It sports excellent 70 / 75 / 65 bulk, (AC) and recovery in Roost and can use Knock Off to support the its team. Vullaby can check Fighting-types with its STAB Flying-type attacks., (Remove period, AC) or it Vullaby can even run offensive sets to take advantage of its excellent coverage, although Vullaby it must invest heavily in offenses before it can deal respectable damage, typically making it setup bait. Vullaby dislikes any sort of residual damage, which is a problem when it is weak to the Rocks it tries to remove as it is weak to Stealth Rock,.

Defog
########
name: Defog
move 1: Defog
move 2: Roost
move 3: Knock Off
move 4: Brave Bird / U-turn
ability: Overcoat
item: Eviolite
evs: 116 HP / 236 Def / 76 SDef / 36 Spe
nature: Impish
Moves
========
Defog is the main move, and it is allows Vullaby's goal to remove entry hazards, (AC) to alleviateing pressure on your teammates. Roost gives Vullaby recovery and goes fantastically well with Vullaby's excellent bulk. Knock Off can deter setup and support your teammates, although it deals pitiful damage without investment or a super-effective hit. Brave Bird is another STAB option that lets Vullaby deal damage to Fighting-types although the recoil will cut into Vullaby's lifespan longevity (Better word). U-turn can be used over Brave Bird to maintain momentum on VoltTurn teams. Heat Wave can be used to deter Pawniard from switching in on Defog, given that it can 2HKO the Eviolite set Vullaby. Air Slash is an option instead of Brave Bird if you don't like the recoil, but Brave Bird generally hits harder.
Set Details
========
The HP EVs hit a Stealth Rock number to minimize residual damage., (Remove period, AC) while the rest EVs are put into both defenses to hit Eviolite numbers and enhance Vullaby's bulk. The leftover EVs are put in Speed to outspeed uninvested base 53-62 Speed Pokemon, such as Fletchling. A Relaxed nature should be chosen if Vullaby is running Air Slash or Heat Wave, and any EVs in Speed should be moved to Attack or Special Attack. If that is done, the Speed EVs can be moved into Atk or SpA. Eviolite gives enhanced bulk, since Vullaby already has recovery.
Usage Tips
========
The main idea of this set is to use Defog as needed, and check various Pokemon including Croagunk, Foongus, and Drilbur. Avoid using Defog if there is a Pawniard on the opposing team. It This set fits best on balance and stall teams or wherever an offensive presence isn't completely necessary. Overcoat lets Vullaby switch into powder moves, so don't neglect the opportunity switch in and get a free Defog or Knock Off.
Team Options
========
Sturdy users and Pokemon that are weak to Stealth Rock, such as Tirtouga, Onix, Larvesta, and Ponyta appreciate Vullaby's hazard removal. These include Tirtouga, Onix, Larvesta, and Ponyta. Chinchou has near-perfect (Remove hyphen) synergy with Vullaby, resisting Ice- and Electric-type attacks and helping against certain Rock-types. Vullaby can switch in on Ground-types for Chinchou and take out Grass-types and Croagunk. Mienfoo also appreciates the removal of Grass-types and Crogunk and can beat Pawniard and Sturdy users that threaten Vullaby, however the two share a weakness to Fairy-types.
Nasty Plot
########
name: Nasty Plot
move 1: Nasty Plot
move 3: Dark Pulse
move 3: Air Slash
move 4: Hidden Power Fighting / Heat Wave
ability: Weak Armor
item: Eviolite
evs : 116 HP / 240 SAtk / 120 Spe
nature: Modest
Moves
========
Nasty Plot is the main move on this set, use Nasty Plot it when Vullaby's main checks and counters have been weakened and / or (Add spaces) removed. Dark Pulse is the obligatory STAB move and hits Pokemon such as Archen, Chinchou, Misdreavus, and Drilbur. Air Slash is the secondary STAB move and hits Fighting-types and other Pokemon that resist Dark Pulse resists. Dark Pulse and Air Slash have a useful flinch chance as well and can help in a pinch. Hidden Power Fighting and Heat Wave serve the purpose of hitting Pawniard. The choice depends on what other threats need to be covered. Hidden Power Fighting hits bulky Normal-types like Porygon and Lickitung whereas Heat Wave hits Ferroseed harder.
Set Details
========
The EVs maximize Vullaby's Special Attack and give Vullaby 14 Speed, letting it outspeed the entire unboosted metagame after Weak Armor activates. The leftover EVs are thrown into HP to give Vullaby even better bulk. Eviolite is chosen to give Vullaby better bulk to let it set up much easier, even though this set lacks recovery. Weak Armor is chosen so Vullaby can get +1 Speed against physical attackers. This is key to Vullaby's ability to sweep.
Usage Tips
========
This set fits best on bird spam teams and offensive teams in general. Vullaby should be saved for a mid- or to late-game sweep to break down the opposing team or clean up after something else.
