Koren
Ubers Mono-Fairy Team:
Xerneas @ Power Herb
Ability: Fairy Aura
Shiny: Yes
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Geomancy
- Moonblast
- Focus Blast
- Thunder
One of the best setup sweepers in the entire game imo. Geomancy is amazing, as it boosts your SpA/SpD/Spe by 2. It is a two-turn move, however, which is why Power Herb is the item. Moonblast is STAB, and after STAB, +2, 252 SpA, and Fairy Aura (ability making fairy moves have 1.33x power), it does SOOOOO much damage to anything that doesn't resist it. Focus Blast hits Steel types that resist Moonblast, as well as Primal Groudon for neutral damage. Thunder hits the Water types hard (especially as they usually rely on/set up rain, making Thunder have 100% accuracy). Water is, of course, common because of Primal-Kyogre.
Other Possible Moves:
- Flash Cannon can be used as coverage (not recommended--just spam Moonblast)
- Psychic/Psyshock can be used as coverage
- Grass Knot can be used as coverage (not recommended)
-
Outrage
- Megahorn can be used to hit MegaMewtwo (thanks to Koren for this). If so, run 4 EVs in attack, and a Naive nature. You don't mind the SpD drop as much as it is doubled with Geomancy anyway.
Walled By:
- Venusaur/Mega Venusaur
- Nidoqueen/Nidoking
These are the only somewhat viable threats to this Xerneas set, as they resist all of its moves. Poison mono is bad in ubers though, so there really isn't a threat from these Pokemon.
- Primal Groudon (especially Iron Head varieties)
SOOOO common now that it is released. You have to pray for Focus Blast to hit.
+2 252 SpA Xerneas Focus Blast vs. 252 HP / 4 SpD Primal Groudon: 286-337 (70.7 - 83.4%) -- guaranteed 2HKO.
252+ Atk Primal Groudon Iron Head vs. 0 HP / 0 Def Xerneas: 256-302 (65.1 - 76.8%) -- guaranteed 2HKO
If Focus Blast misses either time, you will be dead. Iron Head has 100% accuracy.
Arceus-Fairy @ Pixie Plate
Ability: Multitype
Shiny: Yes
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
- Defog
- Earth Power
- Recover
- Judgment
Bulky Defogger. Defog is, obviously, to Defog. Recover is, obviously, to Recover. Judgement hits like a truck. Earth Power is for Fires/Steels that resist Judgement. Also hits Primal Groudon for SE damage. Earth Power is generally preferred.
Other Possible Moves:
- Calm Mind allows it to set up and generally be awesome. Usable over Defog, because this team has nothing weak to rocks (just that Toxic Spikes can hurt)
There aren't really that many other viable options, without taking away something important.
Walled By:
Flying types resistant to Fairy, so Ho-Oh/Char/Mega Char Y/Skarm/Moltres/Crobat/Talonflame.
Clefable @ Leftovers
Ability: Unaware
Shiny: Yes
EVs: 252 HP / 240 Def / 16 SpD
Modest Nature
- Cosmic Power
- Stored Power
- Charge Beam
- Rest
Cancerfable OP. If you get Klefki to set up screens, it allows Cancerfable to setup a couple Cosmic Powers, Rest off the damage, and get to +6. Then, you use Charge Beam a few times to get even MORE boosts, and spam Stored Power to wreck entire teams (just Rest up when you get too low).
Other Possible Moves:
- Moonblast could be used over Charge Beam, but generally extra boosts are worth it.
Walled By:
- Krookodile (and Krokorok/Sandile) because they are immune to both Charge Beam and Stored Power, but Fairy is SE against these Pokemon so they shouldn't be a problem.
There are a few pokemon who resist both moves, but Stored Power will just overpower them eventually (and +6 Def/SpD and even just +1-3 SpA kills most Pokemon even if they resist Psychic).
