Moves
Swords Dance bolsters Shiftry's Attack stat, allowing it to hit incredibly hard. Knock Off is Shiftry's most powerful and reliable attack, hitting foes for great damage while also removing their item. Seed Bomb hits many Pokemon that resist Dark hard while also bypassing Unaware Quagsire. Sucker Punch gives Shiftry powerful priority, threatening to OHKO a large majority of faster foes after a Swords Dance boost. If Shiftry is used on a sun team, Shiftry may consider Explosion over Sucker Punch. Explosion, especially if boosted by Swords Dance, can obliterate foes and provide a free switch for a sun sweeper or sun setter. If Explosion is used, Shiftry can now run Leaf Blade which is otherwise incompatible with Sucker Punch.
Set Details
Maximum Attack and Speed investment is used to maximize Shiftry's offensive potential. An Adamant nature further boosts Shiftry's power, while a Jolly nature allows Shiftry to outrun neutral-natured base 80 Speed to base 90 Speed Pokemon such as Zangoose, Kangaskhan, Magmortar, Mesprit, and Kabutops, while Speed tying positive-natured Mesprit, Kabutops, and opposing Shiftry. Life Orb further increases Shiftry's damage output, but Black Glasses is a fine alternative, as Shiftry will usually be relying on the damage output of its Dark-type moves, especially after a boost, than its Grass-type attack. Lum Berry is also an option on Shiftry to reliably set up on Scald users while staving off status ailments in general, such as those from Will-O-Wisp, Toxic, and Thunder Wave. Chlorophyll is the ability of choice if one is considering using or combating sun teams, whereas Early Bird can sway the matchup against Jynx in Shiftry's favor.
Usage Tips
This Shiftry variant is more inclined to go for the sweep as opposed to pivoting in and out, but it can also soften its checks early-game with Knock Off so that they succumb to Swords Dance-boosted attacks later on. However, against physically bulky Pokemon that resist Grass, such as Garbodor, Vileplume, Weezing, and defensive Rotom-S, it might be wise to not prematurely use an unboosted Knock Off on them in order to avoid weakening future uses of Knock Off. Instead, Shiftry should try to nail them with a +2 fully powered Knock Off and drop them in a single blow; however, all four of them require some prior damage, preferably from Stealth Rock, in order to achieve this.
Shiftry can find setup opportunities by threatening the numerous slower Pokemon weak to its dual STAB attacks. This Shiftry set also functions well under sun. If Explosion is used, it is best used on the final turn of sun, as Shiftry is not expected to continue its sweep without Sucker Punch or Chlorophyll to augment it. Be warned that using Leaf Blade will alert opponents that Shiftry lacks Sucker Punch, so it isn't advised to reveal Leaf Blade if sun isn't up.
Team Options
Fire-types such as Pyroar and Magmortar make for great offensive partners, plowing through most of the Pokemon that give Swords Dance Shiftry trouble, such as Mawile, Vileplume, Weezing, and Pawniard; Shiftry, meanwhile, can set up on the Water-, Rock-, and Ground-types that the Fire-types lure in. Ground-types are also good teammates, as they can take down Garbodor, Skuntank, and defensive Mawile with ease while offering strong offensive presence in return; Rhydon, Golurk, and Piloswine can all set up Stealth Rock for Shiftry and help weaken the opponent's physical walls, and Rhydon and Golurk can even threaten the opposing team with their own form of setup. Fighting-types are solid Pokemon to use alongside Swords Dance Shiftry, as their combined offensive potency can put immense pressure on teams. They also resist Bug- and Rock-type moves for Shiftry while Shiftry can handle their Psychic weakness. Thick Fat Hariyama can shield Shiftry against problematic Fire- and Ice-type attacks. Psychic-types can defend Shiftry against Fighting-types while also handling problematic Poison-types for Shiftry; the likes of Mesprit and Mr. Mime can also provide Healing Wish support to give Shiftry a second shot at sweeping. Sun-setting teammates, such as Regirock, Mesprit, and Liepard, as well as sun sweepers, such as Victreebel, Pyroar, and Jumpluff, are also fine partners for Shiftry if one intends to have Shiftry sweep with the help of Chlorophyll.
