My own personal offensive creation, given that nintendo were not too kind to umbreon both stat and movepool wise. The stacked EVs in Sp.Def and HP make it a massive tank, capable of taking huge hits. Yawn first and then protect, thereby allowing the effects of yawn to take place. With the enemy successfully incapacitated, nightmare 1/4 of their hp away each turn. On top of this, you could opt for hyper beam, dealing further punishment, OR moonlight to replinish heath. This is crucial if you intend on sweeping a vast majority of the opposing teams pokes.
Enjoy,
