By training. I recommend the Vs. Seeker.
Well it depends on your team I would get you pokemon all to level 50 if any thing
My team is the following Snorlax Electivire Charizard Dragonite Tyranitar Walrein what Pokemon would you change, im not sure about walrein
Buy an action replay from gamestop or eb games
You cannot it is only for training to improve your skills and get the type of Pokemon you want on your team if you have the Friend area
A psychic Pokemon like gallade would be find but you already have a fighting type infernape so choose Bronzong or another psychic type Pokemon.
Both Pokemon Diamond and Pearl have Team Galactic as the main antagonist team.
Of course go to My Zone and choose Setup My Battle Team on the bottom portion check any boxes near the Pokemon you want in your team remember only 6 Pokemon can be in your team to remove Pokemon on your team currently check the boxes near the Pokemon on your team and then choose Remove Selected then when your done choosing the Pokemon you want on your team click on Add To My Team.
Improve this answer! My Friend Code in Pokemon Black is 3525 1984 7574.My common team would probably be:100 Mewtwo,100 Origin Giratina,Reshiram,Haxorus,Celebi,and Serperior.
it depends what team of Pokemon you have
Up to six pokemon are allowed in a team.
gallade tyranitar and torterra are your best you can improve by normally levelling up until lvl 1000(lvl ex)
A good Pokemon team would consist of different types of Pokemon.
