Mold Breaker for the common Rotom variants, Assault Vest to give it some survivability against modest Chandelure's Overheat/Heat Wave. Moveset has pretty much perfect neutral and mostly SE against the entire format. I'm debating a similar spread with a groundium-z to ohko kartana with EQ. Basically park it next to Togetic and win.

- Follow Me  
Outslows everything that isn't named torkoal, or some unevolved pokemon and uses After You in Trick Room. Otherwise sets up Tailwind for speed control. Basically I can underslow any Muk or Marowak variant and guarantee that mine move first in Trick Room, even outslows p2.

I know I have a reason behind this spread, I just can't remember. It has something to do with Muk's Knock Off if I recall.

Needed something with Taunt, Knock Off for Eviolite users, and a way to ohko azumarills.
