@Storm & CK: Honchkrows' defenses are abysmal. Not good at all. His HP is good and his attacking stats are pretty highly above average, but defenses and speed are in the shitter.
You can CB Sucker Punch with him though. It's a bold move, but my Honchkrow is:
Adamant nature @ Choice Band
252 ATK/252 SPE/6 HP
Night Slash (for those anticipating sucker punch)
It worked OK for me. Takes some prediction and cleverness, but if you "outfox" them with NS when they predict a sucker punch, the ego boost is oh so win.
I would consider Murkrow, but you don't need any supporters. He's faster than Honch, but weaker.
Perish trapping Mismagius over Banette.
Remove Spiritomb. You REALLY don't need him. As long as you have ghosts, Absol works fine like CK said, but you also might consider a Drifblim for passing a massive HP sub to one of your sweepers.
It's risky, but a sashed Sharpedo can taunt and hit pretty hard.
A Shedinja can really mess with your friends head with Wonderguard.
Weavile can go in Spiritomb's stead as an effective sweeper.
Can't go into too much detail. Tired...
