Why Use Weavile?

Weavile is both extremely fast and powerful, with the perfect movepool to make him a highly effective revenge killer or late game sweep. He provides a simultaneous answer to many top tier threats in OU, such as Latias, Salamence, Starmie and Azelf.

Weavile's movepool has brilliant neutral coverage, meaning that not many pokemon can switch in without getting seriously harmed. His usage may have plummeted since Scizor's arrival to OU, but nonetheless, he is still an extremely dangerous threat, and needs to be prepared for.

Movesets:

Physical Attacker:
Weavile @ Life Orb / Choice Band
Ability: Pressure
Jolly nature (+Spe, -SAtk)
EVs: 32 HP | 252 Atk | 184 Spd | 40 SDef

• Pursuit
• Ice Shard
• Low Kick
• Night Slash / Ice Punch

Set Description:

When you combine Weavile's blinding-fast Speed and his smooth 120 Base Attack, along with Pursuit, the result is a formidable revenge killer. Although Weavile is often predictable, a well-timed STAB move can change the course of the game. Having a Pokémon with the ability to stop a Dragon Dance Salamence and Tyranitar sweep unscathed is a great addition to any team; Ice Shard negates Salamence's Speed boosts, while he outspeeds Tyranitar even when it is holding a Choice Scarf. His revenge killing prowess doesn't stop there however; with Pursuit alongside Stealth Rock support, he is capable of handling most of OU's major threats.

Whilst Weavile's play style is very similar to Choice Scarf Tyranitar's, it does have a few differences that both help and hinder it. Both of them reach massive levels of Speed. Tyranitar has to pay for it though; using a Choice Scarf means that it is susceptible to set up from the likes of Salamence, Magnezone, Empoleon and Heatran. On the other hand, Weavile can switch attacks while still outrunning key threats, such as Latias and Starmie. The Stealth Rock weakness is detrimental to Weavile, and he doesn't have the best defenses one could wish, unlike Tyranitar. However, it should be noted that Weavile usually needs few turns to fulfill its role on your strategic plan. It is true the fact that Tyranitar is able to switch-in on attackers and beat them and that Weavile has to rely on the rather undependable Revenge Killing method, but it is also true that once Weavile has done his job, a rather easy task when played well, he won´t be needed anymore on the game, meaning that playing him conservatively isn't a concern to the standard Weavile user.

Note that Pursuit is highly useful against Choice Scarf Flygon locked into Earthquake, as they are almost guaranteed to switch out. The Pursuit will leave Flygon heavily damaged and easy to kill, even from resisted moves. However, this tactic comes with a risk. If Flygon doesn't switch out, you will lose your Weavile to the Earthquake.

Removing Blissey or Cresselia from the battle will ease some Pokémon's ability to sweep. Tyranitar has troubles accomplishing this task because most Blissey will first use Protect to scout for choiced moves, whilst Cresselia can severely cripple Tyranitar with the combination of Thunder Wave and Reflect. Weavile, on the other hand, can use Pursuit on the Protect and then Low Kick on the Wish / Softboiled, and Cresselia can be played around with the combination of Night Slash and Pursuit. In summary, Tyranitar has better bulk while Weavile has better a better offense and Speed and coverage.
As mentioned beforehand, Ice Shard's usefulness can't be depreciated on this metagame where Salamence runs rampant. If you are confident of a Salamence switch, Pursuit will nearly OHKO him after Stealth Rock and Life Orb recoil, meaning that when Pursuit is played correctly, Salamence can be a non-factor by just using one move on the match.

Weavile actually has decent Special Defense and base HP, so he can take a Thunderbolt from Choice Scarf Rotom-A, and then retaliate with the combination of Pursuit and Ice Shard. Low Kick is the preferred option over Brick Break because in OU the only Pokémon that is hit harder by Brick Break than Low Kick is Blissey, whom Weavile shouldn’t have any problem with anyway. Low Kick also OHKOs Heatran, Magnezone (whom Weavile outruns even with a Choice Scarf equipped) and Lucario to name a few. The choice in the last slot is a tough one: with Night Slash Weavile can play mind games with Pursuit against Pokemon weak to the Dark Type, like Rotom-A and Azelf, while Ice Punch will hit neutral things harder like Gyarados and Machamp. The recommended move however is Night Slash, because once your opponent realizes that Weavile lacks a secondary Dark STAB, it will be reluctant to switch-out, messing up the whole point of the strategy.

