I would give it an Air balloon, works out better than Muscle Band. Drapion has better tanking power too, so I would reccomend making him a Tank ( 252 HP instead of Speed, use Adamant nature ).
Outrage w/o STAB isn't near as good, use Fire Punch.
This is a mess, first off. Bold nature, not hardy.
Change Hydro Pump to Scald, Aqua ring to recover, Toxic and Hypnosis, to HP Fire and Protect or Substitute. And you should have a better snake.
While non STAB Outrage still is suckish in most occasions, Krook pulls it off.
Keep in mind, you have a Life orb. Meaning if you can't do more than 10% to your opponent, or sometimes around like 20, you're really just screwing yourself, because your taking damage.
Focus Sash perhaps, although hazards will be rough, consider muscle band. Or screw Fake out and sub in a different move. ( Swords Dance perhaps, or maybe a Swords Dance + Sash user )
