Elite four pokemon white help?

[Nukez]

Im having troubles with the elite four i have a Haxorus level 53. Emboar level 50 Samurott level 48 Surperior level 46 and colbalion and virizion(those 2 are just switch off just in case for revives) And i beat Grimsley and marshall easy. But omg Caitlin is so difficult none of pokemon in my thing can learn dark moves and my samurott knows X scissor which is 90 power and bug move which is super effective. But it still barely hurts her pokemon. Any tips? This is fraustrating me

I know your pain. For the last 3/4 hours i've been training up different pokemon for each leader. xp share ftw?

You could teach Haxorus X-Scissor, and hope that it will OHKO everything with it's gargantuan attack stat. Alternatively, you could use a Reuniclus with
Shadow Ball or a Chandelure.
