Overview

Qwilfish is a curious little puffer fish. On one hand, it has mediocre stats and paper-thin defenses, popping at a single touch. On the other hand, it has assets that other Pokemon could only dream of having. With its Swift Swim ability, Qwilfish becomes the fastest Spiker in the rain, while access to Taunt, Explosion, and Destiny Bond allow it shut down numerous walls. Its Poison typing means that it can absorb the dreaded Toxic Spikes that plague many Ubers. With Swords Dance, Qwilfish can also become a deadly sweeper. Play Qwilfish to its strengths, and it will not disappoint.

Utility

Splash Plate / Life Orb Swift Swim Jolly
Moveset EVs
~ Spikes / Toxic Spikes
~ Taunt
~ Waterfall
~ Destiny Bond / Explosion
4 HP / 252 Atk / 252 Spe

This set aims to abuse as much of Qwilfish's support options as possible. This set can set up entry hazards, break stall, revenge kill, and even clean up weakened teams. The main idea is to switch Qwilfish into a wall that cannot hurt it, such as Blissey and Lugia. Qwilfish can then Taunt said wall, preventing it from using its support moves, and then set up entry hazards for free. When Qwilfish is low on health, simply use Destiny Bond or Explosion to bring the opponent down with it. Qwilfish also has the added bonus of absorbing Toxic Spikes upon switching in, which is a boon for teams with Pokemon susceptible to them, such as Kyogre and Palkia. Make sure to keep Qwilfish alive to reabsorb Toxic Spikes if they are likely to be up again.

Spikes and Toxic Spikes are the two entry hazards that Qwilfish can set up. Choose the appropriate entry hazard that suits your team. Taunt allows Qwilfish to shut down walls. Waterfall is Qwilfish's preferred STAB attack, and is surprisingly powerful in the rain, capable of 2HKOing Garchomp. It can also revenge kill frailer, weakened threats, such as Darkrai and Mewtwo, and clean up late-game. Destiny Bond is preferred over Explosion because Qwilfish's Explosion fails to KO Groudon and Giratina, two of Qwilfish's biggest counters. However, Explosion can still be used since setup sweepers can potentially set up on Destiny Bond.

Swords Dance

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

With a passable base 95 Attack, Swords Dance, and doubled Speed with Swift Swim, Qwilfish can become a deadly sweeper given the opportunity. After a Swords Dance, rain-boosted Waterfall obliterates almost everything that does not resist it, while Poison Jab and Explosion destroy most of the Pokemon that do.

Lead

Focus Sash Swift Swim Adamant
Moveset EVs
~ Payback
~ Aqua Jet
~ Toxic Spikes / Spikes
~ Explosion / Destiny Bond
4 HP / 252 Atk / 252 Spe

While this set seems awkward, Qwilfish can be a surprisingly effective lead in the Uber metagame. With Payback and Aqua Jet, it can easily 2HKO Deoxys-S, limiting it to one layer of entry hazards at most. Against bulkier leads, such as Groudon, Dialga, and Kyogre, it can usually set up one layer of hazards and Explode or set up two layers and die. It can always set up two layers against Kyogre, since Swift Swim allows it to outspeed even Choice Scarf Kyogre. The choice of entry hazard depends on your team. More offensively based teams tend to prefer Spikes, while Toxic Spikes suits defensive teams better. Explosion is the suicide move of choice as it prevents Forretress from spinning away one layer of Spikes. However, Destiny Bond can be used to surprise Groudon and Dialga leads, which Explosion would not OHKO.

Other Options

Qwilfish doesn't really have many other options to use in Ubers, due to its relatively poor stats. Aqua Tail can be used over Waterfall for more power at the cost of some accuracy. Return is a viable option for neutral coverage in place of Explosion. Haze quickly wipes away boosts in a pinch, but it is quite useless otherwise. Finally, a Choice Band set with Waterfall, Aqua Jet, Poison Jab, and Explosion can also be used to decent effect.

Checks and Counters

Rayquaza outspeeds Qwilfish and OHKOs it with almost any attack. It resists Waterfall, does not take much from Poison Jab, and only needs to watch out for Explosion. Groudon, Dialga, Giratina, and Giratina-O completely wall Qwilfish unless it uses Destiny Bond, but the former two must watch out for Swords Dance-boosted Explosion and Giratina cannot stop Qwilfish from setting up entry hazards. Just hit Qwilfish really hard, and it will not trouble you very much.
