Wow thanks! That really made it better! However, as you probably noticed, I chose regigigas, one of the most powerful normal types. This is to be immune to ghost (spectral thief) and clear body for topsy turvy (which I have used against MANY of these types of sets. I do believe simple can double efficiency, but clear body really makes it hard to stop.
The issue is to power up before the foe wakes up, Yawn takes 2 turns, and your healing options are limited. Simple allows you to boost Defenses and Speed so even if you don’t Boost Attack you can stay alive longer before Yawn puts it back to sleep. It will power up Power Trip, regardless.
Lol, Raticate-Alola for the anti-Prankster Topsy Turvey, Heart Swap, and Spore, + Spectral Thief Immunity.
Here is another option I use to good success:
Greninja @ Starf Berry
Ability: Harvest
Shiny: Yes
EVs: 252 HP / 252 Atk / 252 Def / 252 SpA / 252 SpD / 252 Spe
Adamant Nature
- Spore
- Belly Drum
- Substitute
- Power Trip
Just add sun support, do a slow u-turn, to Greninja so it can Spore the foe, Substitute on the switch and Belly Drum as the Substitute breaks.
It maxed out Attack so your Starf Berry will boost anything else for +2 the turn you Belly Drum, Harvest activates at the end of the turn to activate Starf again, so by next turn you have +10 stats, or 220 Base power, or 330 after STAB.
It is immune to Prankster, and if backed by Psychic Terrain won’t have to worry about -ates Fake Out or Extreme Speed. Also Harvest activates at the end of each turn, adding even more power.
Heat Rock and Terrain Extender work best on Drought and Psychic Surge Pokemon.
I tend to send out Drought first since Harvest still has a 50% chance to activate if Drought wears off, and because Psychic Surge is more essential for survivability. Maybe 1st: turn U-Turn out the Drought user with a Lagging Tail, second turn U-Turn out the Psychic Surge user with a Lagging Tail, and then 3rd turn: Spore, 4th Turn Subsitute, 5th Turn Belly Drum, 6-9th turn: sweep. (Psychic Surge lasts 8 turns starting from turn 2, hence the sweep from turn 6-9, not turn 8).
You can also always preserve Greninja and reactivate the weather and Terrain so this way when you send Greninja in again. By safely doing so: Harvest activates at the end of the turn, Greninja Spores the foe which allows it to collect Harvest again, Attack the foe as the trainer switches out the sleeping Pokémon (letting Starf Harvest activate a 3rd time in a row), and then by the end of this turn you have +6 to stats making Power Trip 140 or 210 after STAB. Any KOs you get basically allows another Starf Harvest to accumulate, as long as Greninja is alive with the Sun.
