Hey, all. I've always followed this as a resource for strategies but lurking this thread and this datamine has given me a nasty idea.
Indeedee might be better than we think. Psychic Surge Hidden Ability is huge. Pair it with our Darmanitan and you have a nasty combo for Doubles:
Indeedee
Psychic Surge
-Follow Me: to draw initial attack
-Helping Hand: given that it survives and allows Darmanitan-G to Belly Drum and Zen Mode, can boost Darmanitan's first move.
-Healing Wish/Aromatherapy/Encore/literally anything else
-Attack fodder (Hyper Voice?)
Not sure what item to consider for Indeedee. But this basically allows a Zen Mode Darmanitan-G to safely pull off a Belly Drum and go Zen Mode while the Psychic Terrain stops priority targetting moves, and Follow Me draws in anything trying to stop Darmanitan. This means that the usual Fake Out lead is pretty much useless.
Counters to this:
-A slower Pokemon with Terrain-setting ability, like a leading Rillaboom.
-How to counter: make Indeedee as slow and bulky as possible, undercutting the speed of any other terrain setter.
-A Rock Slide faster than Darmatitan and strong enough to OHKO or Flinch it.
-How to counter: Make Darmanitan bulky enough to survive most Rock Slides of it's base Speed or higher. Maybe give it a pinch berry that capitalizes on this, giving back the 50% necessary to start the mayhem. Not sure where to begin on stopping flinching, haven't played competitively since Gen 6.
Anyways, I think Indeedee is good as hell. Literally the perfect teammate for a setup sweeper, blocking priority and drawing in damage.
