Got a couple sets for this beauty.
First off, an offensive set:
Dancing Beauty
Doredia @Life Orb
EVs: 252 Speed, 252 Spatk, 4 Spdef
Nature: Timid/Modest
Ability: Own Tempo (you'll see why below)
~/Giga Drain / Petal Dance
~/Butterfly Dance
~/Teeter Dance / Hidden Power of your choice
~/Sleep Powder
Switch this into soemthing in can force out--The Ground/Water types and Gliscor are a good choice--and Sleep Powder on the switch. Butterfly Dance on the further switch, then proceed to rape everything. Petal Dance is an option because Own Tempo prevents its confusion (someone correct me if I'm wrong), while Giga Drain compliments the +spdef boost. Teeter Dance can be used if someone switches in something you can't touch, like, say, Shanderaa, and that you need to safely switch something into. OR, Hidden Power for coverage.
Clorophyll
Doredia @Light Clay / Big Root / Shed Shell
EVs: 252 Speed, 212 HP, 44 Spatk
Ability: Chlorophyll
Nature: Timid
~/Giga Drain
~/Light Screen / Sleep Powder / Stun Spore
~/Reflect / Sleep Powder / Stun Spore
~/Healing Wish
Doredia doesn't look like a good Chlorophyll sweeper, but she's definitely an awesome supporter. Jumpluff may be faster, but it's also one hell of a lot more fragile. Doredia isn't too bulky either, but she gets the job done.
Switch her in safely somehow. Paralyze/Sleep the opponent or set up some Screens under the sun with your now more than respectable speed, then pseudo-pass it. Healing Wish is also one of the key moves that separates her from the 'Pluffer: She can fully restore an ally AND have them rock the enemy, since they'll probably switch out of Paralysis/Sleepdom, OR make them even bulkier with the Screen.
One last one:
Shanderaa Trap
Doredia @Shed Shell / Lum Berry
EVs: 252 Speed, 176 Spatk, 176 HP
Nature: Timid
Ability: Either
~/Butterfly Dance
~/Healing Wish if not shed shell / Worry Seed if shed shell
~/Giga Drain
~/HP Dark/Ghost
Why is this a Shanderaa trap? Pair it with the following:
Dugtrio @Choice Band
EVs: 252 Atk, 252 Speed, 4 Spdef
Nature: Adamant
Ability: SAND TRAP.
~/Earthquake
~/Sucker Punch
~/Stone Edge
~/Level Field (60 power 100% acc 100% chance of lowering enemy speed by 1 level)
NOTE: If Overheat missing still lowers Spatk, Dig is an option over Earthquake.
Yep. Sand Trap prevents Shanderaa from escaping, giving it a taste of its own medecine. Unless it has HP Ice, Water or Grass, it's probably not gonna hit you hard, especially if it's Choiced and can't switch from the Fire move.
