another tip if starting new game,
just use your starter,
and ONLY your starter...
by the time you reach the elite four
itll be around levl 84
this is when you dig out your legendaries,
and maybe bring along a few hyper potions,
or revives, just in case they get that
critical hit that they usually get
just as they need one.....
i find that a bad idea, because id just catch pokemon and raise them
