Any positive or negative comments?

Eviolite Dusclops is better than Dusnoir in UU,espicially with Hydreigon and Cofagrius wandering around UU now in serch of victims...

A special defensive set should work

Dusclops@Eviolite
Nature:Calm
Evs:252HP/4Def/252
-Will-o-Wisp
-Rest
-SleepTalk
-SeismicToss/NightShade

This is a fairly bulky set that can burn physical attackers an counter the special attackers like Hydreigon and Cofagrius as wel as take at least one hit from a Chandelure.
Also replacing StoneEdge or Earthquake on Darmanitan with U-turn may give your team more offensive momentum as it can screw with an opponents prediction.For Scarfty a Lumberry is usually the better choice than a Sash has a natural bulk that can take most attacks and you can always just switch to Dusclops if needed.I little suggest a more offensive Nidoquen set by replacing Dragontail or Roar with EarthPower.
