I think DDRMaster suggested using Sableye in another thread and I came up with a hypothetical set:
Sableye @Life Orb
Adamant
HP 252 / ATK 252 / DEF 4
-Taunt
-Fake Out
-Sucker Punch
-Shadow Claw/Will-o-Wisp/Embargo/Recover/Torment/Whatever
He's immune to Fighting (DynamicPunch), Normal (Explosion/Fake Out), and wrecks suicide leads with a +1 priority Taunt. Sableye and Espeon with Magic Mirror are proving to be quite the anti-leads this Gen thanks to their new abilities.
