Trainers,

In this special Community Note, we’re excited to share some more details on GO Battle League, upcoming changes to the combat system, attacks that some Pokémon will be able to learn in Pokémon GO for the first time, and some familiar attacks certain Pokémon will be able to learn once again!

Let’s GO!

Leagues, seasons, ranks, rules, and more!

Pokémon GO Battle League will be a triathlon-style contest!

Battles will take place in all three leagues: Great League, Ultra League, and Master League. However, only one league will be available at a time, and they will all rotate throughout a season. This means that in order to be the best, you need to be able to win in all three formats!

However, only one league will be available at a time, and they will all rotate throughout a season. This means that in order to be the best, you need to be able to win in all three formats! As you win battles throughout the season, your rank will increase, even as GO Battle League rotates between leagues. You will start at Rank 1 and work your way up to the top rank, Rank 10. Once you reach a new rank, you cannot drop below it for the rest of the season. Higher ranks mean better rewards!

You will start at Rank 1 and work your way up to the top rank, Rank 10. Once you reach a new rank, you cannot drop below it for the rest of the season. Higher ranks mean better rewards! Once you reach Rank 10, measure against the best with your battle rating. Wins increase your battle rating, while losses will cause it to drop.

Wins increase your battle rating, while losses will cause it to drop. You cannot use two or more of the same species of Pokémon on your team.

As we get closer to the release of GO Battle League in early 2020, you can look forward to more information on how GO Battle League works.

Updates to the combat system

There are some exciting updates coming to the combat system.

When two Pokémon use Charged Attacks at the same time, the Pokémon with the higher Attack stat will go first. If two Pokémon have the same Attack stat, a random Pokémon will go first. We want to ensure Charged Attack ties are broken fairly. Restrictions in Great and Ultra League currently put a focus on trying to get low-Attack Pokémon to maximize CP. While maximizing Defense and HP is a great strategy against most opponents, in close matchups, the Attack stat can now become a deciding factor. We hope this will help deepen team building! Switching Pokémon now clears any changes to its Attack and Defense stats. As more attacks are added to the game that affect Attack and Defense, we want to ensure these effects have clear counterplay opportunities. Debuffs should encourage players to switch Pokémon and buffs should make switching less appealing. There’s more to consider now when to use these attacks and when to switch Pokémon.

Pokémon that can learn old attacks once again

As part of the group of Pokémon to debut with Pokémon GO, some Pokémon originally discovered in Kanto have had their attacks change a lot over time! We’ll be adding back some of the stronger attacks a few of these Pokémon used to learn back in 2016 to make sure these attacks are accessible to players who have joined since then. We’ll look at bringing back more of these attacks over time.

Arcanine: Flamethrower

Poliwrath: Mud Shot

Machamp: Cross Chop

Golem: Ancient Power

Gengar: Shadow Claw
