Uh... I can't really read the rest of that Scribble, But I can tell you where to Train for The Elite Four!
The best places to Train are in Victory Road And Route 10
For the Elite Four Rematch, I would Say to Fight Cynthia and Morimoto, and Maybe train on some of the Wild Giant Chasm Pokemon.
Also, Now reading that " Scribble " We aren't allowed to " Make " a Team for you, Although if You post your whole team in a different question, with Moves,Pokemon,Natures and Stats/Ev's then we Can Tell you ways to make your team better, Good luck with the Elite Four :D
