Looks good, except Salamence. HP poison is useless in gen V, offering coverage only to grass types, which fire blast already covers. Furthermore, moxie is useless with only one physical move. I'd recommend:

Salamence @ Choice Scarf (fixes your lack of a scarfer too)
252 Attack / 252 Speed / 4 HP
Ability : Moxie
Adamant / Naughty nature
-> Earthquake
-> Outrage
-> Fire blast
-> Hydro Pump

Okay, normally spam outrage which gives you +1 Attack with every KO thanks to Moxie. Choice scarf gives +1 Speed, and thanks to the rest of your team there should be no Steel Types left and Salamence OHKOs the game. Pretty much.

Hydro pump for the gallons of rain teams, allowing you to have a third "STAB". Fire blast deals with Ferrothorn.

Earthquake is simply to deal with Heatran, although if they have a massive weakness to earthquake it is also a viable option to spam with Moxie boosts.

^thanks for that! i think i put HP poison on there for fairy coverage, but fairy isnt in gen v, of course XD

also fyi if anyone was wondering i had focus sash on hydregion for dealing with bouncing gyrados, ive encountered bunches thatve basically wrecked me
