This is a WIP
[Overview]
After residing in Uber for the DPP era, Mew finds itself in the odd position of being demoted two tiers to the UU tier. While Mew still has its classic movepool that features every TM and move tutor move in the game, it cannot make up for its bland Psychic typing and decent, but not outstanding, stat distribution. However, in UU, Mew is one of the strongest Pokemon in the tier as it can take on almost every role and position. A plethora of boosting moves, such as, Nasty Plot, Swords Dance, Calm Mind, and Bulk Up turn Mew into a powerful sweeper. In conjunction with Baton Pass, Mew can just as easily set up a devastating sweep for others on your team. Mew can run an equally devastating support set that can act as a stallbreaker while continuously walling dangerous and shutting them down with Will-O-Wisp. While Mew may not have the power of the tiers strongest sweepers or the bulk of the tiers sturdiest walls, it can more than make up for it with its astounding versatility that makes Mew a great pick on any team.

[SET COMMENTS]
Hampered by limited distribution and unsuitable candidates, Nasty Plot is a move little used in the UU metagame. That isn't to say that it is in any way bad, Nasty Plot is a powerful boosting move that instantly doubles the Special Attack stat of the user. For a Pokemon that has as wide a movepool as Mew, this extra power can be devastating. After a boost or two, Mew's decent base 100 Special Attack stat is skyrocketed to explosive levels. Psyshock is Mew's way to laugh at special walls, being able to hit them on their weaker Defense stat, however, the stronger Psychic can be used if you know your team can easily clear out special walls for Mew to sweep. Fire Blast is a powerful Fire-type move with excellent coverage. It annihilates common steel-types such as Escavalier and Bronzong, both of whom can easily take Mew's Psychic STAB. Aura Sphere provides similar coverage and hits Dark-types hoping to switch in for free. It is especially useful for Houndoom who can otherwise wall Mew. Giga Drain and Dark Pulse round off Mew's coverage; the former lets Mew annihilate bulky Water-types such as Blastoise and Milotic while also offsetting Life Orb recoil. Dark Pulse on the other hand, lets Mew defeat Ghost-types and fellow Psychic-types.
[ADDITIONAL COMMENTS]
The standard offensive EV spread and Timid nature is employed to give Mew as much power as possible while also letting it hit the all important base 100 Speed bracket where other threats, such as, Zapdos reside. The remaining EV's are placed in Special Defense so Porygon 2 and Porygon Z cannot obtain Special Attack boosts upon switching in. A bulkier EV spread of 240 HP / 128 SpA / 4 SpD / 136 Spe with a Timid nature takes advantage of Mew's respectable bulk to set up much more easily while boasting similar power. A Life Orb is the main item as despite Mew's ability to double its Special Attack, it often lacks power without boosts, necessitating the Life Orb. However, Leftovers are still viable, especially on bulkier EV spreads that can take hits while setting up. A Lum Berry is also viable, being especially useful against walls that rely on status to slow down Mew. Pokemon such as Slowbro and Suicune who attempt to Toxic stall Mew will find themselves against a +2 healthy Mew once Lum Berry has been activated. Since Nasty Plot Mew has incredible coverage against most special walls, partners that appreciate walls being removed, such as Raikou, are especially good teammates for Mew.
- Standard EV spread is standard
- 4 SpD EVs so Porygon2/Z cannot get a download boost
- Bulky spread yeahhhhh 240 HP / 128 SpA / 4 SpD / 136 Spe; Timid @ Leftovers
- Timid for that all important Speed tier
- Life Orb is the main item as base 100 SpA isn't super good
- Leftovers takes advantage of Mew's bulk
- Lum Berry can be used to set up on things like Slowbro and Snorlax without fearing paralysis.
- Great wallbreaker as well, being able to decimate common special walls such as Snorlax, Umbreon, and Togekiss for teammates like Raikou
- Struggles against Bronzong without Fire Blast, and other bulky Psychic types without Shadow Ball

name: Swords Dance
move 1: Swords Dance
move 2: Zen Headbutt
move 3: Drain Punch
move 4: Sucker Punch
item: Life Orb / Leftovers

