Whiscash has to be the coolest fish in the tier; Stunfisk doesn't even stand a chance. Of course, coolness doesn't correlate with battle-prowess, so for the most part Whiscash is rarely seen in the metagame over its counterpart Seismitoad. However, the recent tier changes provide Whiscash with its chance to shine; with Slowking and Lanturn being gone, the number of bulky Water-types is ever shrinking. Furthermore, Whiscash now has access to Hydration, letting defensive sets run Rain Dance + Rest for semi-reliable recovery and finally giving Whiscash some use as a defensive Pokemon. Meanwhile, Whiscash is still an effective user of Dragon Dance, which alongside its good bulk and excellent neutral coverage, allows Whiscash to be an effective late-game cleaner or revenge killer. Whiscash is a severely underrated Pokemon in this metagame, both offensively and defensively, and has the potential to excel in both roles given the right support.
Unlike most Water-types, Whiscash has access to Dragon Dance, letting it become a deadly physical sweeper after a boost by combining the offensive capabilities of Lapras with the excellent defensive typing and physical STAB of Seismitoad. With full offensive investment, Whiscash reaches an Attack stat of 383 and a Speed stat of 360 after a boost; although these stats are not amazing, they still allow Whiscash to outspeed and decimate offensive Pokemon effectively enough, as almost nothing in the tier outspeeds it after a boost. Due to Whiscash's good bulk and excellent typing, if the opponent lacks a Grass-type response, it can probably accrue more than one boost, letting it fare much better against defensive walls. Furthermore, if your team can provide it with rain support, Whiscash can be extremely difficult to kill due to Hydration + Rest letting it fully restore itself instantly. While Whiscash does not function as well as a straight-up sweeper due to its mediocre offenses and lack of super-effective coverage, it is at its best as a late-game sweeper, cleaning up beaten up threats and being generally unkillable once the opponent's Grass-types are gone.
Earthquake is the primary STAB move since it hits Fire- and Rock-types harder than Waterfall, whilst Stone Edge provides the infamous EdgeQuake combo that hits almost every Pokemon in the game neutrally. Waterfall is still used as a secondary STAB move as it hits Pokemon with Levitate harder than Stone Edge in most cases, and the flinch chance can be useful in tense situations. Under rain, Waterfall is more powerful than Earthquake and becomes the primary STAB move, but Earthquake remains for its use against bulky Water-types. Stone Edge is the most expendable move in this case, and can be replaced by Rest to provide Whiscash with the instant recovery that makes it so hard to take down through residual damage.

While Whiscash has the potential to sweep teams quickly with an all-out offensive set, it also has the option of taking a slower route to sweeping by using a bulky Dragon Dance set, just like Altaria and Shelgon. Whiscash's excellent defensive typing is often criticized for its 4x weakness to Grass-type attacks, but it provides Whiscash with a plethora of resistances and an immunity to Electric-type attacks as well, both of which it can make use of thanks to its large HP stat and decent defenses. Additionally, Whiscash can make 101 HP Substitutes, which cannot be destroyed in a single hit by Seismic Toss, letting it set up on Pokemon such as Miltank, Lickilicky, and Hypno. Due to its good bulk, Whiscash's Substitutes will often also survive neutral Hidden Powers, uninvested Scalds, and other weak attacks. In addition, phazing moves such as Lickilicky's Dragon Tail and Throh's Circle Throw, in addition to Clear Smog, will not affect Whiscash while it's behind a Substitute, letting Whiscash hit them with two boosted Earthquakes before being forced out, which will either deal heavy damage or KO them outright. By using Substitute tactically against less offensive opponents, Whiscash is able to set up multiple Dragon Dances more easily, and thus has a greater chance of sweeping teams that cannot immediately threaten it. Once opposing Grass-type Pokemon are removed, stall teams will find it much harder to deal with this variant of Whiscash than the standard, as Substitute blocks both Toxic and phazing moves, their next best options at removing it from play.

Whiscash's access to Hydration finally allows it to compete with Seismitoad as a physically bulky Water-type. Whiscash can heal itself of status, such as Toxic, by using Rain Dance, and fully restore itself with Rest, giving it more longevity when rain is up. Whiscash can make the most of its marginally lower Special Attack and the boost that Rain Dance provides to hit opponents hard with Hydro Pump and Earth Power. For reference, Hydro Pump manages to 2HKO Regice under the rain, and thus everything else it hits neutrally in the tier. Since most targets of Water- and Ground-type moves in this tier are physically defensive, Whiscash can make use of its special STABs more effectively than it can its physical options. While this set faces competition from Lapras, access to STAB Earth Power and far better physically defensive typing give Whiscash unique qualities that make it worth considering. However, bear in mind that because this set must use a turn to set up Rain Dance before it can tank effectively, Grass-types should be eliminated before you attempt to set up rain, as they can switch in with little risk. If your team already provides Whiscash with rain support, then Ice Beam can be used over Rain Dance to hit those Grass types hard on the switch-in; Ice Beam also has the added bonus of being able to OHKO Altaria.

A RestTalk set can be used but it's pretty much directly outclassed by Rain Dance + Rest, as you have little reason to use any ability other than Hydration. An all-out special attacking set can be run with Hydro Pump / Earth Power / Ice Beam / Surf and maximum Special Attack investment. However, this set isn't terribly effective against offensive teams as their sweepers will outspeed and wear Whiscash down fairly, and Life Orb recoil stacks up too. Hidden Power can't really hit anything in the tier harder than Whiscash's other options, so it's not worth considering. Substitute can be useful for blocking status and Grass-type attacks, but it drains Whiscash's HP quickly in tandem with Life Orb, and Rain Dance + Hydration is generally a better defense against status. Toxic can also be used to annoy other bulky Water-types.
Checks and Counters
By virtue of its typing, almost any Grass-type can counter Whiscash so long as it can survive a +1 Stone Edge. Torterra completely walls any set that lacks Ice Beam due to its defensive typing, and can promptly OHKO Whiscash with Seed Bomb or any other Grass-type move it carries. Tangela and Exeggutor can also come in on Whiscash easily and set up as it switches. Cacturne switches in comfortably on Water-type attacks, as well as unboosted Earthquakes and Stone Edges, and can proceed to set up Spikes or a Substitute as it forces Whiscash out. Bulky Water-types, such as Alomomola, also deal with well Whiscash since they take little from Whiscash's neutral attacks, and can threaten a burn or KO with repeated neutral Scalds, possibly boosted by Whiscash's rain support. In terms of other offensive checks, Whiscash can be surprisingly difficult to stop if it has rain support, and thus, it's often best to stall out the rain before attempting to go for a direct KO.
