- Encore and Torment used together force an opponent to use struggle or switch.
- Trick, Switcheroo or Bestow whilst holding the Choice Band, Choice Specs or Choice Scarf and Torment used together force an opponent to use struggle or switch.
- Follow Me, Wide Guard, Mat Block or Rage Powder can cause opponents to attack one of your Pokemon whilst the other can safely set-up with Dragon Dance, Shell Smash or Belly Drum etc. or use Focus Punch without being hit.
- Two fast Pokemon that know Belly Drum and Psych Up can set-up in 1 turn [I recommend Linoone and Mega-Medicham]
- Heal Pulse can be used on Pokemon that would make great stallers but have no HP recovery moves, like many physical walls.
- Multiple-opponent moves like Razor Leaf, Rock Slide, Heat Wave, Earthquake, Surf, Discharge, Dazzling Gleam, Explosion etc. can give 2 turns of damage in 1 to two different Pokemon.
[Your allies can dodge these moves with the ability Anticipation or the semi-vulnerable moves like Fly, Phantom Force and Dive etc., Protect themselves with Spiky Shield, King's Shield, Protect or Detect, take no damage because of immunities being Normal, Ground, Flying, Ghost, Dark, Steel or Fairy Type, having the beneficial abilities Sap Sipper, Storm Drain, Flash Fire, Levitate, Lighting Rod, Water Absorb etc. or using moves to get said abilities like Role Play, Skill Swap or Magnet Rise etc.]
- Helping Hand boosts the power of an allies attack.
- Gastro Acid can be used to remove negative abilities of your allies or positive abilities of your opponents.
- Skill Swap can be used to remove the negative ability of your ally and then give it to your opponent as well as giving your ally a more useful ability like sturdy skill swapped by a Carbink.
- Combining Prankster with Taunt and a status-inflicting move like Thunder Wave, Will-O-Wisp, Toxic or Sleep Powderb etc. will mess up many double battle strategies (a LOT of them rely on setting-up) whilst damaging the opponent because of a burn or poison or wasting their turns because of paralysis, sleep or being frozen.
You can generally just set-up quicker like activating a weather condition via Sanstorm, Hail, Sunny Day, Rain Dance, Sand Stream, Snow Warning, Drought or Drizzle or use Toxic whilst your ally uses Venoshock or Hex.
