Ok I know we aren't supposed to answer old questions but I HAVE to answer this one.
Salamence
Jolly and Fire Blast? Really?
Maybe try a Naive nature and Fire Blast or keep your nature and
get Fire Fang (Move Remember). Otherwise looks pretty good.
Rotom-W
Nice set. I liek it. Pretty sad though that this thing gets no other
Water-type moves (apart from HP water which is quite weak).
Ferrothorn
Power Whip can miss at crucial times so try Seed Bomb
(this might be really hard as you have to breed again). Also
this thing is really weak to Fire so use the berry that reduces
super-effective damage and you should be good.
Excadrill
Good set. Also gets rid of those nasty unwanted hazards that are a nuisance.
Over all good set but the EVs can be changed. Try 32 Speed to
have some hope in outspeeding Rotom's
that (mostly) run 16 EVs in speed and will cripple you with Will-O-Wisp.
Gengar
The mega of the team! Try a Modest nature because 130 base Speed is fast
enough already. Otherwise really good and can sweep if your
opponents let their guard down.
Aegislash
The final Pokemon. Everyone always runs the same set.
What are the EVs anyways? And there isn't a guarantee
that whatever move the opponent uses will be super-effective
or won't take you out in one hit so why not Swords Dance?
