Level 100 Statistics (see level 5, 50, 100)
Huntail is an unfortunate Pokemon. He's stuck in a sea of Water-types who share his ability, Swift Swim, and has no shining stat or quirk to separate him from the pack. As a physical rain sweeper, Huntail is generally outclassed by the likes of Kabutops, Qwilfish, and Ludicolo; as a special rain sweeper, he's outclassed by Omastar and his pink counterpart, Gorebyss. Huntail, however, has one saving grace available to him: his ability to act as a mixed rain sweeper.
This set is designed for Huntail to come in late-game and finish off the remainder of an opponent's team, hitting the final few Pokemon in their weaker defensive stats. In order to be effective, Huntail needs to have rain falling, which not only doubles Huntail's awful Speed with Swift Swim, but also increases the power of his STAB moves.
Aqua Tail is Huntail's strongest physical STAB move, and with it, he can 2HKO 252/0 Registeel and OHKO Chansey after Stealth Rock. Waterfall can be used instead if you're worried about accuracy issues; however, it misses out on many KOs that Aqua Tail provides, making it an inferior choice. Ice Beam is for any Grass-type who would otherwise wall Huntail, such as Tangrowth and Leafeon, dealing an OHKO to each after Stealth Rock. A combination of Aqua Tail and Ice Beam also KOes 252/252 Calm Venusaur. Hydro Pump deals a clean 2HKO on physically defensive Uxie and Registeel, who would normally wall this set entirely. Hidden Power Grass is for weaker Water-types who would normally have their way with Huntail; however, it still isn't strong enough to break through bulkier Water-types, such as Milotic, Blastoise, Poliwrath, and Slowking.

Unlike the previous set, this one focuses on Huntail's higher base 104 Attack stat. While offensively weaker than Kabutops, Huntail sports better typing and a way to bypass bulky Grass-types. Because of this, Huntail and Kabutops can be used on the same team, with Huntail softening up the opposing team and Kabutops coming in later to finish the job. Aqua Tail and Double-Edge provide Huntail with the awesome type combination of Water / Normal, resisted only by Shedinja in UU. Ice Beam is for any bulky Grass-types who are bull-headed enough to think they can counter this set. Crunch makes an appearance on this set to allow Huntail to dispose of Slowking and also deals decent damage to his counterpart, Slowbro. Sucker Punch gives Huntail some use outside of rain and is a nice way to hit Pokemon like Scarf Rotom or Mismagius, who would otherwise outpace Huntail even in the rain and KO with Thunderbolt.
Team Options & Additional Comments >>>
Huntail doesn't have many other moves available to him. Super Fang has its merits on both sets, allowing Huntail to strip his counters, such as Milotic and Toxicroak, of half of their health, which can let someone like Ludicolo or Gorebyss to come in without taking damage and finish the job. Huntail also has access to Bounce, which grants Huntail the great type combination of Water/Flying, though the lack of STAB and the two turns required to use it usually leave it out of favor to moves like Return or Double-Edge. Huntail has Baton Pass, but can only pass Iron Defense and Substitute. Hidden Power Psychic can be used to annihilate Toxicroak and get a strong hit in on Poliwrath, but the other moves listed are usually more helpful.
Checks and Counters
Bulky Water-types, such as Milotic, Blastoise, Poliwrath, Slowbro, and Slowking, have little trouble with either of Huntail's sets and take little damage from Hidden Power Grass. Milotic and Slowbro/Slowking don't even mind Super Fang as they can just recover off the damage and continue to whittle down Huntail's health. Toxicroak can take anything from the Mixed Sweeper set and Swords Dance or Nasty Plot in Huntail's face. However, Toxicroak takes massive damage from Double-Edge on the Physical Sweeper set, and Huntail can surprise Toxicroak with Hidden Power Psychic for an OHKO.
Physically defensive Uxie and Registeel take little damage from anything from the Physical Sweeper set, but both take massive damage from Hydro Pump on the Mixed Sweeper set. Gardevoir with Trace and Golduck with Cloud Nine can both end Huntail's sweep. Gardevoir cannot switch into both Stealth Rock and Aqua Tail, but can outspeed Huntail once in and KO with either Thunderbolt or Energy Ball. Golduck can 2HKO Huntail with Hidden Power Grass if he switches into Aqua Tail and Encores it; however, if Golduck switches into Double-Edge or Hidden Power Grass, he will be KOed before he can KO Huntail. Electrode can outpace the Mixed Sweeper set and OHKO with Thunder or Thunderbolt, but unless he runs maximum Speed, he will be outsped by the physical sweeper and take massive damage from Aqua Tail before KOing Huntail. Scarf Rotom and positive Speed Scarf Venusaur can both outrun either set and OHKO Huntail with Thunderbolt or Leaf Storm respectively; however, Rotom must be wary of Sucker Punch and Venusaur will be maimed by Ice Beam if he switches into it.
