I am unsure about the other Poke's...since I'm a little lazy to look up movesets. So I'll post a Scizor set that pretty much everyone use.
Scizor @ Life Orb
EV's: 252 Attack, 252 Speed, 6 HP
If you want to run Choice Band, then use this set
Scizor @ Leftovers
EV's: 248 HP, 252 Attack, 8 Speed
Sorry if I wasn't much help...but I wish you good luck!
