@Ineffable: Thank you for your post, he does have nice looking defense all around. I am probably going to stick to Bronzong, since he resists alot of my glaring weaknesses. But I may try a Dusknoir sometime.
Sometimes in the Battle Factory in Heartgold I use a Dusknoir like this:
@ Leftovers
Curse
Pain Split
Confuse Ray
Attract
I'm not sure what nature it is. I really like it and I don't think it's ever fainted on me.
There's my Dusknoir experience. :P If you're concerned about being able to evolve it early, Dusclops is actually just as good as Dusknoir, only lower Attack.
I know that wasn't a very good description but there you go. xD