The EVs seem complex, but they are very specific; 32 HP EVs hit a Life Orb number, which enhances the number of times Weavile can attack, 11 instead of 10. Max Attack is used to ensure the aforementioned key OHKOs. The Speed investment enables him to outpace Choice Scarf Tyranitar, as well as Starmie and anything slower. The remainder was placed into Special Defense, because Weavile will be likely taking Special attacks from the targets of Pursuit, and also makes Weavile a much better switch-in on Blissey.

Weavile´s attributes are often underestimated; that's why, when played well, he can turn the tables in your favor.

Swords Dance:
Weavile @ Life Orb / Expert Belt
Ability: Pressure
Jolly nature (+Spe, -SAtk)
EVs: 252 Atk | 216 Spd | 40 HP

• Swords Dance
• Ice Shard / Punch
• Night Slash
• Low Kick / Brick Break

Set Description:

Weavile's incredible Speed and power enables him to force a lot of switches in today's fast paced Metagame. Taking advantage of this opportunity to set up a Swords Dance makes him a dangerous foe. Even dedicated physical walls will struggle to stand up to the brute force that Swords Dance Weavile exhibits. Very few pokemon can switch into Weavile after a Swords Dance boost without getting heavily maimed, at the least.

The 40 HP EVs allow Weavile to survive an unboosted Flamethrower from offensively inclined lead Azelf. The EVs are taken from Speed, as there is no need for a Weavile to run maximum Speed, due to being the only one of his Speed tier in OU. The rare Sceptile will fall to Ice Shard anyway.

If you wish, or if you have Azelf otherwise covered, you can max out his Speed stat, and surprise the few attackers that would normally aim to outrun 216 Speed Weavile, as well as other Weavile. However, this is often deemed unnecessary, as many simply use priority to dispose of Weavile, thanks to his frangibility. After this, his Attack is maxed out, for optimum power, and also simply because Weavile needs all the power he can get.

Swords Dance and Night Slash are staple on this moveset. Night Slash is Weavile's most powerful option for a Dark typed STAB move, and Swords Dance is the pivotal move of the set, separating it from the "4 attacks" set. Ice Shard is generally recommend over Ice Punch, as it allows Weavile to easily revenge Dragon Dance Salamence or Dragonite locked into Outrage, as well as Choice Scarf Flygon, and it can finish off a weakened Gliscor or Latias, thus making Weavile a highly effective revenge killer for all of these Dragons. However, if Ice Shard's priority isn't needed, and you have all of these threats covered, Ice Punch packs a lot more power, and guarantees the OHKO on Gliscor, and all bar the bulkiest of Latias.

The Choice between Brick Break and Low Kick is a tricky one. Low Kick hits a lot of threats to Weavile for a lot of power (Tyranitar, Heatran, Scizor), and doesn't lose many of the 2HKOs that Brick Break yields, but Brick Break on Weavile is extremely viable because of the Ghosts that fear him. Brick Break allows him to shatter barriers, and completely counteract any efforts made by Dual Screening leads.

A Jolly nature is used more often than Adamant, as it takes Weavile to a wonderful Speed point, allowing him to outrun Scarfed Magnezone and Tyranitar, whereas Adamant Weavile will find himself outrun by the aforementioned threats, and hence unable to revenge kill them.

