Just evasion and OHKO moves (Sheer Cold etc) are banned.
Anyways onto the set, dont be so stubborn to smogon sets, that is mistake #1. Remember, being original for the sake of being original makes you lose and with such a one dimensional pokemon like Pinsir going with the standard is better.
Mold Breaker as the ability - its biggest selling point is to beat its counters such as Weezing and Rotom by negating their ability.
Ether way Seismic Toss is pointless, set 100 damage on something with such high attack ? No, use Earthquake over it. Seismic Toss is better left to pokemon who cant attack well, e.g Blissey.
Stone Edge >> Vital throw so you don't get completely shut down by anything flying and has amazing coverage with Stone Edge and X-Scissor and use Swords Dance Focus Energy sucks. Vital Throw also sucks, it makes you go last and that is counter productive. :/
Dont use Noctowl offensively (i.e "it really doesn't need a hidden power"), its so overshadowed by things like Xatu, even Chatot when used like that.
Night Shade/Whirlwind/Roost/Reflect or Toxic with a tankish ev spread bias towards sp.def is the way to go.
