltal, and Zygarde.
Banned Pokémon: Mew, Celebi, Jirachi, Deoxys, Phione, Manaphy, Darkrai, Shaymin, Arceus, Victini, Keldeo, Meloetta, Genesect, Diancie, and Hoopa.

The Rating Battle Season 15 Special format is about to begin, and it will continue to use the same rules and regulations as the new Video Game Championship season. Get extra practice in as you train for tournaments in 2016. As in the Video Game Championship season, all Pokémon require the blue pentagon, meaning you cannot bring them into your game via the Poké Transporter. Also, all Pokémon above Lv. 50 will be leveled down to Lv. 50 for the duration of the battle.

Pokémon Omega Ruby and Pokémon Alpha Sapphire players will continue to battle against players from only those games in the ΩR/αS League. Pokémon X and Pokémon Y players will compete in a separate league against other Pokémon X and Pokémon Y players in the X/Y League.

The complete Rating Battle Season 15 regulations will be posted soon at the Pokémon Global Link. Please check back for details on eligible Pokémon, time limits, and other restrictions.

Keep practicing for the current Video Game Championship season in Rating Battle Season 15, starting March 15, 2016!