Pairing Weavile up with a Magnezone is a good idea, as it allows you to remove Scizor from the battlefield, one of the greatest threats to Weavile. Removing as many physical walls as possible is also highly recommended, as it will ease Weavile's sweep. Hippowdon is one of these, despite being a Ground type, as his amazing physical bulk allows him to take even a +2 Ice Punch from Weavile, and simply kill with Earthquake. a bulky Water type such as Swampert or Vaporeon would therefore make another good companion with Weavile, as they can eradicate Hippowdon, and Vaporeon can provide Wish Support, which is something Weavile really appreciates, with his Stealth Rock weakness somewhat limiting his lifespan, not to mention Life Orb sapping his HP yet further. This is why the Expert Belt is also listed as a viable hold item. You retain a boost in power, and it also allows you to bluff a Choice Band, whilst keeping you alive for longer, due to the lack of Life Orb recoil.

However, as the boost only applies when he hits an opponent for Super Effective damage, your hole punching abilities will be slightly hampered because of this. Be cautious with its usage.

Anti Lead:

Weavile @ Focus Sash
Ability: Pressure
Jolly nature (+Spd, -SAtk)
EVs: 252 Atk | 252 Spd | 4 HP

• Fake Out
• Taunt
• Counter
• Ice Punch / Night Slash

Set Description:

Weavile makes an effective anti lead, by being one of the few able to stop Suicide leads, such as Azelf, and sometimes Aerodactyl.

After breaking the opponent's Focus Sash with Fake Out, his incredible base Speed allows him to Taunt almost any other lead before they can Taunt him, or even attempt to setup. As Aerodactyl and Crobat are the only common leads who outrun Weavile, Ice Punch is the higher recommended move, as it hits both of them for Super Effective damage. However, as Counter can be used to bounce back physical moves, Night Slash is just as useable against Azelf, another highly common lead who tends to be more specially based than physical.

Anti lead Weavile belongs on offensive teams where Azelf doesn't fit in well. Drastically different typing brings Weavile a whole set of different resistances that Azelf can't boast. It is recommended that you pair him up with a pokemon who can abuse Stealth Rock, and cover for Weavile's weaknesses, most notably Fighting. Gliscor is a great candidate for this position, as he can capitalize on opponents that Weavile has Taunted, and resists Bug and Fighting moves nicely, not to mention his ability to counter many things that Weavile fears, such as Heracross, Lucario and Scizor.

On this set, both Attack and Speed are simply maxed out, as it's unlikely that Weavile will be taking a Flamethrower from Azelf, if he is used correctly.

If you wish, you can forgo Fake Out for Ice Shard. This would mean that you have a priority which always works. However, you would have to bring your opponent down to their Focus Sash and finish them off with Ice Shard, instead of breaking it with Ice Shard, because it doesn't have the flinching prowess that Fake Out does. It lets Weavile beat Crobat and Aerodactyl leads with certainty however, as Ice Shard will 2HKO them both. Fake Out is recommended against nearly every other lead, however.

Novelty:

Punishment is effective against stat boosting opponents, such as Jirachi and Suicune. It will really start to hurt after a couple of Calm Mind boosts.

Weavile is great at forcing switches, so a SubPunching set is perfectly viable, with Night Slash and Ice Shard as the other moves.

Screech can be used in tandem with pursuit to help soften up bulkier opponents, and even help him to sweep through physical walls such as Hippowdon and Skarmory.

Aerial Ace hits Machamp, Infernape and other fighters much harder than anything else Weavile has in his arsenal. This can come in useful, should they really trouble your team. However, nearly every Fighting type has access to a priority move, the majority of which Weavile is extremely weak to. This means that he may not have the chance to actually use the move.

X-Scissor is another move Weavile has in his movepool, but there isn't really anything that it would hit harder than one of Weavile's STAB or Fighting type moves would, besides Celebi, who would be unlikely to stay in on a Weavile anyway.

Weavile has access to Nasty Plot, but his base Special Attack is just 45, which is extremely underwhelming, even at +2. The only thing to be said about Nasty Plot Weavile is don't use it, unless you plan on using it as a Blissey lure, with Nasty Plot and all physical moves. It really does work!

