Im having troble with the Elite 4 so I have some quetions to people who have beat their poke a#@.
1) What is the best pokemon to beat Lorelie, My fire pokemon dont work because her Pokemon are part watet.
2) When I win will I be able to trade with Ruby, Sapphire, Emrald and Pokemon Collesium.
3) What pokemon did you use to beat the elite 4 or 5 (including rival)
I really need help as the pokemon in the elite 4 on the original games were much weaker.

1) I use Elecric and grass against Loreli; it works pretty well.
2) You will be able to trade with R/S/E right after you obtains the Ruby and Sapphire from the Sevii Islands. You first need to get the national Dex. by talking to prof. Oak after beating the Elite 4 with at least 60 pkmn in your dex. to get the national one. It's not too hard to get either of these.
3) Level up your Pokemon by using the VS Seeker with different trainers. Once you have them leveled up, use the following:

Loreli - Fire, Electric, Grass
Bruno - Ice, Water, maybe psychic
Agatha - Psychic, Ghost, Dark, Fire
Lance - Electric, Ice
Rival - Assorted team; good luck!

1) Maybe you can use a well trained Electric pokémon. Since that is the weakness of water...But take a lot of hyper potions just in case.

2)You can trade between those games. But of course you must have been to the point that the PokéCentres will let you. (i'm not sure that you can trade to the Colloseum though)

3) I'm still busy on raising my team. I started all over and now I'm going to Pewter City. Anyway... I think that you should take enough potions with you and some Revive could help.

Your opponent's pokémon can be at lv. 65. That's why I train so much before I go there. Anyway I took a water type, a fire type and a Electric type with me.

Wow thanx.
I have an electric pokemon (ZAPDOS and RAICHU) but no grass one's. Thank You

Sure you're welcome.
