Just something I came up with last night. Tested it, and it worked quite well. In OU. After noticing it had above average Attack, 140 base Defense, Yawn, and
fairly decent HP. Managed to set-up SR %80 of the time with Leftovers. Haven't tested Sash
Torkoal
Name: Lead Koal, can also be called "Suck that Azelf!"
~ Stealth Rock
~ Yawn/Rapid Spin
~ Curse/Protect
~ Explosion
Item: Leftovers/Focus Sash
Ability: White Smoke
Nature(s): Impish
Evs:
252/6/200/0/52/0
Torkoal, as I found makes a pretty good lead, it managed to cause some switches into Starmie, meaning a free SR set-up. It can also Yawn+Protect/Explosion to get a free KO, or to scout. Curse can be used to boost its already great 402 max defense. You can also have Rapid Spin to get rid of SR if you're up against Azelf or Deoxys-E. It is reccomended to have Curse+Spin or Yawn+Protect. Although you can make any combination of the 4. Focus Sash to guarentee an OHKO on Starmie. Or Leftovers for recovery.
It should reach 344/207/402/76/185/189 with this set (HP->Atk->Def->Speed->SA->SD).
Damage Calcs:
From SR Azelf's Explosion:
256-301 damage.
Same Azelf as above, after 1 Curse:
172-202 damage.
