How To Defeat The Elite Four

Once you obtain the National Pokedex, you can challenge the Elite Four and Alder as many times as you want. The Elite Four all have 5 Level 71s, and one Level 73. Alder has 5 Level 75s, and one Level 77. One Elite Four is Shauntal, Ghost-type. Use Ghost or Dark. Her Pokemon are, in this order, Cofagrigus, Jellicent, Froslass, Drifblim, Golurk, and Chandelure. Next is Grimsley, Dark-type. Use Fighting or Bug. His Pokemon are, in this order, Sharpedo, Liepard, Scrafty, Drapion, Krookodile, and Bisharp. Next is Caitlin, Psychic-type. Use Ghost, Dark, or Bug. Her Pokemon are, in this order, Musharna, Sigiliyph, Bronzong, Reuniculus, Gothitelle, and Metagross. Finally comes Marshall, Fighting-type. Use Flying or Psychic. His Pokemon are, in this order, Breloom, Sawk, Throh, Toxicroak, Mienshao, and Conkeldurr. By the way, you can battle them in any order. This is the order I battled them in. Then comes the Champion, Alder. Use Fire on his Accelgor, Escavalier, and Vanniluxe. Use Rock on Druddigon and Volcarona. Use Fighting on Bouffalant. Do that, with Pokemon with levels in the 70s, and you should win.
