You can bring any pokemon,but be careful,if your on a low level,you get beaten up easy.you sould be level 55 or 60,70 that will be ok. Good luck!
Battle the elite 4 with the Pokemon you want to level up in your party (make sure the Pokemon has the exp.share equipped with it) therefore you can level your Pokemon up without putting it in battle Hope I helped.
an level hundred
uh level up ur pokemon!
Well,Level 70-100 Is A Good Level To Beat The Elite 4.
elite 4
50 and over.
3 level 49 magikarps
the elite 4
Rock/Ground Pokemon from level 55 to 59.
Well, tht depends on what level your pokemon are and what pokemon you have. All i have to say is that 1. Make sure your pokemon are above level 55 when they battle the Elite Four AND 2. Dont battle with starter Pokemon
55 is best reccommended with some hell tough Pokemon
If you can get a garchomp from level 85-100 with some potions you can kill all of them
