(other post first)
If you use special attack/speed on a moth it should probably hold a Focus Sash, in case something wakes up and one shots it (weather can mess with this of course..). If it runs HP/speed I think it might take resisted attacks better to switch in (more opportunities?), or might survive a weaker hit from something waking up, and it should probably run Black Sludge to get some health back while it dances so that it will have another opportunity to switch back in later on something it resists.. I guess Life Orb could work if you switch Moth in when something faints, sleep powder, dance, pass or get taunted and start attacking with your life orb butterfly danced unresisted Bug Buzz.. Not much would outspeed this bug after a dance or two, which should help it Baton Pass the boosts or help it if it has to sweep on its own. Should be interesting to try out! One thing's for sure: 252 speed.
