Don't see many people wanting to run Umbreon, so I'll bite with how I like to use it.

You can focus more on defense instead of hp if you don't get wish. More hp just helps wish for when you switch out to another.
Otherwise a standard toxi-staller. Wish passing is nice, and synchonize can help cripple opponents who beat you out on toxic or make them think twice before doing it.
I don't personally like mean look, but I see it often enough. It does feel awesome trapping foes and watching them struggle.
