I don't have a flygon. Only have swampert, blaziken, porygon2, gardevoir, magnezone and scrafty.
I could get one but grinding would be time consuming. Just wasted 6 hrs raising my team to acceptable levels only to get curbstomped.
I reached Calcenon already, and battled pretty much all the trainers there. I'm looking for more trainers (wishful thinking) and pokemon that yield high exp.
Oh and my swampert is lvl 66, those battles you mentioned helped level it up from lvl 58.
EDIT: Route 4 it is then...
Just realized that my team is underleveled to face Charlotte (all but one are lvls 61-63), where can I grind my pokes up few levels as quickly as possible?
garchomp - represents the like of pokemon, and one of my favorite pokemon (of many).
