I revamped all of the sets and removed the Torment Spiker set. Overview + Optional Changes as well. Everything else is the same.
[Overview]
<p>Skarmory is one of the best physical walls in the game. He is able to switch into many physical attackers and stop them from breaking through a team. Coupled with instant recovery and the ability to Spike-stack and phaze, Skarmory can be tough to take out. Although Skarmory has his problems, namely being weak to common special attacks and not having the ability to stand up to boosted physical attacks, he is a highly recommended Pokemon for any team.</p>
[SET]
name: Physically Defensive
move 1: Brave Bird
move 2: Roost
move 3: Spikes / Stealth Rock
move 4: Whirlwind
item: Shed Shell / Leftovers
nature: Impish
evs: 252 HP / 240 Def / 16 Spe
[SET COMMENTS]
<p>This is Skarmory's trademark set, known for providing excellent support and walling an astounding number of physical sweepers, such as Gyarados and Metagross. With Brave Bird, Skarmory can take a decent chunk out of anyone who doesn't resist it, although one can use Drill Peck if the recoil from Brave Bird is unappealing. Roost removes any damage Skarmory may have taken. As a bonus, it also removes Skarmory's Flying-type for the turn so he takes less damage from Rock- and Electric-type attacks. Spikes causes trouble for any grounded Pokemon, as they lose 25% of their health every switch-in with three layers; however, Stealth Rock is an alternative if you don't have another Stealth Rock user on your team. However, keep in mind that there are many Pokemon who can use Stealth Rock, while there aren't as many Spikes users. Whirlwind removes any stat boosts the opponent may have obtained, and forces in another Pokemon to take damage from Spikes and other entry hazards.</p>
<p>In terms of items, both Shed Shell and Leftovers are good options. Shed Shell lets Skarmory switch out of Magnezone, who can otherwise switch in on Skarmory and OHKO with Thunderbolt. Leftovers, on the other hand, helps Skarmory's tanking ability and heals Brave Bird recoil.</p>
[ADDITIONAL COMMENTS]
<p>Skarmory has a severe lack of Special Defense, taking plenty of damage from neutral special attacks and almost never surviving super effective special ones. Therefore, it is advisable to pack Pokemon who can easily take special attacks. Pairing Blissey with Skarmory forms the infamous "SkarmBliss" combo. Blissey can handle any special attack thrown at Skarmory, while Skarmory can come in on physical attacks targeted at Blissey. Pokemon who resist Skarmory's main weaknesses also do well alongside him. Swampert, for example, resists Fire-type attacks and is immune to Electric-type attacks, and can provide Stealth Rock support, allowing Skarmory to use Whirlwind more effectively.</p>
<p>The EVs maximise Skarmory's defensive capabilities so it can more effectively set up Spikes and phaze. 16 Speed EVs will let Skarmory outspeed Adamant Rhyperior, but this can be increased if you wish.</p>
<p>Skarmory benefits from sandstorm, Toxic Spikes, and Stealth Rock in order to shuffle through teams more effectively. A Ghost-type Spinblocker like Rotom-A or Spiritomb is highly recommended on any team using Skarmory to prevent the opposing team from removing your entry hazards with Rapid Spin.</p>
[SET]
name: Specially Defensive
move 1: Brave Bird
move 2: Roost
move 3: Spikes
move 4: Whirlwind
item: Shed Shell / Leftovers
nature: Careful / Impish
evs: 252 HP / 240 SpD / 16 Spe
[SET COMMENTS]
<p>Giving Skarmory Special Defense EVs may seem odd considering Skarmory's low Special Defense. However, this allows Skarmory to take full advantage of his resistances to Dragon-, Ghost-, and Grass-type attacks and his neutrality to most other special attacks to wall any special attacker who can't hit Skarmory for super effective damage. Just to get an idea of Skarmory's special bulk, Rotom-A and Magnezone, assuming they do not have a boosting nature or a boosting item, cannot guarantee a OHKO on Skarmory. Timid Life Orb Starmie can't OHKO Skarmory either. Even with an EV spread focused more on Special Defense, Skarmory can still effectively block physical attacks. Skarmory can effectively set up Spikes against foes who run few Special Attack EVs, such as Vaporeon, Suicune, and some variants of Flygon. Skarmory can also switch in on special attackers who don't run Fire Blast or Thunderbolt, such as some variants of Togekiss, and Roost off the damage. Skarmory's Dragon-type resistance is another excellent asset for this set, as Skarmory is able to take Draco Meteors and Outrages from Dragonite and either set up Spikes or Roost off the damage, as Dragonite can't do much damage back at -2 Special Attack or locked into Outrage. Another great thing Skarmory has going for it is the Grass resist, so Celebi, Shaymin and Roserade provide Skarmory some excellent oppurtunites to get Spikes up. The moveset is mostly the same as the Physically Defensive set. Brave Bird is Skarmory's offensive move, Roost provides valuable healing, Spikes supports the team, and Whirlwind shuffles the opponent's team, adding Spikes damage and removing stat boosts.</p>
