Welcome to the Gym Leader Castle. Here you will battle against the eight Pokémon Gyms, the Elite Four, and your Rival.
Each Gym of the Gym Leader Castle is set up with three apprentice trainers and the Gym Leader. At the start of each Gym, you will choose your team of six Pokémon, from prefabricated teams or from Rental Pokémon. In each round, you and the apprentice trainer each will choose three Pokémon to battle with. Each trainer must be defeated to progress to the next. After beating the Gym Leader, the next Gym will become unlocked.
Not much of a challenge within the Pewter Gym, as long as you have a good team.
This gym is a lot more tricky that the previous three. A larger distribution of types among the trainers can make the choice of team members more difficult. Watch out when facing Cool♀'s Chansey and Parasect; both love to keep your Pokémon asleep.
A great deal of strategy is recommend for this gym. The Judoboy loves to use Focus Energy. When facing the Nerd, the Pokémon that will actually battle should be send out last, as his first two Pokémon will Explode or Selfdestruct.
