Overview

Qwilfish is a neat UU Pokemon who can support a team by either taking down opponents by sacrificing itself or attempting a sweep. It doesn't have the power of other Swift Swim sweepers like Kabutops and Gorebyss, but it has plenty in its movepool to offer. Its ability to soak up Toxic Spikes, higher Speed, and access to Explosion are the main things that differentiate it from Kabutops; additionally, it can also beat most Milotic. When rain is up, this is one Pokemon whom you shouldn't underestimate.

Swords Dance

Life Orb Swift Swim Adamant / Jolly
Moveset EVs
~ Swords Dance
~ Waterfall
~ Poison Jab
~ Explosion
252 Atk / 4 Def / 252 Spe

This set plays like a less powerful but slightly faster version of Kabutops. One of the big advantages Qwilfish has over Kabutops is its ability to absorb Toxic Spikes, which can badly hurt your team's ability to sweep. Waterfall is its main attack option, its power boosted by 1.5x by the rain. Poison Jab is its secondary attack to hit Grass- and Water-types that resist Waterfall. Explosion takes out anything that doesn't resist it after a Swords Dance boost. Return is an alternate option for use over Explosion as it can hit Quagsire, Gastrodon, Toxicroak, and other Water- and Poison-type resists without blowing Qwilfish up; however, Explosion's sheer power and ability to blow holes in teams is generally preferred. Qwilfish does well against almost all Milotic thanks to resisting Surf and being neutral to Hidden Power Grass. This is a great asset to Rain Dance teams since Milotic can wall many other rain sweepers.

Spikes Lead

Focus Sash Jolly
Moveset EVs
~ Spikes
~ Explosion
~ Taunt / Aqua Jet
~ Waterfall
4 HP / 252 Atk / 252 Spe

This set's main focus is to set up as many layers of Spikes as possible. With 295 Speed, Qwilfish will often be able to set up at least one layer of Spikes and then explode, ideally against the opponent's Spinner. Waterfall allows Qwilfish to break Focus Sashes before using Explosion and acts as a reliable STAB move. Taunt and Aqua Jet both work well on this set for very different purposes. Taunt allows Qwilfish to reliably stop an opponent from setting up with bulky leads such as Omastar, Cloyster, and Rhyperior. Aqua Jet allows Qwilfish to beat Moltres and Alakazam more reliably. Taunt is recommended because it cannot get Spikes up against Moltres and Alakazam and still beat them, so it's often better to have a reliable switch-in; however, keep in mind that they are both quite difficult to switch into.

Rain Dance Lead

Damp Rock / Focus Sash Swift Swim Adamant / Jolly
Moveset EVs
~ Rain Dance
~ Waterfall
~ Poison Jab / Taunt
~ Explosion / Destiny Bond
4 HP / 252 Atk / 252 Spe

Qwilfish can make a decent Rain Dance lead. The idea is to set up Rain Dance and attempt a sweep of its own, or to explode Qwilfish on someone and send in your secondary Swift Swim abuser unharmed. Waterfall is Qwilfish's main attack again. Poison Jab is better for sweeping and hits the Grass-type Pokemon who resist Qwilfish's main attack, but Taunt has its uses, too. For example, it can prevent opponents from setting up a Substitute or Stealth Rock or throwing status around, which can harm a team member's chance of sweeping. However, Qwilfish is quite slow, meaning Taunt is only useful against slower, bulkier leads unless rain is up. Explosion is the preferred option in the last slot to go out with a bang, but Destiny Bond can be used instead to force opponents to switch or faint, and due to Rain Dance, Qwilfish will be be faster than them.

Offensive Spikes

Leftovers Poison Point Adamant
Moveset EVs
~ Spikes
~ Waterfall
~ Poison Jab / Taunt
~ Explosion / Destiny Bond
252 HP / 252 Atk / 4 Spe

Although one of its lesser options, Qwilfish can still make a great Spikes user. The handy thing about Qwilfish is that five of the best Rapid Spinners in UU have trouble switching into it, allowing Qwilfish to set up quite easily. Claydol, Donphan, Sandslash, and Torkoal are all weak to Waterfall, and are therefore unlikely to switch in, while Blastoise has trouble doing any real damage and gets worn down by Poison Jab.

