"Pokelaad - The best a Pokemon can get ;)"
Lorelei is an ice-type Pokemon trainer, Ice-types are weak against Fighting-type and Fire-type Pokemon, but seeing as most of Lorelei's Pokemon are part water, using Fire-types is a bad idea except for against Jynx. But also because all of Lorelei's Pokemon, apart from Jynx, are part water then you can use Grass-type Pokemon as well. Lapras and Jynx are probably her strongest Pokemon. Her Pokemon are as follows:
Dewgong Lvl 54 (usually in this order)
Cloyster Lvl 53
Slowbro Lvl 54
Jynx Lvl 56
Lapras Lvl 56
So Dewgong is first and you want to get him out the way as quickly as possible, so use a strong Electric-type Pokemon such as Jolteon, Pikachu, Raichu or Zapdos. But I would be reluctant to use Zapdos as it is Flying-type as well, so it is extremely weak against Ice-types. But whichever you chose - teach them Thunder as it is an extremely powerful Electric-type move and also has 70% chance of hitting. Otherwise, just Thunderbolt will do.
Then you have Cloyster which can be taken out very easily one again with an Electric-type Pokemon.
Next is the tricky Slowbro, which is part Psychic-type and part Water-type. The only thing that really takes out a Psychic-type, is a Ghost-type. So unless you were planning on taking a Ghost-type anyway I wouldn't bother. So as it is part Water-type, and doesn't have the possibility to learn Ice-type moves then you can use an Electric-type or Grass-type Pokemon.
Now we get to the hardest part which is Jynx and Lapras. Jynx be taken out by a Fire-type Pokemon such as Charizard, Moltres or Rapidash. Your preference, but also Rapidash is solely a Fire-type so it only has 3 weaknesses in Water, Ground and Rock-types. Whereas Charizard and Moltres are also weak against Ice and Electric-types as well. Also Jynx can learn Ice Punch so just be sure to use a strong Fire-type move such as Fire Blast if you use Fire and Flying-type Pokemon.
We now get to Lapras which is a high level and seems to be invincible! Also it is Water and Ice-type, which aren't weak to the same things... So to beat it's Water-type side, you can use Grass or Electric-type. And to beat it's Ice-type side, you can use Fire, Rock or a Fighting-type. It's a bad idea to use a Fire-type or Rock-type Pokemon as well as its other part is Water.
The Pokemon I used to beat Lorelei first time was:
Pikachu Lvl 53 (to beat Dewgong, Cloyster, Slowbro and weaken Lapras)
Venasaur Lvl 49 (to finish off Lapras)
Charizard Lvl 48 (to beat Jynx)

[FireIron4] sorry my keyboard is STILL totally screwed up and i hate having to use this cap lock i miss my shift key anyways yes i am a girl and i say u should use either a grass or electric Pokemon to deafeat Lorelei POKEMON IS AWESOME DUDES all in agreement say ''I''........''I''...yalls turn...yes im a grl im 12
Train your Pokemon really hard try the get at least 10 levels above your opponents Pokemon when battling the elite 4
Edit: You don't need to get your Pokemon ten levels above hers you just need all of your party Pokemon to be at least at level 50 and I suggest you have these: electric type (I like Raichu and zapdos) fire type (moltres, or charizard is good), water type (I like vaporeon or Blastoise), flying type (pidgeot, moltres, articuno, zapdos or charizard) and i would suggest you bring a Pokemon that knows ice type moves just because the dragon guy would be a pain to beat without them. The team I used was Charizard, Articuno, Venusaur, Vaporeon, Nidoking, Raichu. Oh and to beat lorelei use your electric type because she is the ice type one but all her Pokemon (other than jynx) are water type too.
Lorelei of the Elite Four is in 4 island of the rainbow islands. You need to go there to IceFall cave and help Lorelei beat Team Rocket. Then you need to get 2 passwords for the Rocket Warehouse on 5 island. After you beat Team Rocket in the Warehouse, Lorelei will come back to the Elite Four and you can fight them.
