I decided to update my Gen 7 swift swim monotype team to make it compatible with SS, as well as taking advantage of the new pokemon in Gen 8.

Dracovish @ Choice Scarf
Ability: Strong Jaw
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Fishious Rend
- Outrage
- Psychic Fangs
- Leech Life
Dracovish is the breaker of the team, with its setup designed to outspeed both potential walls and sweepers, and thus maximize the damage from Fishious Rend. Strong Jaw increases the power of both Fishious Rend and Psychic Fangs, with the latter move mostly being used against fighting type pokemon. Outrage is included in the move set as it is a STAB move for Dracovish, while Leech Life helps Dracovish regain some HP and last longer.

Azumarill @ Sitrus Berry
Ability: Huge Power
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Belly Drum
- Aqua Jet
- Knock Off
- Play Rough
Azumarill is a great set-up sweeper for the team, as huge power combined with Belly Drum allow it to have 4x power. Play Rough allows Azumarill to be a major pain for dragon, fighting, and dark pokemon, as Azumarill's high damage allows it to OHKO when super-effective. Aqua Jet allows for priority attacking and is excellent for finishing off faster injured pokemon, while Knock Off helps remove important items from enemy pokemon.

Seismitoad @ Life Orb
Ability: Swift Swim
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Hydro Pump
- Earth Power
- Stealth Rock
- Focus Blast
Since mega swampert does not exist in SS, Seismitoad is an essential fill-in, with its immunity to electric attacks and its ground moves. While Seismitoad can be used as a lead, due to its stealth rocks, it is best to bring it in after rain dance has been summoned and swift swim has doubled Seismitoad's speed. Earth power was mainly included to damage electric pokemon, while Hydro Pump provides an extra STAB move and Focus Blast adds a fighting move that is especially useful against steel pokemon.

Keldeo @ Choice Specs
Ability: Justified
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Aura Sphere
- Hydro Pump
- Icy Wind
- Scald
Keldeo was added to the team to act as a special set-up sweeper, while azumarill acts as a physical set-up sweeper. Aura Sphere is a powerful STAB move that effectively checks most normal, rock, dark, steel, and ice pokemon, especially with the special attack boost from choice specs. Hydro Pump acts as a powerful STAB move against full health pokemon, while Scald is more effective for finishing pokemon and avoiding misses in crucial situations. Icy wind helps Keldeo counter flying pokemon, especially slower flying pokemon or those that are injured.

Barraskewda @ Choice Band
Ability: Swift Swim
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Waterfall
- Close Combat
- Psychic Fangs
- Crunch
Barraskewda is an excellent sweeper once major threats have been neutralized and rain dance is active, thanks to its immense attack stat that is boosted by choice band and its excellent speed that is boosted by swift swim. Waterfall acts as the main weapon for Barraskewda, due to it being a STAB move for water pokemon. The other moves allow Barraskewda to act as a secondary breaker and check various pokemon, including Ferrothorn with Close Combat, Dragapult with Crunch, and poison pokemon like Toxapex with Psychic Fangs.

Pelipper @ Choice Scarf
Ability: Drizzle
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Hydro Pump
- Hurricane
- U-turn
- Ice Beam
Pelipper is a great lead due to its drizzle ability that summons rain dance, which is essential for swift swim pokemon like Barraskewda and Seismitoad. Using choice scarf instead of damp rock allows Pelipper to act as a viable utility pokemon, especially since Hurricane doesn't miss in rain and thus acts as a viable flying move. Hydro Pump was included as it is a STAB move for Pelipper, while U-turn allows for a fast pokemon switch, and Ice Beam helps damage grass and dragon pokemon.
THREATS
Grass Teams - Grass teams can severely damage this team, mainly because 5 out of the 6 pokemon are weak to grass.
Fairy Team - Fairy teams can also prove dangerous for this team, as no pokemon has steel or poison moves and both Dracovish and Keldeo are weak to fairy.
Trick Room - Teams running trick room are very dangerous for this team, due to most pokemon on the team being designed to outspeed opponents.
Any advice would be greatly appreciated.

Dracovish @ Choice Scarf
