How to build a mono-Fairy team. Why? Because Fairies rule the doubles arena.
Pros: Great coverage, plus they're the cutest little monsters ever witnessed
Cons: They have no Ground moves and little Fire and Fighting moves. One Steel type ends them pretty fast.
TL;DR summaries:
Mainstays:
Xerneas - Banned in everything but Ubers so only use it there.
Azumarill - It's one of the two physical powerhouses the type has, use it or bust.
Mawile - The other physical powerhouse IF you use its Mega form.
Klefki - The only Prankster in VGC, it does its job well anyways
*Togekiss - Amazing special attacker, but only usable outside VGC. Has Aura Sphere and Flamethrower for coverage.
FAIR-ly good: (I'm punny)
Gardevoir - Has a Mega form but you give up Mawile to use it, still good without it. Cannot Pixelate Hyper Voice in VGC.
Slurpuff - If you're not using Togekiss you're probably using the cupcake, as he has Flamethrower.
Florges - Special wall in singles, has an amazing HA in doubles, also has Safeguard, Aromatherapy, and Wish.
Sylveon - If you're not using Florges you're probably using Sylveon, she has Reflect and Light Screen.
Not all that great:
Mr. Mime
Wigglytuff
Clefable
Granbull
Aromatisse
Whimsicott - It has Prankster, but Klefki has better typing.
Dedenne - LOL NO
Carbink - Not enough HP.
Diancie - So far it looks pretty meh but that might change, VGC'll ban it for sure though
Singles Strats:
- Light Clay Sylveon. Enough said.
- Klefki. Also enough said. If allowed, it has SwagPlay. AKA RageQuit.
- Florges is your special wall if you desire.
Doubles Strats:
- Florges can use Symbiosis to pass an item to its partner in doubles after the partner consumes their item. Belly Drum, usable by Slurpuff or Azumarill, can trigger a Sitrus Berry immediately. Therefore you can pass a Choice Band to Azumarill, or for Slurpuff, give him an Absorb Bulb and use Hidden Power Water to trigger it, and pass him Choice Specs. You could even pass them other items, but these are the big ones.
- Slurpuff's Unburden boosts its speed after it consumes its item. This makes Absorb Bulb a powerful tool in doubles, though sadly the only Fairies to get Surf are Azumarill (meaning a wasted slot on its set) and Slurpuff himself. As mentioned, however, Hidden Power Water can trigger it, though if Florges hasn't already passed her item then Symbiosis activates, which cancels out Unburden. I loathe Hidden Power, though. If you're not playing VGC, consider using Togekiss instead of Slurpuff.
- Klefki has Imprison, which allows you to stop the enemy from using moves you hate until Klefki gets taken out. Klefki also gets Protect, Thunder Wave, Toxic, and plenty else I'm forgetting. Pick what you think will be both useful to you and used often by your foes. Oh and I guess Swagger, if that's allowed. In VGC it will be, but everyone will hate you for using it.
