[SET COMMENTS]
<p>While Scizor may be slow, its access to Bullet Punch (which deals more damage than Rayquaza’s ExtremeSpeed), superb typing, and Roost set it apart from Rayquaza and Lucario. Another significant selling point of Swords Dance Scizor as a late game sweeper is that it can easily set up on Forretress, a Pokémon who normally gives Scizor trouble.</p>
<p>After one Swords Dance, Scizor is capable of OHKOing Pokemon such as Darkrai, Shaymin-S, and even Rayquaza with Bullet Punch after Stealth Rock damage. Roost is incredibly useful on this set. Scizor's typing gives it many opportunities to heal against or potentially set up on foes, such as Choice Scarf Pokemon locked into a resisted attack, as well as defensive Pokemon, such as Forretress and Blissey. For the last move, Bug Bite is the main choice, as it ensures that Scizor will easily OHKO Wobbuffet after a Swords Dance, as well as Mewtwo, Latias, and Latios before a Swords Dance. Scizor can also easily 2HKO even the bulkiest Groudon, and will even OHKO 4/0 Groudon after Spikes or Stealth Rock damage (if you have Life Orb). Superpower can be used to hit Dialga, as well as OHKO Heatran on the switch before a Swords Dance. Finally, Scizor can use U-turn to scout with early on in the match before sweeping once the opponent's Steel-type resisters are KOed.</p>
[Additional Comments]
<p>Here are some damage calculations to show Scizor's power. All of these damage calculations assume that Scizor has used Swords Dance once, and is either carrying Life Orb or Metal Coat.</p>

<p>As you can see, Stealth Rock support is highly recommended for Scizor, because it relies on it to gain several KOs after a Swords Dance. Spikes and Stealth Rock support together is also welcome, as this will allow Life Orb Scizor to always OHKO Garchomp with a +2 Bullet Punch, while Metal Coat Scizor will always OHKO Mewtwo with a +2 Bullet Punch.</p>
<p>Scizor has several viable items to choose from: Life Orb, Metal Coat, and Leftovers. Each of them have some specific advantages and disadvantages. Life Orb will grant Scizor the most power. In addition to boosting the power of Bullet Punch, it will also boost the power of Scizor's other attacks. This is especially useful against Lugia, as the extra power Life Orb grants Bug Bite will allow Scizor to sometimes OHKO Lugia after it takes Stealth Rock damage. Even if Lugia puts up Reflect, Bug Bite will still do enough damage to force Lugia to restore its health with Roost, thus allowing you to KO it in its Bug-type-weak state. While Metal Coat won't offer as much power and doesn't boost anything other than Bullet Punch, its main advantage over Life Orb is the lack of recoil, thus allowing Scizor to last longer on the battlefield (which is especially important if Scizor is your main Dragon-type resister). This is particularly useful if you decide to use U-turn, as the recoil from Life Orb and entry hazards can quickly drain Scizor of its health. Finally, if you are content with losing more KOs, Leftovers can be a good choice to give Scizor more survivialbility.</p>
<p>Swords Dance Scizor's biggest foes are Pokemon who resist Bullet Punch and can hit back with a Fire- or rain-boosted Water-type attack. This means that Palkia, Dialga, Kyogre, Ho-Oh, and Heatran will usually shut Scizor down effectively. If you use Life Orb Scizor you can use Bug Bite on the switch; it will deal such a massive amount of damage to Palkia and minimum HP Kyogre that they will almost always be in the KO range of Bullet Punch after Stealth Rock damage. In a similar manner, if you decide to use Superpower, you can OHKO Dialga and Heatran switch-ins. Thunder Wave Kyogre can easily switch into Heatran and Ho-Oh's Fire-type attacks with some Speed investment, and OHKO them with Surf. It can also paralyze Palkia, allowing you to OHKO with a +2 Bug Bite or Superpower. In a similar vein, Latias can easily switch into Kyogre, Palkia's non-Dragon-type attacks, or even set up on Choice Scarf Heatran. Garchomp can easily OHKO Heatran, Palkia, and Ho-Oh with Earthquake, Outrage, and Stone Edge respectively, as well as dealing massive damage to Dialga with Earthquake. Finally, a Heatran of your own can defeat most Dialga, and take advantage of Choice Scarf Palkia's Fire-type attacks (watch out for Surf in the rain, though).</p>
