Close Combat is STAB, Poltergeist is STAB, but you could use Spectral Thief for more reliability or for stealing stat boosts. The main course is Shadow Sneak+Endeavor. You get hit hard go down to 1 HP, use Endeavor, and Shadow Sneak, which is FEAR. This set actually sees use on HO teams, believe it or not.
