What set does Pinsir normally run? I feel like Mold Breaker should be the ability, and you want EQ for Gengar and stuff. Guillotine seems really helpful for Machamp especially. That said, OHKO move Pokes prefer to be bulky, which Pinsir is not. I mean it's not really frail, and can potentially attempt to be bulky with Struggle Bug and Iron Defense.
I'm not sure what else I should run. I guess X-Scissor is a must, but idk the last slot. Rock Slide is always good, and I could use Bulk Up. Since I have a cleric I may even be able to use Rest. Or Substitute to block status and stuff.
EDIT: Nvm. I need Pinsir to set up SR. I suppose that should be the last slot, since I can't very well do away with the other moves.
