Magnezone @ Leftovers
Ability: Magnet Pull
EVs: 172 HP / 252 SpA / 84 Spe
Modest Nature
IVs: 0 Atk
- Substitute
- Calm Mind
- Flash Cannon
- Thunderbolt/Discharge
A similar set exists in OU utilizing Charge Beam, but Calm Mind is better overall. This Magnezone is good at trapping passive Steel types like Skarmory and Ferrothorn and turning them into setup fodder. Calm Mind is better than Charge Beam because it allows you to setup to +6 against the opposing Steel type without knocking them out, and it also makes you harder to revenge kill, while also having more general utility against weaker Pokemon. You can even 2HKO Chansey at +6. And if you're really crazy, you can run HP Grass so no Quagsire can stand in your path.
Azumarill @ Lum Berry
Ability: Huge Power
EVs: 92 HP / 252 Atk / 164 Spe
Adamant Nature
- Play Rough
- Aqua Jet
- Knock Off/Superpower
- Swords Dance
Swords Dance Azumarill is pretty similar to the Belly Drum set, but with a lot less risk associated. One of the main advantages is that it frees up your moveslot as you don't need to run Sitrus Berry, letting you use a Lum Berry to set up easier against status users, or a damage boosting item like Life Orb or Splash Plate. I think Swords Dance users with priority could be good in this metagame, as they can wallbreak through bulkier teams and pick off the faster Dragon Dance users.
Bibarel @ Life Orb
Ability: Simple
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Dragon Dance
- Waterfall
- Return
- Superpower
Bibarel is pretty pathetic on its own, but now it has a decent move to abuse Simple with, which is no joke. After a Dragon Dance, its stats reach levels comparable to that of powerhouses like Garchomp or Terrakion after a Dragon Dance. Water/Normal is pretty good neutral coverage, and Superpower gives you a move to hit Ferrothorn. The main issues with using something like Bibarel are that it's absolutely worthless if it can't set up, it has pretty bad bulk compared to other Dragon Dancers, and it also faces competition from other Water and Normal types, mainly Gyarados and Mega Lopunny. It's definitely a bit gimmicky, but worth mentioning. Bibarel can also use a Swords Dance Quick Attack set, but it seems a bit outclassed, as SD Dragonite, SD Entei, and even SD Linoone outdamage it with Extreme Speed after a boost.