Counters:

Because Weavile is so physically potent, and has incredible coverage with his commonly used moves, actually countering him is fairly difficult, as it is hard to switch in on a Weavile without the chance of getting seriously harmed in the process. The easiest way to take out Weavile is to punish him with priority, as he is ridiculously frail, especially on the physical side, not to mention being weak to the majority of commonly used priority moves.

True Counters:

--Infernape: Infernape resists both of Weavile's STAB moves, and can survive a Brick Break. Aerial Ace isn't common enough to threaten Infernape, who often has Mach Punch or Vacuum Wave at his disposal to eradicate Weavile anyway.

--Scizor: Scizor's infamous Bullet Punch will scare Weavile away every time. Low Kick will hurt Scizor, though, should he switch in at the wrong time. Bulky variants can easily Roost this damage off after forcing Weavile out, though.

--Forretress: Forretress' extreme physical bulk means that it can take any of Weavile's moves and KO with Gyro Ball easily. Forretress will be unlikely to attempt set up, however, as Weavile are known to carry Taunt. Nevertheless, Forretress will beat Weavile every time.

--Skarmory: Skarmory shares Forretress' amazing bulk, meaning he can tank Weavile's hits fairly well. His neutrality to Ice Punch makes it harder for him to switch in, but he can still dispose of Weavile fairly easily with a simple Drill Peck, which will 2HKO at the worst. Skarmory can also phaze Weavile out, should he attempt to setup a Swords Dance.

--Hariyama: With Thick Fat, Hariyama resists Weavile's Ice moves as well as Dark, meaning he can switch in fairly easily. Low Kick hits him for a painful 120 base power, but his impressive bulk prevents him from being OHKOd by even a +2 Low Kick, thus making him a full counter to Weavile, as he can simply throw a Force Palm and end Weavile.

--Hitmontop: Hitmontop has access to several different forms of priority, meaning Weavile will be forced to use Ice Shard by means of attacking. Neither Ice Shard or the 60 base power Low Kick will deal enough damage to scare even Technician Hitmontop (who is the least physically bulky), whilst Hitmontop can retaliate with Mach Punch to eliminate Weavile.

--Metagross: Metagross almost always has Bullet Punch to dispatch Weavile, and his amazing Defense lets him take a +0 Night Slash or Low Kick well, despite his heavy weight. The rare Metagross that doesn't carry Bullet Punch will come out of the encounter quite heavily damaged, but will still beat Weavile with Meteor Mash.

Checks:

--Lucario: Lucario's resistance to both of Weavile's STABs, not to mention a rare 4x resistance to Pursuit and Night Slash, gives him plenty of opportunities to switch in on a Choiced Pursuit or similar, and set up a Swords Dance as Weavile is inevitably forced out. However, Lucario can't switch into a Fighting move, as they will severely cripple Lucario's sweeping capabilities, and that's if he survives the hit. Note that Lucario can also revenge kill Weavile easily with Extremespeed, if necessary.

--Gyarados: Gyarados has Intimidate to soften Weavile's blows, but a Weakness to Stealth Rock and a mediocre base 81 Speed means that Gyarados will need to take 2 hits before he has a chance to attack. Heavily defensive Gyarados can accomplish this, and then seek vengeance with Waterfall, but even defensive Gyarados will fall to a +1 Swords Dance Weavile, meaning that Gyarados can't counter.

--Heatran: Heatran's heavy weight means that Low Kick will be fatal to him, should he switch into it. However, Choice Scarf Heatran outruns, and can throw a Fire Blast at Weavile and end the problem once and for all.

--Heracross: Choice Scarf Heracross outruns Weavile, and can potentially scare him off with the threat of a Megahorn or Close Combat. However, Choice Scarf Heracross doesn't take physical hits very well, and Heracross only needs to switch into Stealth Rock twice for a +2 Ice Shard to threaten a KO.

--Hippowdon: Hippowdon gets a mention for being able to survive a +2 Ice Shard, as well as being able to beat Anti Lead Weavile, thanks to the sandstorm he summons. Although, being a Hippowdon, he is easily outrun, and he cannot survive a +2 Ice Punch, even with his incredible physical bulk.

