go to serebii.com (or .net i forget) but if you go to google and type in serebii you'll see what I'm talking about

I recomend starting with turtwig though, he's the best starter, and it doesn't matter what types you have as long as there is one type that is good against 50% of your pokemon or if 2 or more of ur pokemon are the same type

Elite 4 types are this though

Bug-these pokemon stink and have a ton of weaknesses so it doesn't matter what you have for this guy

Ground-all ground as long as you have a grass or water pokemon you'll be fine

Fire-he only has 2 fire pokemon though-infernape and rapidash

the others are lopunny, steelix, and drifblim

Psychic-if you have anything thats good against psychic you'll be Ok but his bronzong gives people a hard time because of its steel type

and the champion has these pokemon

Garchomp

roserade

lucario

milotic

gastrodon

and spiritomb

okay for the first its bug i recommend using fire types or flying types. the second is ground use water types or grass types. the next is fire use water types.and the fourth is psychic use a dark type pokemon and the champ is a mixture watch out for her garchomp which is her strongest one use ice or dragon pokemon on garchomp there is also here milotic use grass on it she has a spiritomb its not that hard but its still a challenge she has gastrodon use a grass type and thats it for any more pokemon stuff just ask

kk pay attention right here there quite isnt a designated pokemon to make use of any form can win , however i will be able to supply u a tip 1st u will have to cross into the league till all six of ur pokemon are lvl 50, after which u cant have greater than one million with the identical variety or u will lose believe me

just go through it and find out yourself..you should gain more money and experience even when you die in there
