Scizor @ Steel Gem
I forgot the exact EVS, but it had some HP, max Attack, and some Special Defense.
Is Pursuit really necessary? I mean, has it done anything worthwhile? In my experiences with Scizor, frail ghosts like Gengar and Froslass are easily sorted by Bullet Punch, and bulkier ghosts like Cofagrigus, Dusknoir and Spiritomb probably aren't going to care much about Pursuit anyway.
Maybe you could use Aerial Ace or Superpower or something? Superpower is nice because it have good coverage, though it's a 4th gen move tutor move which means getting a new Scizor. Aerial Ace is less useful, though it does cover fighting types (Gligar can probably handle many of the fighting types anyway).
Seems like a cool team though. Good luck!
