What is an easy way to do the Pokemon league?
Well in my opinion get a well rounded team with grass water
electric fire phyhic and fighting types and teach them moves to
over come their weaknesses ex:Swampert needs ice beam and then
since your pokemon r strong (they better be) you could take
anything thats thrown at you from the elite four itd be a cakewalk
trust me ( which league this is sinnoh right now i would take a
fire pokemon either a infernape or rapidash to take out the bug guy
i forget his name. again infernape or a water type could take out
bertha except for quagsire the most enoying pokemon in the game.
that will take out flint the 3rd elite who's fire. note in d/p he
ends with a steelix thats when the fire comes in handy again. but
in platinum they change it to flareon. lucian phycics pokemon go
down with dark pulse and shadow ball which you find in normal
gameplay. like a mismaguis would come in handy. and again an
infernape or rapidash would beat up his bronzong and gallade but
remember infernape is half fighting type so be careful with lucian.
then finally mismaguis could help with the gastrodon which is
togekiss in platinum. and the weird ghost pokemon that comes out of
stone. if you get a garchomp from wayward cave or a gyrados you
would help against her garchomp, and again infernape would beat up
her lucario. but catch a shinx at the starting of the game it's a
real help when it's luxray you won't have any trouble with her
milotic. hope i helped.)
