[Overview]
<p>Walrein's niche in UU lies in its decent bulk and access to great passive recovery in Hhail via Ice Body. WiThanks to the support given from Snow Warning support, Walrein restores 1/8th of its health every turn and can use Protect to gain 1/4th of its health before the opposing Pokemon can even land a hit. ItWalrein's good bulk allows it to force out weak attackers and set up a Substitute. Once it is behind a Substitute, it can use Protect to while easily recovering health wasted by Sube HP lostitute so that Walrein can rack up Hail damage. Its Special Attack is decent andenough to make use of, and its a STAB Blizzard can deal decea fair amount of damage. However, its Water / Ice typing leaves it weak tovulnerable two common UU attack types, Electric- and Fighting-type attacks, (AC) both of which are common in UU. It also has a weakness to Stealth Rock and alll forms of entry hazards, (AC) specifically Stealth Rock. Even so, Walrein canhas the potential to pull its weight on Hhail teams due to its good bulk and great passive recovery.</p>(Alot of re-wording in there; the main issue is that you already go in-depth of Substitute and Protect in the set comments where they belong, and the Overview is the breath, not depth, so you don't need to repeat it throughout the entire thing. Also, no 'th' for fractions.)

[SET COMMENTS]
<p>This set aims to take advantage of Walrein's good defenses and decent Special Attack to become a bulky threat. Walreihen utilizes Protect and Substitute are combined with passive recovery from Leftovers and Ice Body to, (AC) Walrein can almost always take no net damage while the opponents loses health to hail damage. The process workHere is how Walrein's rolike plays outhis: Walreiit can forces as switch withbecause of its good bulk and powerful STAB Blizzard. It then uses Substitute as the opponent switches and recovers a total of 12.5% of it's health due to Leftovers and Ice Body. Then, (AC) Walrein uses Protect, gaining another 12.5% health and fully recovering the 25% health used to construct a Substitue. The next turn wIf then your opponent succeds in breaksing the Substitute the following turn, Walrein just constructs a new one, and (RC) while waitsing for the passive damage from hail to build. Blizzard deals heavy damage to many Pokemon immune to Toxic Spikes, includingsuch as Crobat, Nidoqueen, Nidoking, Roserade, and Zapdos. Roar allows Walrein to phaze set up attackers and deal more passive damage in the form of entry hazards, while Toxic eases reliance on Toxic Spikes support by allowing Walrein to poison opponents itself.</p>(Remember, unless you are specifically talking about the move Hail, hail (as a weather) shouldn't be capitalized!)
[ADDITIONAL COMMENTS]
<p>The EV spread gives Walrein enough Speed to outspeed base 85 Speed Pokemon that invest 8 Speed EVs, (AC) such as Gligar and Suicune. The HP EVs allow Walrein's Substitutes to always take a Night Shade or Seismic Toss while making sure that the Substitute/ and Protect strategycombination always fully recovers allits HP. The rest is invested in Defense as Water-types aren't often hit for super effective damage by physical attacks. However, the Defense EVs can be invested in Special Defense instead or splitevenly divided, (AC) depending on what threats the team needs to cover. Abomasnow is a vital teammate, (AC) as Hhail is crucial to this set's setuccess. Walrein enjoys Toxic Spikes support as; its strategy involves staking passive damage. Nidoqueen can tank Fighting- and Electric-type attacks that scare Walrein, while Roserade can tank Electric- and Grass-type attacks. As Walrein is weak to all forms of entry hazards, it appreciates the help of a Rapid Spinn user. Blastoise is the best Rapid Spinn user in UU, but it shares two weaknesses with Walrein. Claydol, while an inferior Rapid Spinn user, can tank Fighting- and Electric-type attacks.</p>(Rapid Spinner isn't a word. It's either Rapid Spin user or spinner.)
[Other Options]
<p>Choice Specs takes advantage of Walrein's decent Special Attack, but it is outclassed by Glaceon. Thick Fat can be used to give Walrein a resistance to Fire-type attacks, but Walrein cannot take advantage of all the passive recovery. Walrein has other interesting support moves such as Encore or Yawn, but it has a hard time fitting them into any sets.</p>
[Checks and Counters]
<p>Cinccinno and Rhyperior can use Rock Blast to break Walrein's Substitute and damage it, but both take heavy damage from Blizzard. Bisharp holding with Leftovers can set up on Walrein while avoiding poison, negating hail damage, and resisting Blizzard. Cobalion can also do this while threatening a super effective Close Combat, but it must beware of the Special Defense drops, as Blizzard can then weaken it. (Idk, the sentence alone 'beware the SpD drop' doesn't really tell me why I should fear it; it gets a drop in Defense too, right? So I just added on to it using interpretation.)No Steel-type directly fears Walrein, (AC) ; (semicolon) however;, (AC) they can potentially be phazed by Roar and stalled by the combination of Walrein's great bulk, Protect and Substitute, and hail damage.(Same thing here; besides the weird sentence structure, I added on for more interpretation.) Bulky Shed Skin Scrafty can set up Bulk Ups while, healing status conditions, and hits Walrein for super effective damage with its Fighting-type STAB. HEntry hazards make Walrein unable to take powerful attacks such as Darmanitan's Flare Blitz or Flygon's Outrage. Defensive teams have an easier time against Walrein. Hail damage and Toxic doesn't scare Umbreon, (AC) as it can heal status and HP with Heal Bell and health with Wish, respectively. ResttTalk Snorlax, while rare, takes little from Blizzard and can phaze with Whirlwind, but Walrein canif predict this and phaze withed correctly, Walrein can use Roar before Snorlax.</p>