--Bronzong: Bronzong can destroy Weavile with a Gyro Ball, but can't switch in too well, as Weavile's Night Slashes will seriously harm it. If Bronzong beats Weavile, it will be damaged to the point of death fodder, with a +2 Night Slash 76% on average, meaning that Bronzong will be too damaged to attempt setup. Note that Weavile can also Taunt Bronzong as well.

--Machamp: Machamp can easily destroy Weavile with a Dynamicpunch, but his physical bulk simply isn't enough to take Weavile's Ice Punches or Low Kicks very well. Even the more defensive Machamps will be severely maimed by a +2 Low Kick.

Weavile is a counter to:

Weavile's frailty means that he actually counters very few things, as there aren't many attacks he can switch into well. The pokemon with moves he can switch into generally have a coverage move that would damage him heavily, and hence remove his chances of a safe switch in. However, whilst Weavile counters few, he serves as a check to many.

Weavile is a check to:

--Latias: Weavile's ability to keep Latias in check is partly what is keeping him in OU. Latias fears Weavile switches, as literally any of his STAB moves, be it Pursuit, Ice Shard or Night Slash, will severely maim Latias at the very least

--Flygon: Weavile can easily revenge kill Flygon with an Ice Shard, should he lock himself into Outrage. However, Weavile can in no way switch into Flygon, as almost every move commonly used by Flygon can kill Weavile with little to no trouble.

--Salamence: Similarly to Flygon, Salamence is easily revenged by Weavile's Ice moves. However, also like Flygon, Weavile can't switch into any of Salamence's moves, aside from Dragon Dance. Scouting is recommended, so to distinguish which Salamence variant you are fighting, whether it is Dragon Dance, mixed or choice.

--Tyranitar: Weavile's amazing Speed lets him outrun even Choice Scarf or +1 Dragon Dance Tyranitar, and literally pulverize with Low Kick, which hits the dinosaur for a brutal 120 base power. Sadly, though, Tyranitar poses too great a physical threat for Weavile to switch in easily. Even a resisted Crunch will turn Weavile into death fodder, whilst any other common move will simply massacre the poor weasel.

--Starmie: Weavile outruns Life Orb Starmie easily, and will get the kill almost without fail, as only the bulkiest of Starmie can survive a Pursuit, and that's if they stay in. However, Choice Scarf Starmie will get 2 easy hits on Weavile, which will kill, thanks to Weavile's frailty.

--Gengar: Gengar is perhaps Weavile's favorite revenge killing prey, being easily able to switch into a Choiced Shadow Ball, and Pursuit trap Gengar to death. But switching in without scouting is discouraged, as Gengar often carries Focus Blast or Hidden Power Fire, both of which will severely damage Weavile. Choice Band Weavile can also be used as setup fodder by a Gengar and Lucario combo, too. Beware of this. The same applies to any other Ghost or Psychic type that Weavile can kill with Pursuit.

--Rotom-A: Rotom's average base 86 Speed means that Weavile can outrun even some Choice Scarf variants and Pursuit trap them. However, nearly every Rotom appliance carries a status move in Will-o-Wisp or Thunder Wave, both of which will cripple Weavile to the point of death fodder. It is therefore recommended to switch in at an appropriate time rather than just arbitrarily, as that could seriously backfire.

--Dusknoir: Dusknoir is in the same boat as Rotom-A, carrying status moves often enough to discourage Weavile from readily switching in, but unable to fend him off, should he manage to switch in safely. Dusknoir can also carry Fire Punch or Brick Break to hurt Weavile too, however.

--Celebi: If Weavile can avoid a Thunder Wave, he can scare Celebi off almost every time, as either STAB will inflict serious damage to the vegetable. Celebi can use Hidden Power Fire, however, to make sure that Weavile goes down with her.

--Breloom: Once Breloom's put another opponent to Sleep via Spore, Weavile can easily revenge kill with Ice Punch/Shard, providing Breloom hasn't set up a Substitute.

