Some silly ideas for this meta
Big Gains (Kommo-o) @ Liechi Berry
Ability: Bulletproof
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Bulldoze / Rock Tomb
- Dragon Dance
- Bulk Up
- Swords Dance
+4 Atk / +1 Def / +1 Spe in one turn. Probably useless. Kommo-o is the only mon that gets SD + Bulk Up + Dragon Dance, but (from what I can tell) it has no fighting or dragon moves to activate them with.
Bulk Up and Dragon Dance is still a nice combo though. Maybe it could work if you replace SD with Drain Punch?
Shiftry @ Focus Sash
Ability: Chlorophyll
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Fake Out
- Knock Off / Bullet Seed / Leaf Blade / Dark Pulse / Energy Ball / Explosion
- Swords Dance / Nasty Plot
- Growth
Gets +4 Atk or SpA from Fake Out in sun. Most chlorophyll users get both Swords Dance and Growth for +4 Atk from a single activation in sun, but Shiftry is the only one that also gets Fake Out. It gets Nasty Plot as well, so it can go physical or special.
Maybe it's possible to run a sun team? Problem is that two of the sun setters, Zard Y and Ninetails, are special so don't want to have to run Flame Charge. Zard Y could conceivably run a physical set with SD, DD, flame charge and filler. Ninetails could go with nasty plot, calm mind, flame charge and something.
One thing that's apparent is that pokemon will be running a lot less coverage moves. It may be worth building your team to take advantage of as many type-based and ability-based immunities as possible to force switches.
