This is my first peer-edit, so apologies for anything inappropriate. I've tried out this Drapion set, designed for OU and so far it has functioned well.

<p>Drapion's base Special Defense is substantially lower than its Defense but Drapion's typing affords its useful resistances to Dark, Ghost and Grass-type attacks as well as immunity to Psychic-type attacks and thus allows it to counter a number of Special-based threats.</p>
<p>With these EVs, Drapion's HP and Special Defense reach 344 and 271 respectively. This means that a Timid Gengar can only 4HKO at best with Focus Blast, should it deal average damage. Watch out for Life Orb variants though, which 3HKO with Focus Blast, although there is only a 34% chance that Focus Blast will successfully hit 3 times in a row. With just 12 EVs invested into Attack, Gengar is OHKOed by Drapion with the average damage dealt by Crunch.</p>
<p>Azelf and Deoxys-S are two threats that Drapion can also take on, thanks to immunity to their STAB attacks, with Azelf only able to deal a maximum of 77% damage after a Nasty Plot from a Life Orbed Flamethrower and Deoxys-S only mustering a maximum of 33% damage with Life Orb from Ice Beam or Thunderbolt. Moreover, Deoxys-S' Superpower is a 5HKO with average damage thanks to the continual Attack drops.</p>
<p>Crunch provides a reliable STAB attack, and hits the aforementioned Pokemon for Super Effective damage and is supplemented by Earthquake to provide good coverage in tandem as well as turning Drapion into a good counter for the Boah variants of Tyranitar and also Calm Mind Jirachi. Furthermore, Earthquake is a deterrent for the likes of Heatran and Lucario. Toxic Spikes and Whirlwind are two options that could replace Earthquake. In the case of the former, with Drapion's multiple resistances, it is relatively easy to find time to set up layers of Toxic Spikes whereas Whirlwind enables Drapion to phaze out bulkier threats and scout the opponent's team.</p>
<p>Rest and Sleep Talk provide Drapion with the durability to repeatedly counter the threats for which he is tailored to do so and is also helpful for soaking Sleep-inducing attacks from Pokemon in both OU and UU that carry these attacks regularly such as Gengar, Roserade, Hypno and Vileplume, all of which are Pokemon that Drapion can wall relatively easily.</p>
