Pokmeon GO's gameplay isn't modeled after the typical RPG-style of most Pokemon games. Each Pokemon has two types of moves: Fast and Charged. However, depending on the type of battle, a Pokemon's moves will function a bit differently. Player's can either battle other Pokemon at the gym/raids, or they can battle another trainer one-on-one. For casual players, there's the Train option to help newcomers with the different battle system.
The leaders of Team Valor/Mystic/Instinct aren't just there to give Appraisals or advice when playing through Pokemon GO. They can also be challenged to a one-on-one battle. Players who find themselves struggling against Team GO Rocket Grunts or other players in PVP can brush up on their skills by Training. Like anything else, by understanding how battling works in Pokemon GO, the easier it'll be to win.

Select any one of the Team Leaders to challenge, and choose a League. There, players will choose a team of three Pokemon — just like a regular PVP or Team GO Rocket battle.
