I was thinking of a good way of using simple on numel and found out that it gets great partnership with surskit by receiving an agility baton pass instead of gligar cause of the water weakness.
For a set it may seem gimmick and I haven't tested it yet but how about a simple boosted focus energy? along with scope lens it reaches 50% critical chance which is really good, with it's good base stats it just needs a critical hit to take down most of the LC walls:
Mild (+SpA, -Def)
196 Atk/236 SpA/76 Spe
Hp electric (just for mantyke)
with the 76 spe ev's at +4 reaches 33, which outspeeds kabuto and horsea on the rain.
Critical fire blast takes down gligar, crit quake takes down munchlax, just to name the most prominent walls.
