The Battle Team page can be accessed by hovering over the "Home" tab. On the Battle Team page, you can make up to 5 battle teams which you will use when Battling with other users.
Creating a Battle Team
In each team, you can only add up to a maximum of 6 Pokemon. They will be the Pokemon you will use when you're battling with another user. When adding a Pokemon to a Battle Slot, it's Sprite, Name, Level, EXP Bar, and item will be displayed. You can also view the Pokemon's stats by clicking the "Show Stat" button.
Note: You cannot add/change/edit your battle team while you're in a battle.
