Question: how to defeat the elite four in pokemon emerald?
Answer: Pretty much you use double kick on Absol and Mightyena, thunder on Sharpedo and ice beam on Shiftry and Cacturne. Then, surf of all of Phoebe's Pokémon, as well as on the Glalie. Use thunder on Sealeo and Walrein. Use ice beam on the dragon Pokémon, and surf on the rest.
