Scizor
If you need a good lead, then Scisor is your guy. Double weakness is a big threat. Attack wise Scizor is very good, but in every other stat is very weak for scizor so be careful.
Scizor is the lead choice for many people, because it is very strong and fast when using Bullet Punch. It is great in the OU as well.
Moveset-
Baton Pass
Swords Dance @ Leftovers
Brick Break
X Scissor
This is a very great moveset when you are trying to set up your party. This great for setting up your strong Pokes. Bullet Punch is good, if you want to go first
Bullet Punch
Quick Attack @Choice Band
U Turn
Swords Dance
Another setup wise good moveset. Use swords dance to set up Pokes, like Salamence. Then use U Turn and switch out.
Counters
Scizor's biggest threat are fire types, as they will kill him with one hit. That is why I recommend teaching it Baton Pass, so you can switch it out, and go onto a Water or Ground Type