Waterfall is the main attacking option for Qwilfish, while Poison Jab helps against Grass-types and certain Flying-types who resist or are immune to Water-type attacks, like Mantine and Altaria. Although Qwilfish doesn't have stellar defenses, it can use Taunt over Poison Jab to stop opponents from setting up. For the last slot, Explosion is the preferred option to go out with a bang, but Destiny Bond is a good alternative and might cause some switching if you reveal it early. Thunder Wave is a minor option, but if your team is slow, it could be helpful, and with the 20% flinch rate of Waterfall, Qwilfish can be an annoyer of sorts. Although Qwilfish may seem outclassed by Omastar as a Spikes user, its access to Explosion, Taunt, and higher Speed are some big things which set it apart from Omastar. It can also soak up Toxic Spikes, which stall teams hate.

Defensive Spikes

Leftovers Poison Point Impish
Moveset EVs
~ Spikes
~ Pain Split
~ Poison Jab
~ Taunt / Aqua Jet
248 HP / 152 Def / 104 SpD / 4 Spe

With this set, Qwilfish is able to switch into the majority of Water- and physical Fire-types and defensive Pokemon and easily lay down Spikes. Pain Split lets Qwilfish survive longer and therefore set up more layers of Spikes. Poison Jab is your chosen STAB move as it lets Qwilfish hit other Water-types, such as SubPunch Azumarill (whose Substitute will be broken by it), and with Qwilfish’s bulk, it will easily take its hits from Azumarill's common attacks, except for Normal-type attacks. In the last slot, Taunt is the preferred option to stop opponent's from using recovery and also lets Qwilfish easily beat both SubRoost Moltres and Articuno. However, Aqua Jet is a reasonable replacement to revenge kill weakened Blaziken, Dugtrio, and Houndoom.

While many people would prefer to use Cloyster or Omastar for Spikes, Qwilfish does have some notable advantages over those three. Firstly, due to its Poison typing, it absorbs Toxic Spikes upon entry, and so stops your team from being slowly weakened by the poison. Because of this, it can also relieve your team of reliance on Aromatherapy or Heal Bell support. This Poison typing also means Qwilfish is immune to Toxic, letting it take on defensive Pokemon such as Chansey better than the aforementioned three Pokemon. Qwilfish also has an easier time setting up against bulky Water-types and can wall most Fire-types. It also can do very well against Stallrein since it can Taunt Walrein and resists Water-type attacks, unlike Omastar and Cloyster.

Other Options

Toxic Spikes is an option over Spikes, although in UU, there are many Poison-types who can easily absorb them. There's Endure / Substitute and Flail, but that is better left to Kabutops. Counter is rather gimmicky and should only be used with a Focus Sash, but it could surprise some Pokemon. Anything else of note requires Qwilfish to take a hit or be slow (Revenge, Payback, Gyro Ball), which is definitely not acceptable. Aqua Jet is another option, as priority is very useful in UU, but this makes it generally outclassed by Kabutops, who has a higher Attack stat. Also, Aqua Jet + Swords Dance is an illegal move combination, so this further prevents Qwilfish from using it too effectively.

Checks and Counters

Quagsire and Toxicroak are effective general counters, as they are immune to Water-type moves because of Water Absorb and Dry Skin, respectively, and both resist Poison-type moves. Walrein, Gastrodon, and Cradily with Earthquake will also be effective, although a +2 rain boosted Waterfall is going to hurt both Cradily and Gastrodon. Most healthy Pokemon with decent defenses will be able to take a hit if they're not weak to Water- or Poison-type attacks. Milotic and Lapras are some examples of such Pokemon, although Milotic will need Hidden Power Electric and Lapras will need Thunderbolt. Furthermore, Qwilfish's Speed is noticeably average, so the non-Rain Dance version can be outsped and hit with strong attacks from Choice item users.
