No, but it can make a good coverage/support combo if used correctly
Whimsicott @Focus Sash
Ability: Prankster
EVs: 252 SpA / 252 Spe / 4 Def
Timid Nature
- Moonblast
- Energy Ball
- Tailwind/Trick Room
- U-Turn
Lead with whimsicott to set up Tailwind, then U-Turn out to a different Pokemon. If possible, use coverage on low sp. def Pokemon. Use Trick Room if you plan on using lower speed teammates than the ones I suggest.
For defensive synergy use Toxapex:
Toxapex @Black Sludge
Ability: Regenerator
EVs: 252 HP / 156 Def / 100 SpD
Relaxed Nature
- Toxic Spikes
- Baneful Bunker
- Scald
- Recover
Use scald as STAB and to burn, as well as set up Toxic Spikes, poison physical attackers, and stall with Recover and Black Sludge.
As for stealth rocks, toxic spikes should work well, but if you really want stealth rocks, then:
Gigalith @Weakness Policy
Ability: Sturdy
EVs: 244 HP / 252 Atk / 12 SpD
Brave Nature
- Stealth Rock
- Rock Slide
- Explosion
- Heavy Slam/Superpower
or:
Ferrothorn @Leftovers
Ability: Iron Barbs
EVs: 252 HP / 252 Def / 4 SpD
Relaxed Nature
- Spikes
- Stealth Rock
- Body Press/Power Whip
- Gyro Ball
Ferrothorn is by far the better Pokemon, but it struggles with the same types as Whimsicott does, so it's just up to your preference.
As for wallbreakers, these should go a long way:
Dracovish @Choice Band
Ability: Strong Jaw
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Fishous Rend
- Psychic Fangs
- Crunch
- Ice Fang
and:
Kommo-O @Sitrus Berry
Ability: Overcoat/Bulletproof/Soundproof
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Clanging Scales
- Clangorous Soul
- Aura Sphere
- Flash Cannon/Flamethrower
Both share synergy with Whimsicott, Dracovish's Fishous Rend gets boosted by attacking first, and Kommo-O's mediocre 85 base speed also benefits greatly from Tailwind support.
For the last team slot, you can use whatever you want, but I recommend:
Pelipper @Damp Rock
Ability: Drizzle
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
- Scald/Tailwind
- Hurricane
- Ice Beam
- Hydro Pump
Can be used as a second Tailwind user, freeing up Whimsicott of a slot, as well as setting up rain, which can boost Dracovish's power to obscene levels.
