First Mienshao set lives 1 EQ from scarf jolly landorus (or just from a jolly one), remaining EV's into Sp Def.
First Mienshao set has enough attack to where Knock Off KO's gengar with HP investment.

Second set speaks more for itself. You can give it max attack, but this HP guaranteed a Serp range iirc.

You can mix up things, but I think those 2 sets are the best here. You can take Reckless if you want, but AV kinda wants regenerator.
