Ok I've got another one. Didn't expect this guy did ya?
Cobalion@Leftovers
Ability: Justified
Nature: Impish
252 HP/224 Def/32 Spe
~Close Combat
~Hidden Power Ice
~Thunder Wave
~Roar
Cloyster can't touch Cobalion with anything but Razor Shell, and even at +2, Razor Shell is only a 3HKO AT BEST. +2 Razor Shell does 32.52-37.56% which has a mere 8.7% chance of scoring a 3HKO. Meanwhile, Cobalion can cripple with T-Wave, Roar it out, or use HP Ice and then Close Combat for the KO (using Hidden Power first prevents getting hurt more because of the defense drop of Close Combat). No matter how you look at it, Cobalion comes out on top. Not to mention that it quadruple resists Stealth Rock.
