I was looking at Butterfree for my team, but I actually prefer to use my non-types for my leads with gyms.
I came up with Drapion and I actually bred one with pretty good IV's.
25HP/31Atk/30Def/31Def. So I think it fits the spot pretty nicely.
There's no way to explain it fully in a few words, but basically a sort of ladder system set up like a martial arts dojo where people can battle to earns higher ranks, and only fighting type POkmon are allowed.
Well it couldn't kill a heracross that had a CC defense drop in one hit, and I retaliated with a Guts Night Slash for a 1HKO, so I don't mind it circulating. XD.
