As of this point im actually just posting parts of my rain dance teams, but really i dont mind.
Qwilfish - Adamant/Jolly (i use adamant)
Focus Sash/ Rain Stone (i use sash)
252 Atk, 252 Spe, 6 HP
Waterfall
Rain Dance
Toxic Spikes
Explosion
Non smogon set, but ive seen a few ppl use this set up. Set up Rain Dance, and then your next move sorta matters on what they did. If they did not attack and set up something, go for a boosted Waterfall or Toxic Spikes. If they knock you down to the sash, use waterfall if you have some proof of not being sashed, or Explode out of there. Try it out, its a really fun lead!
