<p>Probopass is one of the best utilizers of the FEAR strategy. Probopass possesses unique traits over other FEAR users, such as Aron, such as the ability to in that it can switch in even if Stealth Rock is up and retain Sturdy, which enables it to pull off its execute its strategy with greater effect. When Probopass gets in safely, it is a terror to stop; however, although there are certain Pokemon in OU that can still shut it down provided they get the a chance. Steel-types, moves such as Leech Seed or Bullet Seed, and burn status, and hail all threaten to break Study, and hail can be very bothersome. Quick hazards from the few many Custap leads, such as Skarmory, and Forretress, and the rarely seen Crustle, [if it's rarely seen, why bother mentioning it?] are also a pain to Probopass, as multiple enough hazards down will break Study Sturdy and nullifying nullify its strategy. In addition, Probopass requires a large amount of team support to be used effectively, a factor that makes it overlooked by many batters battlers in favor of using something more reliable. Despite this these flaws, however, if used carefully and given the proper support, Probopass can be a very useful member on teams if used carefully and given the proper support.</p>
Sentence structure was an issue in most of this paragraph with a couple of spelling errors here and there, but overall it's written just how any overview should be written.

[SET COMMENTS]
<p>This is the only reason Probopass should be used in OU. The set's concept is simple: Sturdy keeps Probopass alive so it can use Pain Split, which heals it and drain drains the opponent's health. However, Pain Split should be used sparingly when the opponent is low on health, as the opponent needs they will need 26 HP left to keep Probopass alive. Protect recovers the damage taken from Stealth Rock or a layer of Spikes, scouts for dangerous attacks, and stacks up sandstorm or poison damage. Toxic hinders those that try to utilize healing moves, and Magic Coat bounces back moves such as Taunt and Spore. Alternatively, Taunt can be used to stop prevent Probopass from becoming setup bait. Aron is Probopass's main competition in employing the FEAR strategy due to its speed and reliability, but, as it works fast and well. Probopass can switch into hazards, and its has access to Magic Coat and Taunt are its advantages over Aron which Aron dreams of boasting.</p>
When you say Aron is Probopass's competition because "it works fast and well," I had no idea what you meant by this. What exactly makes Aron perform this better than Probopass? I simply just removed it and added "its speed and reliability," which still doesn't make me satisfied, but it really had no meaning. Up to you if you want to fix that or remove it altogether.
[ADDITIONAL COMMENTS]
<p>Taunt can be used, but the priority of Magic Coat gives sleep users trouble. [You already said this above, no need to reiterate.] Berry Juice can be used to ease prediction and give Probopass a free turn to do something silly potentially useful like setting up Stealth Rock, but the ability to switch into a layer of hazards is sorely missed highly preferred.</p>
<p>Probopass needs the proper support to accomplish what it's meant to do. Sandstorm is a must, so Tyranitar or Hippowdon are good partners. Toxic Spikes users, such as Forretress and Tentacruel, help provide residual damage and possibly allow Probopass to run another move other than Toxic. Furthermore, they can provide Rapid Spin support, which isn't required but definitely recommended, as too many layers of Spikes pushes Probopass over the edge. Probopass It can switch in to two layers of hazards by using Protect twice in a row, but this strategy only works 50% of the time and thus becomes unappealing and risky. Probopass also cannot finish Steel-types or grounded Rock-types or Ground-types [Why can't Probopass finish off Steel-, Rock-, or Ground-types? Mention this. Also, mention partners that can remedy this issue so Probopass can do its job.]. When using this set, Probopass, one mistake will render him Probopass useless, so when in doubt, scout with Protect.</p>
You're missing some important pieces of information. When you say that Steel-, Rock-, and Ground-types completely block Probopass from doing its job, you need to mention what Pokemon or the like can be used to prevent this from happening. The OU metagame is flooded with the aforementioned types, so this has to be addressed if you want this set to succeed.
[Other Options]
<p>Probopass has very few other options as FEAR is its only set that isn't severely outclassed. It could function as a tank, but its atrocious typing renders it weak to the omnipresent Earthquake and Close Combat, not even mentioning the myriad of better options Pokemon to choose from. Probopass can also function as a trapper, but is almost always outclassed by Magnezone unless you want to use Probopass's take advantage of its access to Magic Coat or Taunt.</p>
[Checks and Counters]
<p>Probopass cannot finish Steel-types as he it has no way to deal residual damage for the kill. Grounded Rock-types and Ground-types also pose problems, but need to be wary of ]can be dealt with, but only via Toxic Spikes or Toxic. Probopass also fears Pokemon with status moves, multi-hit moves, negative priority moves, Leech Seed, Substitute, and abilities that bypass Sturdy like Mold Breaker. Any of these will render Probopass's niche playstyle Sturdy worthless, making Probopass good as gone. Anything with Scald should burn Probopass. [You don't need to say this since you said status moves above.] Changing the sandstorm weather negates finishing damage, but Probopass can still whittle away at your Pokemon's HP. Flinches and hail are also very troublesome. Most teams already have a check to Probopass, such as Jirachi by flinching, Kyurem-B because of Teravolt, Gengar with Substitute, Ferrothorn with Leech Seed, or Breloom with Bullet Seed, so all you'll need to do is keep it alive. [Redundant information in my opinion. You already explained multi-hit moves, Substitute, flinching, etc as ways to beat Probopass, the reader can figure out where to go from there.]</p>