[ADDITIONAL COMMENTS]
<p>By running Stealth Rock over Brave Bird or Whirlwind, Skarmory can make a decent lead. He can easily get both Stealth Rock and / or Spikes up against slower, bulkier leads who can't hurt Skarmory, such as Metagross, Swampert, Tyranitar, and Hippowdon. If Skarmory has Brave Bird, he can also easily take out Machamp. This is mostly recommended for teams that like having Spikes up early on in the match.</p>
<p>The EVs are very similar to the Physically Defensive set, just with Special Defense EVs instead of Defense EVs to take hits from Pokemon that typically use special attacks.</p>
<p>Despite higher Special Defense, Skarmory still falls to special attackers who can hit Skarmory for super effective damage. Pokemon such as Heatran, Rotom-A, and Magnezone, as well as any other special attacker who runs Fire Blast or Thunderbolt, can easily switch in on Skarmory and force him out or set up. This variant of Skarmory likes to switch in and out based on resistances. Swampert is an excellent partner for Skarmory to have, as he resists Fire-type attacks, is immune to Electric-type attacks, and can set up Stealth Rock to complement Skarmory's Spikes. In return, Skarmory packs a 4x resistance to Grass-type attacks. Rotom-A doesn't resist Fire-type attacks, but it has an Electric-type resistance and Skarmory resists both of Rotom-A's weaknesses. Rotom-A also blocks Rapid Spin, which could otherwise eliminate the Spikes that Skarmory set up. Blissey is still a useful partner for Skarmory to have, as she can take the special attacks that Skarmory cannot handle.</p>
[SET]
name: Taunt
move 1: Taunt
move 2: Roost
move 3: Spikes
move 4: Whirlwind / Brave Bird
item: Shed Shell / Leftovers
nature: Careful / Impish
evs: 252 HP / 164 SpD / 92 Spe
[SET COMMENTS]
<p>Taunt is an interesting move for Skarmory to use. Although you are forced to give up both a moveslot and some bulk to utilize it to its full potential, Taunt gives Skarmory some nice new qualities. The main benefit is effectively dealing with opposing stall teams. Skarmory can easily outspeed and throw out a Taunt against other Skarmory, Blissey, Swampert, Hippowdon, and Celebi, and proceed to use Spikes. This is helpful for more offensive teams that like entry hazards up against stall teams as soon as possible. Another great technique that Skarmory can use with Taunt in his arsenal is stopping slow set-up sweepers. Although Skarmory can phaze away some set-up sweepers, late-game sweepers such as Calm Mind Suicune and Curse Snorlax can easily use Skarmory as set-up bait. With Taunt, however, they are unable to boost or recover and you can proceed to finish them off. Whirlwind has the benefit of phazing, but Brave Bird is useful if you don't want to be crippled by faster Taunt users.</p>
[ADDITIONAL COMMENTS]
<p>Much like the Specially Defensive set, this Skarmory set can function as a lead, getting early hazards in a similar manner to the Specially Defensive set whilst preventing Stealth Rock from being set up by slower leads. If you are using Taunt Skarmory as a lead, it is recommended that you use Lum Berry as his item. This allows Skarmory to take a Spore or Sleep Powder from Smeargle or Roserade, Taunt them to prevent them from using their sleeping move again, and prevent entry hazards from being set up.</p>
<p>The EVs let Skarmory outrun min Speed Gyarados and Taunt him before he can Sleep Talk. HP is then maximized, and the rest is put into Special Defense, though one can use a physically defensive spread if desired.</p>
<p>The partners for the above two sets work well with this set as well. This Skarmory can work on more offensive teams that need entry hazards up before stall teams do. It is recommended that you run some good Spikes abusers with Skarmory. Tyranitar is usually countered by grounded Ground- and Fighting-type Pokemon, meaning that he is quite capable of barrelling right through his counters with some Spikes support. Offensive Rotom-A can hurt the Flying-types immune to Spikes with STAB Thunderbolt while Spikes takes care of its grounded checks; it also blocks Rapid Spin. Dragonite is another good Spikes abuser due to his ability to cause switches and the number of grounded Steel-types who are Dragonite's main switch-ins.</p>
[Team Options]
