Im not a fan of CB Scizor, mostly because while it does trap and kill a fair bit on that list, it still loses to shit like Starmie and HP Fire Latios / Latias / Celebi / Venusaur etc etc. I really dislike the claim that alexwolf put out "look it beats everything on that list" when it actually doesn't. Sure, perhapes with a Sub up it doesn't fear them, but you won't have a sub up all the time, and I personally wouldn't pass a Sub to Scizor anyway (when its simply going to U-Turn out). Personally, I think Scarf Genesect does a better job (since it outspeeds the bug weak pokemon that Scizor cannot) but whatever.
I might nominate something later, but I would prefer we didn't add a scarfer this early to the process, I would much rather we finalise our core (maybe a secondary sub reciever?), adding 2 more members, before looking at the threats our team needs to cover, so we can pick our revenge killer then.
Just my 2 cents
