Rate my pokemon peal team and plz tell me how to improve it?

5 out of 10. Your Gyarados should learn another move instead of dragon rage. You should teach it earthquake (found in Wayward Cave after beating Canalave Gym), since it covers up the electric and rock weakness. Your Torterra's moves are good but I'm a bit worried about synthesis, since Torterra's speed is fairly low and it already knows mega drain. You should teach it iron tail (found on iron island B2F). The others are awesome but here are some recommended moves: Staraptor-Steel Wing (Route 209), Machamp-Rock Tomb (Ravaged Path), Alakazam-Shadow Ball (Route 210 after obtaining Secret Potion). Haunter is good. It covers all of its weak points. Although you might want to teach it defensive move like protect or skill swap (Veilstone Dept. Store 3L, a girl in a house in Canalave City). Hope that helped! <3
