Apart from the already mentioned Weavile, you do have Houndoom / Spiritomb.
Psh, Houndoom and Spiritomb aren't even real OU pokemon. Would you ever see anyone using them if they didn't have Wondergaurd? No. And for Weavile, I'll re-phrase:
I'd like to see a good OU Dark pokemon not 4x weak to one of the most abused types in the game. If you say Fighting isn't abused, Heracross, Breloom, and Lucario would like a word with you. Also Focus Blast Gengar.
On that note, if Ghost is destined to win, I want Ghost/Normal.

Yeah.
