@ Leftovers
Nature: Adamant
Trait: Sturdy
EVs: 252 HP/252 Atk/4 Def
- Stealth Rock
- Rock Blast
- Toxic
- Explosion
Here's your lead.
Set up SR, and Toxic if needed, then Rock Blast. If you want, switch, or Explosion. :D
@ Balloon/Wide Lens
Nature: Modest
Trait: Flash Fire
EVs: 4 HP/252 SpAtk/252 Spd
- Fire Blast/Flamethrower
- Shadow Ball
- Energy Ball
- HP Fighting
Modest Nature boost Sp. Attack and lowers Attack, which we don't need for him.
Balloon is equipped to avoid a first Earthquake, Wide Lens for better accuracy.
Fire Blast/Flamethrower and Shadow Ball for STAB, Energy Ball and HP Fighting for strong types coverage. About the Fire-type move, the first has more power but less accuracy, the second viceversa (if you equip Wide Lens, definitively teach Fire Blast).
@ Life Orb
Nature: Adamant
Trait: Sheer Force
EVs: 4 HP/252 Atk/252 Spd
- Tailwind
- Brave Bird
- Superpower
- U-Turn/Rock Slide
Set up Tailwind, then Superpower, and if its Attack and Defense are too lowered (even from opponent), U-Turn. Rock Slide for some coverage, and Brave Bird for STAB.
Sheer Force + Life Orb combo doesn't give recoil damage.
@ White Herb (if you have DM)
Nature: Timid
Trait: Levitate
EVs: 4 HP/252 SpAtk/252 Spd
- Cheer Up
- U-Turn
- Dark Pulse
- Dragon Pulse/Draco Meteor
First, set up 2 or 3 Cheer Up, to boost Sp. Atk.
Then, Dark Pulse.
If you need, use Dragon Pulse, or then try for a Draco Meteor (MUST equip WH), so you can 1HKO 2 Pokès. U-Turn just in case you need to switch, with the Atk boost will do more damage.
