[Overview] 
<p> Walrein can function without hail support, but it must run an entirely different set. Walrein's typing and Thick FatThough its typing gives it weaknesses to Stealth Rock and Fighting-type attacks and, Thick Fat grants Walrein resistances to both Ice- and Fire-type attacks, making it a solid special wall. Walrein's bulk is impressive; with 110 / 90 / 90 defenses, it can take hits and fire back withresisted hits with ease and fire attacks back off a base 95 Special Attack stat.</p>

[SET COMMENTS]
<p>Walrein iDespite the fall in popularity of hail teams, Walrein is nonetheless amazing because it can switch into any Choice Specs-boosted Ice-, Fire- or Water-type attack and be fine. Because of Thick Fat, Walrein has essentially an octuple resistance to Ice-type attacks, making it a great choice to counter hail teams as Ice-types cannot be frozen and are not damaged by hail. Encore is a great supporting move, and it functions well on WalreinEncore is a great supporting move, and Walrein makes excellent use of it. Encoring the opponent into a stat -boosting move can give you time to switch out andanother teammate the opportunity to set up, changing the momentum of the battle; t. Thus, Encore forces the opponent to use an non -boosted attack or let you prepare a sweep with aone of Walrein's teammates set up. Usually, it forces a switch, allowing you to Toxic another opposing Pokemon. Toxic is, being essential for stalling so it, is necessary for a wall such as Walrein. Depending on what coverage is needed for the team, either Surf or Ice Beam can be used. Surf hits Fire-types that Walrein can easily switch into, and also hits Rock- and Ground-types / Ground Pokemon that can threaten itWalrein with super effective Rock-type attacks. Ice Beam hitdemolishes Flying-types hard, namely Alataria and Swellow, but be careful around them because unless you can predict ayou have to catch the latter on the switch in,as Swellow can KO you with Facade if you are low enough on healthoutspeeds and can KO a weakened Walrein with Facade. Protect racks up Toxic damage whereas Roar can be used in conjunction with entry hazards to phaze and deal a little damage.</p>
[ADDITIONAL COMMENTS]
<p>Walrein works best as a special wall because its resistances are commonly seen as special attacks, but it can run a physically defensive set if necessary. The EVs for this set maximize it's special bulk. Something Walrein has over Slowking is its neutrality to Bug-, Ghost- and Dark-type moves, so the special defensive spread gives Walrein its niche. Walrein likes having supporting teamm</p>
<p>There are several forms of support Walrein appreciates. Using a spinner to rid the field of Stealth Rock is very helpful, but with the few choices available, it mayight be hard to consistently remove hazards. Since it is so hard for Walrein to to tolerateAs Walrein is so weak to hazards, something to remove the opponent's Ghost-type spin blocker could be useful if you do decide to haverun a Rapid Spin user. Anything<give examples of both the previous> Pokemon that resists Fighting-(space)and Rock-type attacks makes a good teammate, such as Exeggutor, whos; Exeggutor for instance can also take Grass-type attacks aimed at Walrein, andwhile Throh, who can tank Fighting-type hits as well, as both types are powerful offensively and are super effective against Walrein.</p>
[Other Options]
<p>Walrein has some other unique options that maycan be viable. Super Fang together with Brine allows Walrein to hit a little harder than usual, but takes up two move slots. Although Super Fang can be used alone, Walrein has enough Special Attack to usemake use of its STAB moves while providing coverage for the team. A physical Curse set is usable and probably one of the better other options Walrein has. If you really need Walrein to function on it's own, Icy Rock can be used with Hail and Ice Body, but eight turns of hail really isn't enough to work with, and even with other stalling support, Ice Body isn't that effective.</p>
[Checks &and Counters]
<p>It can sometimes be hard for Walrein to be effective sometimes due to the widespread use of Stealth Rock, and the powers well as the power and popularity of Fighting -types. If you can get a powerful Fighting-type behind a Substitute before Walrein can Encore you, it should force it to switch out with, such as <what fighting-type commonly uses substitute?> behind a Substitute without being Encored, Walrein will be forced by the threat of Close Combat from powerful Pokemon, such as Sawkto switch out. Faster Fighting-types, such as Sawk, can also threaten Walrein with Close Combat. Poison-types are immune to Toxic and can Toxic Walrein in return, hampering its walling capabilities. As mentioned before, Walrein is easily worn down with Stealth Rock, so if you can continue to force it to switch, Walrein will be much less effective. Finally, Taunt from Pokemon such as <give examples> ruins many of the defensive sets, and usually forcinges Walrein to switch so you canout, giving your Pokemon time to set up a Substitute or use a boosting move .</p>

<p>Oblivious is useless in competitive battling as Attract is nothardly ever used and few viable Pokemon have Cute Charm.</p>
