[OVERVIEW]
<p>Swellow is fast. Really fast. However, Swellow is a struggle to use early-game because Steel- and Rock-types can easily force it out, and if the opponent has Stealth Rock, then Swellow's HP can dwindle quite quickly, rendering it ineffective. It's not all bad news though, the amazing Speed it has enables Swellow to become an excellent sweeper late-game, since it can outrun just about everything in UU unboosted. With STAB 140 Base Power Facade and Brave Bird added to the mix, Swellow becomes one of the premier threats in UU. Though Swellow's movepool is very limited, this is more than made up for by its capability to hit hard and fast with what it has.</p>

[SET COMMENTS]
<p>This set is designed to take advantage of Swellow's ability, Guts. Swellow is a fearsome sweeper late-game, with excellent Speed and access to strong STAB attacks. Thanks to Toxic Orb, Facade has 140 Base Power, and is a great move when paired with the ability Guts, while Brave Bird allows you to hit the Ghost-types that Facade cannot. Brave Bird will 2HKO both Spiritomb and Rotom that don't invest heavily in Defense, as well as OHKO Mismagius. Protect is a great move if you decide to use Swellow as a lead. It allows you to activate Guts without any risk and scout with a more powerful U-turn. Quick Attack, however, hits faster Pokemon, such as Electrode or a Choice Scarf Pokemon, and allows Swellow to revenge kill and activate Guts in one fell swoop; killing two birds with one stone so to speak. Pursuit will allow you to hit fleeing Mismagius, Rotom, and Chansey.</p>
<p>Toxic Orb does less damage to Swellow for the first two turns it is out, but on the third turn, it is tied with Flame Orb for total damage done. If you think you can keep Swellow in for more than three turns, you'll want to use Flame Orb, otherwise, use Toxic Orb. The EV spread is a simple spread to take advantage of Swellow's highest stats and maximize its ability to sweep.</p>
[ADDITIONAL COMMENTS]
<p>This set is perfect for destroying teams late-game and taking care of the more fragile Pokemon in UU, but it is completely walled by Steel- and Rock-types. Swellow works great alongside Magneton, who can come in on Rock-, Electric-, and Ice-type attacks and trap Steel-types. Fire-types like Blaziken, Houndoom, Typhlosion, and Magmortar can also force Steel-types out, but be careful not to switch any of the last three into a Rock-type attack aimed at Swellow. Nidoqueen and Nidoking can also scare away Rock-types with their powerful STAB. Defensively, a good partner to take out Rock-types for Swellow is Hitmontop, whose access to Intimidate will enable it to efficiently take the physical attacks directed at Swellow. Hitmontop also has access to Rapid Spin, which helps Swellow by removing Stealth Rock, thus increasing Swellow's survivability. Steel-types in general can come in on attacks directed at Swellow. Perfect candidates for this job would be would be Steelix and Registeel. Steelix has a great typing which enables it to come in comfortably on Rock and Electric attacks. Registeel is another option due to the tremendous bulk it has on both sides. Dugtrio is a true blessing for Swellow due to its exclusive ability to trap Rock- and Steel-types. Swellow's U-turn can safely bring in Dugtrio to trap the opponent's Pokemon if used on the switch.</p>

[SET COMMENTS]
<p>This set has potential and is very simple to use. If you manage to come in on Toxic or Will-O-Wisp you will activate Guts, which allows you to boost your Attack to a greater extent with Life Orb. Your main STAB options are Return and Facade. If you are sure you can come in on a status attack, then Facade is appealing for its higher power output; however, Return is more reliable and has a relatively high Base Power regardless of whether you manage to switch into status or not. For example, Return OHKOes Manectric after Stealth Rock, whereas an unboosted Facade falls short. U-turn is to scout for incoming Steel- and Rock-types so that you can switch to an appropriate counter. Quick Attack is preferred to hit Choice Scarf users while Pursuit traps weakened Mismagius, Rotom, and Chansey.</p>
[ADDITIONAL COMMENTS]
<p>This set is walled by Steel- and Rock-types. Magneton traps Steel-types, while Fighting-types threaten both Steel- and Rock-types, often causing them to switch out. Fire-types can also come in and force Steel-types to switch out. Blaziken is a good candidate because it has access to both STAB Fire- and Fighting-type moves to scare away Swellow's counters. Dugtrio can remove Steel- and Rock-types early in the match, allowing Swellow to sweep without breaking a single sweat.</p>
[Team Options]
<p>Swellow's biggest obstacles when it comes to sweeping are Rock- and Steel-types. Any Pokemon who can easily remove these Pokemon, such as Dugtrio or Milotic, will be Swellow's best friend. A good U-turn partner to pair with Swellow is Primeape. Swellow easily draws out threats such as Aggron and Registeel whom Primeape can easily OHKO with Close Combat. In return, Swellow can absorb any status attacks aimed at Primeape, and threaten the Ghost-types that may switch into Primeape's Close Combat. Swellow works wonders in the late-game when many of the opponent's walls have been weakened. A good way to ensure that they have been softened up is to set up entry hazards such as Stealth Rock and Spikes. Good candidates to set up these entry hazards include Cloyster, Omastar, Uxie, or Qwilfish. Uxie makes another good U-turn partner for Swellow as well, and can even set up dual screens to give Swellow a little more protection against priority attacks. Cloyster and Qwilfish threaten most of the Rock- and Steel-types that wall Swellow and can use Explosion on walls that Swellow would normally only be able to 2HKO, such as Milotic or Weezing.</p>
[Optional Changes]
<p>A SubPassEndeavor set consisting of Substitute / Baton Pass / Endeavor / Return can be used, with a pinch Berry of your choice, but this set leaves Swellow utterly exposed to priority moves, and with Return as its only attacking option, Swellow has little hope against Rock- , Ghost-, or Steel-types. Sleep Talk is an option to absorb sleep, but Facade does not get the boost it does from other status conditions, so Return is a more reliable move in this case. Steel Wing is another option to hit Rock-types, but it is too feeble to dent even the least defensive of Rock-types in UU. Roost can be used to replenish health, but Swellow will find little opportunity to use it with its low defensive stats, and will likely lose too much health from Stealth Rock, status, and Brave Bird recoil to make it useful.</p>
[Counters]
<p>As stated in the additional comments section for both sets, Swellow is walled by most Rock- and Steel-types. Aggron, Probopass, Steelix, Rhyperior, Relicanth, and Registeel are all good examples of counters. Ghost-types can come in on Normal-type attacks, but switching into Brave Bird will OHKO most of them (Rotom is 2HKOed, despite resisting Flying-type attacks). Priority moves combined with residual damage can often lead to a KO thanks to Swellow's poor defenses.</p>
