[quote name='Moxio']I think once you take care of Team Galactic on Stark Mountain, the E4 gets a LOT harder.
This is my team as of right now, I'm still trying to decide what to add/remove: Infernape, Electivire, Garchomp, Starmie are my mains. I'm not sure what two more to add. I was thinking a good flying type might be beneficial, but I am at a loss for a sixth. Dark or ghost, maybe?[/quote]If you're going for flying type, Dragonite is a very powerful Dragon/Flying. If you're going for a Ghost type, Gengar is widely considered the best/one of the best Ghost types.
Dratini can be found in the waterfall located in Mt. Coronet.
Gastly can be found in the Lost Tower.
