[Overview]
<p>(remove space)Walrein is a powerful staller that has proven its worth in RU. It has excellent bulk with 110 / 90 / 90 defenses, and has a powerful ability in the form of Ice Body. Walrein has a deadly tactic involving the use of Ice Body combined with and Leftovers allow Walrein to recover the HP lost from using Substitute in a span of 2 turns. However, Walrein faces some defensive faults;(semi colon) it wields a crippling typing defensively, with 4 weaknesses and only 2 resistances,(comma) it is weak to Stealth Rock, and contains a limited movepool means that Walrein is only good for allows it with one thing use. Walrein also requires support such as rapid spinners for from Rapid Spin due to its vulnerability to Stealth Rock and Toxic Spikes. Despite its numerous flaws, Walrein can,(remove comma) without a doubt,(remove comma) become a deadly staller in the right hands.</p>

move 1: Protect
move 2: Substitute
move 3: Blizzard / Surf
move 4: Super Fang / Toxic / Roar
item: Leftovers
ability: Ice Body
nature: Bold
EVs: 232 HP / 252 Def / 24 SpD
[SET COMMENTS]
<p>The EVs are incredibly important here. 232 HP EVs give Walrein a healthy 419 HP, the 252 Defense EVs with a Bold nature give Walrein maximum Defense, and the 24 Special Defense EVs give some nice special bulk. 419 HP is very important,(comma) as in two turns, with Ice Body and Leftovers,(remove comma) Walrein can recover the HP lost from Substitute,(remove comma) as mentioned earlier. This allows Walrein to continuously spam Substitute and Protect, but only has 32 turns of PP in total. For this set to function at all, you need Hail support,(comma) making Snover a neccessity is invaluable due to Snow Warning. If you use Toxic, set up Toxic on a foe and just keep using Substitute and Protect to wait out enough Toxic and hail damage, and once your foe is in KO range, use either Blizzard or Surf to finish them off. Walrein's Special Attack works in it's favor, because a decent base stat of 95 allows an effective use of STAB. Blizzard is a superior choice due to it's higher power and wider coverage, although Surf can hit Steels that are immune to Toxic, and has higher PP. Super Fang demands a similar concept:(colon) Set up Substitute and Protect, and keep using Super Fang until your foe is in KO range. Roar, the final slashed move, is much better when used in conjunction with entry hazards such as Toxic Spikes support. Toxic Spikes would be a good choice. Roar can also be used to help set up, because set-uppers will ruin your fun with Encore / Taunt.</p>
[ADDITIONAL COMMENTS]
<p>Well, To make a long story short, Walrein needs a healthy amount of support to be successful. If you use Roar or Super Fang, then Toxic Spikes are an excellent choice to cripple the opponent's team. is your best entry hazard option. Roselia makes a great partner is Roselia, not only for can it provide Toxic Spikes, but it can switch into Electric and Grass attacks that Walrein doesn't like. Rapid Spin support is also helpful; Claydol is an excellent Rapid Spinner as it shares great defensive synergy with Walrein, and has access to Stealth Rock of its own. Cryogonal can be partnered with Walrein as it can take advantage of the is nice because it likes hail, being an Ice-type, and it also has access to Rapid Spin and Recover. Another good ally is Dugtrio is a good partner,(remove comma) as it can deal with send those annoying Flying-, Steel-, and Poison-types and send them back from where to where they came, as well as provide Stealth Rock support.</p>
[Other Options]
<p>Sadly, Walrein really doesn't have many other options, due to its very limited movepool. You could run a RestTalk set to remedy Walrein's lack of recovery as a recovery move, or use Yawn to force switches or inflict sleep status, but other than the options already mentioned, Walrein is a one trick pony. as it can help by adding some breathing room to set up.</p>
[Checks and counters]
<p>Any Pokemon that is immune to Toxic and not weak to Ice or Water is an ideal counter. That being said, Muk can provide a Toxic immunity and neutrality to Walrein's STAB moves. Aggron is a shaky check, as it has super effective STAB, resists Ice, and is immune to Toxic, but is weak to Walrein's other STAB, Water. There are many other RU Steels that can avoid Toxic, one of these is Ferroseed, as it also contains has access to a super effective STAB. Most bulky Waters give Walrein a hard time, too. Lanturn resists both of Walrein's STAB moves, and has a super effective STAB to use against it. Also, phazers keep Walrein from setting up. Hariyama also makes a good counter with super effective STAB,(comma) and Guts can abuse Toxic and beat down Walrein. Another ideal counter is Drapion,(space)as it can switch into Toxic Spikes, is immune to Toxic, and has decent Special Defense, and it can just Whirlwind Walrein out. Special defensively inclined Pokemon such as Clefable can easily withstand a Blizzard or Surf. Pokemon with Taunt force Walrein to switch out and prevent it from setting up. Encore not only prevents you from setting up like Taunt, but lets an opponent set up. Being a common counter, status destroys you;(semi colon) burn and poison wither away your HP, while paralysis takes away the little Speed you actually have. Toxic Spikes, (status) pretty much forces you to refrain from switching Walrein in, because you would get poisoned, which slowly drains your health and prevents the Leftovers+Ice Body combination from working. used to ignore Substitute damage.</p>
[Dream World]
<p>Walrein got virtually nothing useful from the dream world. Its Dream World ability is Oblivious,(comma) which This prevents attraction;(semi colon) which is scarcely, if you'd be lucky if this was ever used at all in any tier. It is totally outclassed by Ice Body. Oblivious is never, in any case, viable. Don't use it.</p>
