Both Pokemon Diamond and Pearl have Team Galactic as the main antagonist team.
A good team for Pokemon diamond or pearl is probably Empoleon, Staraptor, Roserade or, Steelix, Machamp, and Haunter or Gengar.
I don't know because you didn't type in a team
what do you mean after 245 days?
That's a good team
You can't join team rocket in Pokemon diamond. Actually team rocket is not on the game
any high level Pokemon like an inferape with flame wheel
yes
Torterra, Empoleon, Infernape, Garchomp, Luxray, Snorlax
you can start making a good team by raising all your Pokemon not just your starter i hope i hellped
that's a good team, but get rid of froslass and replace with weavile
