Ho-Oh-Lv45
Lapras-Lv40
Raikou-Lv40
Gallade-Lv40(from platinum)
Porygon-Z-Lv40(fromplatinum)i need to train to beat the elite 4 any ideas??? thnx :-\

The best place to train is probably in Victory Road (The cave before the Pokemon League).Your levels aren't too bad. They're not great, but certainly enough to challenge the Pokemon League. Have you considered buying about 20x Hyper Potions and 20x Revives? They'd help you greatly in the Pokemon League.

yeh but i'd like my levels to be 50s and 45s ish and it's hard to train a typhlosion in a cave...

Yes, like Raysie said, the best place is the Victory Road cause it crawl with many med-exp pokemon....But you can always leveling up by re-battle trainer that have you collected their number via PokeGear..although it's such a pain in the buttocks to wait for trainer to call....If you're using an emulator you can always change the time, forward and backward one hour....

Around that levels I used to train in Route 47, west of Cianwood. You need Surf and Waterfall. Enter in the Cliff Edge Gate and follow the stairs to the exit on the south. Then head west until you find a cave entrance. Go in, take the stairs to go down, exit the cave then surf. Go west until you find a waterfall, and climb it. Then follow the river to the north, and you'll see a patch of grass on the right. There you can find lvl ~35 pokémons such as Miltank, that gives a nice amount of exp.

Oh, and I forgot about Ditto! If you don't OHKO it, you get a nice amount of exp and better EVs!

it's ok now i've beaten them with loads of revives thanx enywayz!

hey i've just beaten kanto gyms (all 8 of em) and now i don't know what to do. plz help.

go through the elite 4 again . their stronger now, and plus you need to train for a special character if you dont know who it is.
