I wish people actually read the question, huh?
You've got a couple of choices: Choice Band and Leftovers.
I'm sure you know what a Choice Band does, but it's gonna require some moveset-changing.
Scizor @ Choice Band
Ability: Technician
Jolly Nature
252 HP / 252 Atk / 4 SpD
-U-Turn
-Superpower
-Bullet Punch
-Knock Off
Revenge killer, or simply hit-and-run tactics.
Lefties kinda makes me want to run a defensive set. Sorry if I'm being offensive, but right now your Scizor set is an odd mix of defense and offense. I'd advise going one way or the other, but not both.
Scizor @ Leftovers
Ability: Technician
Impish Nature
252 HP / 252 Def / 4 Atk
-Defog
-Tailwind
-Knock Off
-U-Turn
This set clears entry hazards (all of them, so watch out if you've got any up), sets up Tailwind, knocks off an item, then gets the heck outta there.
Hope I helped!