<p>Skarmory can't be placed on any team; he needs proper support for his use to be completely worthwhile. This will usually come in two forms: extra residual damage like entry hazards and damaging weather, and resistances. Tentacruel is one of the most effective users of Toxic Spikes in OU, so he naturally pairs well with Skarmory. Roserade is another good Toxic Spikes users, though she is preferred on offensively-inclined teams. Hippowdon can provide a safeguard against physical attackers too powerful for Skarmory to handle, sandstorm support, and Stealth Rock, should Skarmory be lacking it himself. In general, you'll want strong defensive Pokemon who can set up health-chipping effects of their own, or who can simply take advantage of the ones Skarmory sets up with Roar or Whirlwind. In terms of resistances, Swampert is a great partner to Skarmory, as he is immune to Electric-type moves and is resistant to Fire-type attacks, both of which Skarmory fear. Lanturn resists these types similarly, but has the added advantage of actually benefiting from switching in on Electric-type moves thanks to Volt Absorb. Blissey, Cresselia, and other sturdy specially-based defenders work tremendously well alongside Skarmory, as they sponge normally fatal special hits directed at him.</p>
<p>If you are using an all-out offensive team, Skarmory may not be a suitable team member due to his lack of offensive presence. If you are using a team that isn't as fast-paced, Skarmory can be a valuable addition thanks to his ability to set up Spikes. If you are using a Pokemon who is usually countered by Pokemon who are grounded, setting up Spikes can allow said Pokemon to overpower his counters and proceed to sweep. The best choice for a Spikes-abusing sweeper is a Pokemon who carries moves that are capable of KOing Flying-types immune to Spikes. Tyranitar's powerful Stone Edge often scares out Flying-types, and Spikes harms Hippowdon and Swampert, who can wall Tyranitar. Rotom-A not only blocks Rapid Spin, but can wipe out Flying-types with Thunderbolt and can get past Heatran and Tyranitar with some assistance from Spikes. Jolteon packs a very powerful Thunderbolt to eliminate Flying-types and can use Spikes support to overpower Swampert and Tyranitar.</p>
[Optional Changes]
<p>Skarmory's more viable options have already been mentioned, but there are a few semi-usable moves available. Agility, Curse, and Swords Dance are available as boosting moves, but an offensive Skarmory is usually not worthwhile compared to stronger attackers like Metagross and Lucario. Roar is available as an alternative to Whirlwind should breeding be a problem, but it is usually not recommended, as Soundproof Pokemon like Mr. Mime will succeed in Baton Passing. Skarmory can run a set with Torment and Protect to get Spikes up easily on Heatran and stall teams, but he is very vulnerable to being set up on and is generally outclassed by the Taunt set against stall teams. In a similar vein, Steel Wing is an alternative move choice to nail Tyranitar and Rhyperior; however, it makes it even easier for Pokemon like Lucario, Heatran, and Infernape to switch in (not to mention its low Base Power). Rest is not recommended on any defensive set lacking Sleep Talk, since Skarmory will essentially be dead weight on your team for two turns.</p>
<p>If Skarmory is faster than the opposing Pokemon, it can use Roost to remove its Flying type for the turn and potentially make an attack aimed at Skarmory weaker. Therefore, you always have the option of increasing Skarmory's Speed so he can outspeed certain foes and Roost to soften their attacks. How much Speed Skarmory should run mainly depends on what your team struggles against and what is popular in the metagame at the moment. You should not go overboard with the amount of Speed however, because that will take too much out of Skarmory's defensive capabilities to be worth it.</p>
<p>Always use Keen Eye on Skarmory over Sturdy if used in competitive play, because OHKO moves are banned, but Sand-Attack is not.</p>
[Counters]
<p>Skarmory will most likely lose to unresisted special attacks, unless he is specially defensive, and will take a particularly large amount of damage from those that are super effective. Electric- and Fire-type special attackers with a super effective STAB move can usually 2HKO, or even OHKO, depending on EV investment. Heatran in particular gets a safe switch-in because of his resistance to Skarmory's STAB attacks, and can threaten him with with a Fire-type move of his own.</p>
<p>Strong stat-uppers with neutral STAB attacks like Lucario, Gyarados, Rhyperior, and Tyranitar will usually come out on top against Skarmory, provided he doesn't just Whirlwind them away before they have a chance to attack.</p>
<p>Magnezone is the bane of Skarmory's existence; with its Magnet Pull ability, Magnezone prohibits Skarmory from switching out (unless Skarmory is holding Shed Shell), and can proceed to KO Skarmory with Thunderbolt.</p>
