GO Battle League Season 15 (Hidden Gems update)

Trainers, Season 15 of the GO Battle League is upon us and you know the drill (you’ll see why I used the word drill). Will this Season grace us with interesting buffs and nerfs, unlike the last Season? You will find out about that and more as you read along! Meanwhile, you can check out all about the Season of Hidden Gems here

There’s nothing like a fresh start. Each and every season seems to get more and more competitive, whether that may be from trainers adapting to a new meta, more in-person Pokémon Championships, or even the fact that trainers are showcasing more talent and skill each season.
