timber just use sludge wave on the field.. it stops pokemon from healing.. and ruins clefable.. would suggest toxicroak.. and if your really all that stuck can always try and get lucario..
At the rate I'm going, that might be my only option. I don't know when my Jolteon will hit 180 since it's already 48 and it might not make it within the level cap... maybe I'll try Escavilier since I need a decent Steel-type, anyway.