--Gliscor: Weavile's Ice Punch will decimate non Yache variants of Gliscor, but he can survive an Ice Shard, and at the very least bring Weavile into KO range with Earthquake.

--Mamoswine: Weavile can't switch into Mamoswine's Earthquakes, Stone Edges or Superpowers, but can destroy the heavy elephant with Low Kick, which is a guaranteed KO against all bar the bulkiest of them.

--Cresselia: Cresselia can't really damage Weavile outside of the uncommon Hidden Power Fighting, but Weavile will have trouble stopping her from setting up at least one defensive Screen, and then healing a team mate with Lunar Dance. However, Weavile can use Brick Break to remove those Screens, should he need to. Cresselia can also cripple Weavile via the use of Thunder Wave, too. Weavile should be wary of this, as Cresselia carries it often.

--Magnezone: Magnezone's paltry base 60 Speed means that Weavile can outrun even Choice Scarf variants, and punish them with Low Kick. Magnezone's heavy weight means that the kick will often be fatal. However, Weavile can in no way switch into Magnezone safely, as literally every common move that Magnezone carries will hurt Weavile, whether it's Hidden Power Fire, Flash Cannon or just a simple Thunderbolt.

Team Options:

In order to set up a Weavile sweep, literally any form of priority must be removed from battle, and physical tanks must be softened to the point of sweeping through, at the very least. It is therefore recommended that you pair Weavile up with a Magnezone, as they are great at eradicating many of the aforementioned threats (Lucario, Scizor, Skarmory and Forretress are all fine examples).

Weavile also dislikes bulky Waters, all of whom can stop his sweep fairly easily. packing a lure or outright counter would be a good idea to rectify this problem. Choice Band Infernape helps break through most of them, as does Celebi, who can also throw Thunder Wave around to ease Weavile's sweep.

If Weavile is supporting a sweep, it should be for a powerful pokemon who appreciates fast opponents such as Starmie, Latias and Gengar being removed beforehand. Salamence is a perfect example of one of these pokemon, as well as Mixed Infernape.

Weavile also pairs up nicely with Lucario on an offensive team. What counters Lucario can be worn down by Weavile, and vice versa.

Conclusion:

Weavile's usage may have plummeted since the days of Diamond and Pearl, thanks to Scizor receiving Bullet Punch, but with push comes pull. Latias' demoting to OU gave Weavile a new lease of life. By being one of her best checks, Weavile has proved that given the opportunity, he can still shine.

[DrakoRising]

Weavile is one of the best pursuiters. His amazing speed and attack guarantee a kill, switch out or not. Weavile also has access to quite a nice movepool with fighting, dark, ice, and flying.

[throwknife]

Note that he is the fastest user of a STAB pursuit.

[legendary_07]

Instead of making two separate sets for CB and "LO 4 Attacks", I think you should make a single set with Life Orb / Choice Band as the item options.

Weavile @ Life Orb / Choice Band
Jolly
40 HP / 216 Spe / 252 Atk
Pressure

This is because, from personal experience i know that CB Weavile just doesn´t works as well as he used to do on DP--one mispredict means 50% of your health for nothing due to Stealth Rock (assuming you switch-in on a non-damaging move.)
Actually, I think I want to write that set, the "LO 4 Attacks", if you allow me to do so, of course.

[KiwiDean]

Hmm, fair point.

Sure, you can write the set if you wanna. Means less work for me.

[KiwiDean]

Posting to say that I think this analysis is finished, once Legend posts his part.

Criticism would be much appreciated if poss. Thanks.

[legendary_07]

I kinda forgot about this, sorry! I am reworking and made some changes like Nature, EV Spread and held Item. It will be finished in the next few days (hours?) Confirming activity though.

[KiwiDean]

No worries, Legend. Take your time, lol.

