>>18464364Ah, forgot to include in my post: assault vest azumarill is also a bad idea. The extra special defense is nice, but most special attackers that you would switch azumarill to in the first place are usually frail and killed by a priority aqua jet.
It seems like you are running assault vest for the surprise factor since people would think it's a choice band, but choice band is still superior for the damage output alone.
Also on pinsir, STAB aerilate boosted Return is powerful, but close combat is better for coverage and quick attack gets the job done in most cases anyway. X-Scissor is also a decent choice, but close combat is better. With a swords dance or even two up, quick attack surpasses return.
Also, when using the team builder just make a pinsir, give him the ability moxie and then just make sure it's holding pinsirite. That way you can try to score some easy kills with pinsir before mega evolving to get up free attack boost. Pinsir still packs a whallop on his own and an unboosted quick attack can still finish off pokemon low in hp.
Hope this helps. Rest of it looks good, although mamoswine isn't really the monster this generation like it was for gens 4 and 5, but it is still a great pokemon to use in OU right now as a lead.
