I just finished beating the elite four without trouble. I used Feraligatr, Meganium, Typhlosion, Ampharos(great Pokemon for the elite), Lugia(also amaing for this) and alakazam
You should use either Groudon or your Starter Pokemon. I used a crobat and a garados.
i used dialga,palkia,typloshin,lvl.10machop,giratina,and a staraptor
The members of the elite four are Aron, Bertha, Flint, and Lucian. Aron used bug types, Bertha uses ground types, Flint uses fire types, and Lucian is the psychic type user. You also have to fight Cynthia the champion after u fight the elite four.
Train your Pokémon, and think about type advantages. I don't think I've ever used Kyogre to beat the Elite Four :) Just bring strong pokémon and full restores
An aggron probably... I used an aggron to beat the elite 4...
The Elite Black Armor is rare, you are going to have to buy it from a player (it used to be sold, but they discontinued it)
I used bisharp against the ghost and psychic elete four members, and my electross and serperior against the dark and fighting one.
Gible is not available in this Pokemon version in the wild. to acquire Gible, you must beat the Elite Four and transfer this Pokemon through the Poke Transfer Lab located on Route 15. You must have Gible in your PC in another Pokemon game used on a DS (Diamond, Pearl, Platinum, Heartgold or Soulsilver.) This is true for all Pokemon you want/need in previous generations.
stop depending on an ar and just beat the elite four and carry on from there
You bring different types of Pokemon. The way i beat the Elite Four is: the first trainer is a bug lover, so I used flying Pokemon. the second trainer is a ground lover so i used a water type. the third is a dude who loves fire so use a water type Pokemon. the last is a psy. user i used electric, flying, and water. the champ I used a flying type, she has different types of Pokemon so u can use whatever comes naturally. My Pokemon were 60 and above so it was kind of easy for me. Make sure you get a lot of revives and potions.