[legendary_07]

Pursuit

Weavile @ Life Orb
Pressure
32 HP / 252 Atk / 184 Spe / 40 SpD
Jolly
Pursuit
Ice Shard
Low Kick
Night Slash / Ice Punch

When you combine Weavile´s blinding-fast Speed and his smooth 125 Base Attack, along with Pursuit, the result is a formidable revenge killer. Although Weavile is often predictable, a well-timed STAB move can change the course of nature of the game. Having a Pokémon with the ability to stop a Dragon Dance Salamence and Tyranitar sweep unscratched is a great addition to any team; Ice Shard negates Salamence´s Speed boosts while he outs speeds Tyranitar even when it is holding a Choice Scarf. His revenge killing prowess doesn´t stop there however, with Pursuit along Stealth Rock support he is capable of handling most of OU treats.
While Weavile's play style is very similar to Choice Scarf Tyranitar's, it does have a few differences that both help and hinder it.
Both of them reach massive levels of Speed. Tyranitar has to pay for it though; using a Choice Scarf means that it is susceptible to set up from the likes of Salamence, Magnezone, Empoleon and Heatran. On the other hand, Weavile can switch attacks while still out speeding key Pokémon like Latias and Starmie. The Stealth Rock weakness is detrimental to Weavile, and he doesn´t have the best defenses one could wish, unlike Tyranitar; it should be noted though, that Weavile usually needs few turns to fulfill its role on your strategic plan. It is true the fact that Tyranitar is able to switch-in on attackers and beat them and that Weavile has to rely on the rather undependable Revenge Killing method, but it is also true that once Weavile has done his job, a rather easy task when played well, he won´t be needed anymore on the game, meaning that playing him conservatively isn´t a concern to the standard Weavile user.
Removing Blissey or Cresselia few from the game will enlighten some Pokémon´s capability to sweep. Tyranitar has troubles doing this task because most Blissey use Protect to scout for choiced moves, while Cresselia can cripple permanently Tyranitar with the combination of Thunderwave and Reflect, while Weavile can use Pursuit on the Protect and use Low Kick on the Wish / Softboiled, while Cresselia can be played around with the combination of Night Slash and Pursuit. In summary, Tyranitar has better bulk while Weavile has better a better offense and Speed and coverage.
As mentioned beforehand, Ice Shard´s usefulness can´t be depreciated on this metagame where Salamence runs rampant. If you are confident of a Salamence switch, Pursuit will nearly OHKO him after Stealth Rock and Life Orb recoil, meaning that when Pursuit is played correctly, Salamence can be a non-factor by just using one move on the match.
Weavile has actually decent Special Defense and base HP, so he can take a Thunderbolt from Choice Scarf Rotom-A while beating him with the combination of Pursuit and Ice Shard alongside Stealth Rock. Low Kick is the preferred option over Brick Break because on OU the only Pokémon that is hit harder by Brick Break than Low Kick is Blissey, whom Weavile shouldn’t have any problem with anyway. Low Kick also OHKOs Heatran, Magnezone (whom Weavile outspeed even with a Choice Scarf equipped) and Lucario to name a few. The choice in the last slot is a tough one: with Night Slash Weavile can play mind games with Pursuit against Pokemon weak to the Dark Type like Rotom-A and Azelf, while Ice Punch will hit neutral things harder like Gyarados and Machamp. The recommended move however, is Night Slash, because once your opponent realizes that Weavile lacks a secondary Dark STAB, it will be reluctant to switch-out, messing up the whole point of the strategy.
The Evs seem complex, but they are very specific; 32 HP Evs is a pretty good Life Number, as it enhances the number of times Weavile can attack, 11 instead of 10. Max Attack is used to ensure the aforementioned key OHKOs. The Speed investment is outpace Choice Scarf Tyranitar, and along him, Starmie and anything slower. The rest was split on its Special Defense because Weavile will be likely going to handling Special Attacks from the targets of Pursuit, and also makes Weavile a much better switch-in on Blissey.
Weavile´s attributes are often underestimated; smart people can use this on their favor.

Second Edit** Ultima did a pretty cool thing on the format of the text with my last RMT, it would be cool
if that could be applied here (if you even get what i mean!)

[KiwiDean]

Bumping bcuz updated format. Just needs a proofread to be site ready.
