Doubles with Torkoal, will include both movesets
Jesus (Arceus) @ Flame Plate
Nature: Modest (+SpA, -Atk)
EV Spread: 252 Spe, 252 SpA, 4 HP
Judgement: Comeon. It's boosted by %130!
ThunderBolt: TB cover water weakness + Bolt-Beam
Ice Beam: BOLT-BEAM! Also covers other 2 weaknesses. Absolute coverage with Bolt-Beam
Calm Mind: Boosting, and Arceus has reasonable bulk to set up
Go in and set up a calm mind, unless the is a major threat, and then spam judgment. The sun pretty much makes water only 1/2 has effective, and 3 target judgment works really well in doubles. Torkoal isn't a huge powerhouse, you can use Judgement effectively.
TURTLE! (Torkoal) @ Heat Rock
Nature: Bold (+Def, -Atk) or Quiet (+SpA -Spe)
EV: 252 SpA, 252 Def, 4 HP
Heat Wave: STAB, Boosted by the sun, Two target
Gyro Ball: Use that speed for something
Solar Beam: coverage, instant in sun
Curse: Boosts amazingly, with the lower speed = more damage on gyro ball!
You can also run this set with just about any drought Pokemon, like P groudon or Ninetales
Hope this helped!
