I don't know if this entry has been refused, but i came up with this set:
Scizor@Focus Sash
252 at 252 spe 4 HP
-Swords Dance
-Bullet punch
-Reversal
-X-Scissor/Pursuit
So far, it is working wonders. Weaknesses, at least the most notable, are Weavile, Infernape with priorities, Gyarados and Machamp.
I usually use this scizor as a Lead with the purpose of luring Fire attacks. Depending on the situation, i can set up 1 or 2 Swords dances. In very rare cases 3. A fire attack will bring Scizor to his sash, allowing for a reversal to O-KO everything that doesn't outspeed him or isn't resistant. Bullet Punch is here because it's awesome as always and X-Scissor/Pursuit for Psychic and Dark type coverage. X-Scissor tends to do better if you use this Scizor as a lead, while Pursuit is good to KO some limgering Pokemon.
