League Club Coaches

After you have defeated the League, you will be able to invite one of 23 different coaches to the Blueberry Academy in exchange for 200 BP. These coaches are Friends, the Gym Leaders, Elite Four and teachers from Paldea. They will stay in the League Club for a short time before leaving

When they arrive in the League Club, you can talk to them and they will ask you a variety of questions about your role in the Academy and how they can help out when over there to teach. On the first interaction, they will challenge you to a battle. Defeat them to get a reward and this will unlock their first "memory". They will leave either when you invite a new Coach after having 2 or after 6 hours

On their third visit, they will thank you for the talks you have had with them and will offer you a special Trade for one of their Pokémon and each time they come to the League Club, you will be able to battle them again even if you have already done so today.

Each character has got two memories to unlock in total and completing these memories gives you access to their trades. The more trades you do, the more access you get to other coaches, though some have got additional requirements to unlock them as well. These trades include other coaches as well as the Blueberry Elite Four members that appear in the club

The Blueberry Elite Four also appear in the League Club and act in a similar manner, with trades, and rewards for battling them. They will change up every day.
