How about a Milotic that is just a nice wall:
Milotic @ Flame Orb
Ability: Marvel Scale
EV's 252 HP / 80 Def / 176 Sp. Def
Bold Nature
Recover
Aqua Ring/Refresh
Surf
Toxic
Recover is a quick recovery move that doesn't need much explanation. Aqua Ring can fill in for Leftovers in case you might need it. (Or just want to be extra annoying)
Refresh helps if you don't need a defense boost, e.g. If they're on their last Pokemon, or if you are inflicted with Toxic before you can activate Flame Orb, because if you're Badly Poisoned, Milotic isn't as good of a wall if it is Badly Poisoned instead of just burned.
Toxic can get rid of whatever resists Surf like bulky waters (Especially Vaporeon) and Surf can deal some damage if necessary.