Only set up on physical attackers like Timburr, Mienfoo that lacks Taunt, Croagunk, Trubbish, Ponyta, and Pawniard. The big things Vullaby can set up on are Timburr, Mienfoo that lack Taunt, Croagunk, Trubbish, Ponyta, and Pawniard. You can set up on Archen, but offensive sets will win and Vullaby can't switch in directly on any other set. In general, Vullaby's natural bulk will aid it immensely in setting up against offensive threats.
Team Options
========
Flying-types are the top partners for Vullaby since it can set up on and defeat several Flying-type checks. These include Fletchling, Archen, and Doduo. Misdreavus is a good partner, since as (As > since) Vullaby beats Pawniard and can weaken bulky Normal-types, some of Misdreavus's best checks. Pawniard is another helpful teammate that can weaken Spritzee and bulky Normal-types for an easier sweep. Slow pivots like Mienfoo and Chinchou help Vullaby get in to battle safer so it doesn't have to take a hit with -1 Defense while it sets up.
Offensive
########
name: Offensive
move 1: Brave Bird
move 2: Knock Off
move 3: Roost
move 4: Hidden Power Fighting / U-turn
ability: Overcoat
item: Eviolite
evs: 116 HP / 156 Atk / 80 SpA / 120 Spe
nature: Jolly
Moves
========
Brave Bird is a powerful STAB move with great offensive coverage. Knock Off is a very spammable STAB move that can cripple Flying-type checks and other bulky switch-ins. Roost grants Vullaby longevity and can alleviate hazard damage. Hidden Power Fighting is used to lure and beat Pawniard for Fletchling, possibly paving way for a lategame sweep. If Diglett is a teammate, U-turn is preferred over Hidden Power Fighting to allow for easier trapping. (These sentences are a bit short and sharp, I recommend elaborating on each of these)
Set Details
========
The given EVs grant Vullaby enough power and speed to outrun 60 Speed neutral Chinchou and 2HKO the Berry Juice variant with Knock Off. Eviolite is chosen to enhance Vullaby's bulk and is the best option considering Vullaby has Roost. Overcoat is the best ability choice and lets it switch into powder moves, albeit somewhat rare.
Usage Tips
========
This set isn't as bulky as the first set so try to avoid stronger neutral attacks., It is meant for bird spam teams as a means of weakening Fletchling checks, so offensive teams work best. The idea is to just spam Knock Off and Brave Bird and heal with Roost as necessary.
(Add space here)
Team Options
========
This set is designed for bird spam teams, so Fletchling is the number one partner. Diglett can be run alongside Vullaby to beat Pawniard. This set doesn't have defog, so a way of removing entry hazards removers, such as Archen or Drilbur, is are appreciated, especially considering Fletchling is run alongside this. Good examples include Archen and Drilbur.
Other Options
########
Toxic stall is an option given that Vullaby has reliable recovery and excellent bulk. Whirlwind can be used to deter stat boosters from setting up. Taunt is an (an? This doesn't make any sense - I suggest you go over it and reword it) to block hazards and recovery, but Vullaby doesn't usually have room for it or the speed to run it.
Checks & Counters
########
**Rock-types**: Rock-types, Tirtouga and Dwebble in particular, can hit Vullaby super-effectively with the former having access to Stone Edge and the latter having access to Rock Blast and hazards., namely Tirtouga; who can beat it with Stone Edge and Dwebble; who can beat it with Rock Blast and continue to set up hazards. Archen and Bulky Tirtouga can also just switch back in to reset Stealth Rock. (What do you mean by this?)
**Pawniard**: Pawniard can switch in on Vullaby's Defog and activate Defiant, allowing Pawniard to 2HKO Vullaby with Iron Head or hamper it with Knock Off. forcing it to be wary around it. If Pawniard gets in on defog, it can hit it with Knock Off and beat it down with Iron Head.
**Spritzee**: Spritzee and other fairies Fairy-types can take Vullaby's moves with ease, and KO with their STAB attacks.
**Bulky Normal-types**: Munchlax, Porygon, and Lickitung all easily wall the Vullaby's Nasty Plot set. They can paralyze it as well with Thunder Wave or Body Slam, cutting Vullaby's sweep short. However, Vullaby can hit Porygon super effectively with Hidden Power Fighting. Porygon must be wary of Hidden Power Fighting. (Remember, C&C is from the viewpoint of Vullaby)
**Passive-damage**: Passive damage, such as entry hazards, burn, and Toxic really wears down Vullaby. Stealth Rock, Burn, and Toxic are the best examples.
**Electric-types**: Electric-types, namely Chinchou and Magnemite, can switch in and threaten to KO with their STAB attacks and tank it's Vullaby's Flying-type stab. Both must be wary of Knock Off and a boosted Dark Pulse, (AC) however.
**Knock Off**: If Vullaby gets hit by Knock Off, the number of things it can wall drops drastically. Take care not to let Vullaby get hit by Knock Off, This is why it is imperative to be wary of Knock Off, especially if it Vullaby is needed to wall something dangerous.
