TTar @ Leftovers
Trait: Sand Stream
Adamant Nature (+Atk, -SAtk)
- Dragon Dance
- Rock Slide
- Earthquake
- Taunt/Thunder Wave
Taunt is really an option, since the AI abuses DT. Taunt will grant you a free setup against pokes like Blissey and Umbreon (in the late games in the frontier, they are somewhat common). TWave is nice for a para support if you really need it.
Celebi doesn't appear ingame, and Cloydol isn't hard to kill (either set up before it appears, and then RS it to its graveyard, or simply send a water type to finish it)
