So I've been messing around with Mono-type battling the last few days (I really enjoy the diversity of move sets I've seen and the ingenuity people have trying to overcome their weaknesses even in the worst match-ups). I built a few teams and about a week ago I came up with a Fairy-type mono team that was built to combat Poison- and Steel-type mono teams (while still covering against almost all other types). I haven't laddered (mostly because I have an aversion to even trying) but the record against counter types is positive and I haven't lost a good match-up yet (my only loss so far was to a well-built Rock-type team that managed to set up Omastar and stall out with Cradily). Here's what we've got!
Cosmo (Azumarill) (M) @ Choice Band
Ability: Huge Power
EVs: 248 HP / 252 Atk / 8 SpD
Adamant Nature
- Waterfall
- Knock Off
- Superpower
- Aqua Jet
Azumarill is definitely the premier beater of this team. It manages to get coverage and priority against a plethora of mono-type teams (it's usually the star player against Steel-types as its typing takes their hits with neutral damage, while dealing a lot back with Superpower). It also plays well against Ghost-types spamming Knock Off in the late game and acting as a way to revenge kill Gengar).
Wanda (Gardevoir) (F) @ Gardevoirite
Ability: Trace
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Hyper Voice
- Psyshock
- Focus Blast
- Thunderbolt
Mega Gardevoir is easily one of the best Mega Evolutions in the game, and its attack typing covers very well against most teams. It is capable of (and does) a sweep straight through Dark- and Dragon-type mono teams. It also adds a very necessary Focus Blast to hit Steel-types and Thunderbolt to take care of the ever-powerful Flying-type. Even more necessary is the Psyshock adding a STAB to deal with Poison-types.
Boo-Boo Keys (Klefki) @ Light Clay
Ability: Prankster
EVs: 248 HP / 252 Def / 8 SpD
Bold Nature
- Thunder Wave
- Spikes
- Reflect
- Light Screen
Klefki adds great support to Fairy-type mono teams. Taking Steel-type attacks with neutral damage while providing a full immunity to Poison-types, Klefki also helps a great deal using Thunder Wave to slow down enemy teams for the rest of the team to deal with (Fairies are great, but they lack a solid speed tier, so Klefki is perfect for the mono-types). It also helps a hell of a lot by setting up Screen/Reflect to allow Slurpuff a safe(r) Belly Drum.
Kisses (Togekiss) @ King's Rock
Ability: Serene Grace
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
- Flamethrower
- Air Slash
- Roost
- Thunder Wave
Togekiss also works well as a support(ish) Pokemon for Fairies. Flamethrower allows it to take out the pesky Steel- and Bug-types. A second Thunder Wave user (that also acts as a Flincher) further supports the rest of the team (while it can also sweep by itself against mono Grass teams).
Blossom (Florges) @ Leftovers
Ability: Flower Veil
EVs: 252 HP / 4 SpA / 252 SpD
Calm Nature
- Moonblast
- Aromatherapy
- Wish
- Protect
I needed a Specially Defensive wall that could act as a cleric to my team. I weighed Florges v. Sylveon for awhile but I decided on Florges because it generally takes Special Hits a little better and that's what I needed.
Splat (Slurpuff) @ Sitrus Berry
Ability: Unburden
EVs: 60 HP / 252 Atk / 198 Spe
Adamant Nature
- Wish
- Belly Drum
- Play Rough
- Drain Punch
Finally, I wanted to add a setup sweeper, and there was none better than Slurpuff. Generally speaking, the only problem this set has is physically defensive Poison-types (like Weezing). Otherwise, the Belly Drum setup allows for either an early lead (ie, predicting against a hazard setter) that can take out 1 or 2 Pokemon before being countered (or otherwise forcing a forfeit). It can also come in the mid-game or late game to clean up.
Welp, that's mono-type Fairies. I personally recommend everyone to try out mono-type battling at least once, you'll be amazed by all the cool tech choices you see people running. Leave comments, let me know what you think about this team. Thanks!
