Team suggestion.

[water dog]

mienshao is a rape machine, as is leavanny

the following team covers all 17 types with super effective stab moves if it helps give you an idea:

Leavanny
Hydreign
Golurk
Archeos
[any fighting type]
[any spychic type]

if you want some fun ones to throw in just for the sake of having something no one else will be using, consider beartic or ferrothorn or maractus

or beheeyem, cryogonal, etc etc etc

also eelectross is an asshole, he can cover a lot of types nd has no weaknesses
