I've lead with Persian before, to Great success.
Persian@ Choice Band/Flame Orb
Technician/ Limber
Jolly- 252 Speed/ 252 attack/ 4 HP
--------------------------------
U-Turn
Fake out
Switcheroo
Bite/ Nightslash
If you are faster than opponent, Switcheroo. Choice Band Switcheroo hurts Swampert who tries Stealthrocking, and owns Bronzong. If opponent is faster, Fake Out and run, respectively saving Switcheroo for later. Once you have Switcheroo'd, Fake out then U-turn for wracking up damage. Works Similar to Ambipom except he runs sans Switcheroo.
Bite if you're running Technician, Nightslash if you're running Limber.
If you ever face a Gengar, run.
Basically, this set is wonderful vs. Ninjask leads/ Set- up leads who think they can Stat-up in your face. With Switcheroo, they'll be locked on. Flame Orb hurts physical leads that Persian outspeeds. This set can be Compared to Ambipom's, but he doesnt have Persian's speed or Switcheroo. He does have a higher attack stat, however.
