Mankey see mankey do. Here is a useful set that almost asuredly will get you a KO in LC.
Mankey @ Choice Scarf
116 HP/ 196 Atk/ 196 Spe
Simple set that utilizes his best moves in a speedy killer. CC is STAB and will maim most Pokemon if not KO. U-Turn is for scouting and always great on a Scarfer. Punishment nails ghost types. And Ice Punch is great for KOing things like Starly, Swablu, and Archen which would otherwise be a threat.
