5th Gen Who should I choose to go up against the Elite 4 in Black 2?

I am only wanting to use Gen 5 Pokemon.

So far I have came up with bringing Krookodile, Chandelure, and Samurott though I am open to suggestions if I should replace them.

Krookodile
Earthquake
Crunch
Stone Edge
Superpower

Chandelure
Shadow Ball
Fire Blast/Overheat
Energy Ball/Hidden Power Fight/Hidden Power Ice/Psychic

Samurott
Hydro Pump/Waterfall/Aqua Tail/Surf
Ice Beam/Blizzard
Megahorn/X-Scissor/Superpower/Hidden Power Grass/Air Slash

---Some possible choices---

Haxorus, Darmanitan, Excadrill, Terrakion, Virizion, Golurk, Beheeyem Braiviary, Sawk, Zoroark, Mienshao, Druddigon, and Bisharp.

Hm, I would suggest Golurk if you didn't already have Chandelure, just to make it more interesting.

But of the others you have, i'd take Beheeyem, Sawk and Druddigon, though I just say that because I like to see teams that don't use as many overpowered things as possible. (No offense to those that do)

Sorry hun, but team advice doesn't go in this section. :c
We have a thread in the Battle Center for it, called the In-Game Team Help, where you can get advice on your team. c:
Or, if you'd like, you can send me a private message and I could help you personally. c:

Good luck!