Azumarill @ Sitrus Berry
Ability: Huge Power
Shiny: Yes
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Belly Drum
- Aqua Jet
- Play Rough
- Knock Off/Superpower
Standard Belly Drum Azumarill. Belly Drum is to get +6 Attack, Sitrus Berry is to get back to 75% health. Aqua Jet wrecks stuff because of STAB/Priority at +6. Play Rough is STAB for Dragons. Knock Off wrecks non-megas that are weak to it/Pokemon that rely on their items. You could also run Superpower to hit Steels/Normals (Chansey/Blissey, anyone?) hard.
Walled By:
Primal-Groudon: Iron Head does >75% damage so you can't Belly Drum (it outspeeds), Aqua Jet does nothing because of Desolate Land, it resists Play Rough, and Knock Off is a non-STAB dark move with only 65 BP.
Other than that, Azumarill has perfect neutral coverage.
Alternate Sets:
If you don't like running Belly Drum you can run a Choice Band set. Item is Choice Band, Ability is Huge Power, EVs/Nature are the same. Moves are the same, except run Superpower over Belly Drum. You could also run Waterfall/Aqua Tail over Aqua Jet for more power, but generally the priority is preferred for revenge killing.
Klefki @ Light Clay/Leftovers
Ability: Prankster
Shiny: Yes
EVs: 252 HP / 4 Def / 252 SpD or 252 HP / 252 Def / 4 SpD
Careful Nature/Impish Nature
- Thunder Wave
- Light Screen
- Reflect
- Foul Play
REALLLLLY helpful, especially to Cancerfable. Screens are screens. Thunder Wave wrecks some Pokemon (not ground types though, which is common now because Primal Groudon OP). Foul Play wrecks physical Pokemon (i.e. Primal Groudon if it doesn't OHKO you). Light Clay is usually preferred to make screens last longer, but Lefties is usable to set screens multiple times throughout the game. You can also run full 252 Def and 4 SpD with Impish Nature to stop more physical attackers (like Primal Groudon).
Other Moves:
Draining Kiss is usable over Foul Play for recovery, but even with STAB, it doesn't hit very hard uninvested.
Walled By:
Not really anything as it is not an attacker, but Pokemon with Defog remove screens, with Taunt obviously taunt it (but Prankster allows it to set up at least one screen, which is better than nothing), physical or special (depending on what EVs you use) fire/ground moves (so again, Primal Groudon's STABs), but you get up a screen first so that helps, by halving the damage. Ground types are also immune to Thunder Wave (as I said earlier).
Mawile @ Mawilite
Ability: Intimidate
Shiny: Yes
EVs: 252 Atk / 4 SpD / 252 Spe or 252 HP / 252 Atk / 4 SpD
Jolly Nature/Adamant Nature
IVs: 0 SpA
- Swords Dance
- Iron Head
- Sucker Punch
- Play Rough
Typical Mega Mawile set (at least for me). Full speed and Jolly Nature doesn't out-speed much, but it does out-speed most Azumarills so you can either Iron Head, or Sucker Punch before they Aqua Jet. Sucker Punch is priority and Iron Head/Play Rough are STABs.
You should really just run this set. You could go 252 HP instead of 252 Speed and use an Adamant Nature (probably a better choice, but I used this one :I).
Walled By:
Not much. It has perfect neutral coverage. Ferrothorn kinda walls it if it doesn't attack, as it resists Play Rough/Iron Head. Primal Groudon OHKOs I think, so you have to Sucker Punch to do anything.
Overall, this is a great team. It got me to the finals (where I couldn't beat a Primal Groudon, cuz I played bad). The biggest threat to this team is, you guessed it, PRIMAL GROUDON (hate that thing so much when I'm not the one using it). There are ways to work around it, however: Screens (by Klefki) priority (by Mawile Mega--Aqua Jet does nothing in Desolate Land) Focus Blast Xerneas outspeeds and hits hard (if Focus Blast hits, that is) and Earth Power Arceus-Fairy. This is the team I've used successfully, and is one of my favourite teams.
Update: I entered it in another tourney and this time I won. Here is a replay from the semis:

You may want to skip to about Turn 75ish after the first 25 turns (its 93 turns long).