evs: 112 HP / 252 Atk / 8 SpD / 136 Spe
[SET COMMENTS]
While Mew can pull off a destructive Nasty Plot set coming off its Special Attack stat, it can be equally deadly with a Swords Dance set. While its base 100 Attack may seem to put Mew at a disadvantage compared to more powerful sweepers such as Mienshao and Darmanitan, Mew makes up for its offensive shortfalls with superior bulk and excellent versatility. What makes Mew a powerful sweeper is its excellent movepool and unpredictability. An opponent expecting a special attacking or defensive Mew will quickly find themselves exposed after letting Mew obtain a Swords Dance boost.
however, that isn't to say that Mew relies entirely on its unpredictability; even a known Swords Dance Mew can become a dangerous threat if left unchecked. Zen Headbutt is a powerful STAB move which, in conjunction with Mew's decent Speed, has a good chance to flinch the opponent. Drain Punch compliments Mew's STAB, being able to pulversie Dark-types that shrug off Mew's Psychic assaults. Its ability to heal Mew should not be underestimated as it allows Mew to restore health lost when setting up as well as mitigate Life Orb recoil. This passive recovery along with Mew's natural bulk means Mew is far more bulky than other common sweepers, such as Mienshao and Weavile. Lastly, Mew rounds out its coverage with Sucker Punch which hits Psychic-types that resist Zen Headbutt and Drain Punch. A powerful priority move in Suck er Punch lets Mew strike first against common Chocie Scarf holders such as Chandelure as well as beating Pokemon that naturally outspeed Mew. With perfect coverage, health regeneration, and priority, Mew is an extremely self-sufficient sweeper.
[ADDITIONAL COMMENTS]
An Adamant nature along with the suggested EV spread allows Mew to outspeed Adamant Heracross, maximizes attacking poiwer, and gives Mew more bulk. A few EVs are placed in Special Defense so Download Porygon 2 and Porygon Z are stuck with useless Attack boosts when switching in. WIP The choice between Life Orb and Leftovers depends mostly on how you want Mew to be played. Drain Punch somewhat reduces Life Orb recoil, and allows Mew to hit hard with little drawback. However, the combination of Drain Punch recovery and Leftovers keeps Mew alive against heavy harassment that would otherwise prevent Mew from sweeping. If you opt to use a more offensive EV spread than Life Orb is the recommended choice, bulkier EV spreads prefer Leftovers.
Although Mew has perfect coverage and immense power with Swords Dance, it still struggles against incredibly bulky walls and Pokemon who can dodge Sucker Punch. Cofagrigus can take Mew's attacks well enough to burn it with Will-O-Wisp and can hit it super effectively. Sableye can wall Mew by virtue of its typing which renders Zen Headbutt and Drain Punch useless. In return, Sableye can burn Mew and stall it out with Recover. Faster Pokemon that use Substitute can outpredict Mew by setting up a Substitute when Mew uses Sucker Punch, or hit Mew first if Mew doesn't use its priority move.

[SET COMMENTS]
At first, it may seem a shame to waste Mew's attacking capabilities for a generic supporting set; however, Mew's bountiful movepool comes to its aid once again, allowing Mew to shut down many powerful metagame threats. Unlike pokemon whose sole purpose is to lay down entry hazards or Toxic stall the opponent, Mew acts more like a team pivot; the Pokemon to switch in when you don't know what else to do. Unlike passive stallers, Mew can actively help your teammates with Taunt, which prevents the setting up of entry hazards, set up moves such as Calm Mind and Swords Dance, and status. Mew can easily force walls to switch out, allowing your teammates to switch in unscathed. Softboiled is a reliable recovery move that keeps Mew healthy and lets it keep up a permanent Taunt cycle. Will-O-Wisp cripples most physical attackers and in conjunction with Taunt and Softboiled, will let Mew stall out both walls and sweepers. Recovery moves and stat boosting moves will be disabled by Taunt, and the opponent will be forced to attack Mew; attacks which can be shrugged off with Softboiled. Psychic is Mew's only attack, and prevents Mew from being completely useless when Taunted.
[ADDITIONAL COMMENTS]
176 Speed EVs and a Timid nature allow Mew to outspeed Timid Roserade and either Taunt it, and thus prevent Sleep Powder or Spikes, or deal heavy damage with Psychic. The Speed EVs also allow Mew to outspeed Nidoking and counter it. HP is then maxed to provide the best overall bulk for Mew with the remaining EVs going in either Defense or Special Defense. The 80 EVs are most often best placed in Defense as Mew's typing allows it to counter powerful Fighting-types such Hitmontop, Machamp, Cobalion, and Virizion, all of which are comfortably shut down by Mew. However, the EVs can be placed in Special Defense if your team struggles with powerful special attackers such as Nidoking and Togekiss, the later of which is shut down by Synchronize if it tries to Paralyze Mew. As support Mew has no investment in its offenses, it struggles to do much significant damage with Psychic; instead, Mew can use Seismic Toss for more reliable breaking of Substitutes and a stronger attack against Dark-types and most Psychic-types. However, Seismic Toss leaves Mew more vulnerable to Ghost-types and Pokemon that can set up Substitutes with more than 100 HP.
[SET]
name: Baton Pass
move 1: Baton Pass
move 2: Taunt
move 3: Rock Polish
move 4: Nasty Plot / Swords Dance
item: Leftovers
nature: Timid
evs: 252 HP / 4 SpD / 252 Spe
[SET COMMENTS]
In a tier where every Pokemon has high powered attacks, crippling entry hazards, or debilitating status, it can be hard to fit a purely supporting Pokemon on your team. However, a well played Baton Pass Mew can easily set up a devastating sweep, ending games before the opponent has any time to react. Taunt is a staple move as it stops many traditional counters to Baton Pass, such as Roar, Whirlwind, status, and other Taunt users. Rock Polish and either Nasty Plot or Swords Dance in conjunction, can turn a threatening Pokemon in a wrecking ball capable of rolling over teams. However, it can be difficult to set up both if your opponent is competent. Rock Polish by itself it great for supporting slow but powerful Pokemon such as Chandelure and Nidoking, both of whom can annihilate teams once their glaring lack of Speed is rectified. A single Nasty Plot or Swords Dance can skyrocket the power of many Choice Scarf users and naturally fast Pokemon such as Crobat and Raikou.
[ADDITIONAL COMMENTS]
Speed is always maximized so Mew can get off a crucial Taunt, boost, or Baton Pass as often as possible. The remaining EVs are allocated towards HP so Mew is more survivable. Barrier and Amnesia are defensive boosting moves that Mew can use and pass on to others. While they give no offensive boost to the receiver, they are excellent if Mew is leading a Baton Pass chain as the recipients will be significantly harder to take down, and the chain less likely to be broken. Defensive boosting moves can also be useful if you wish to pass towards a bulky booster such as Snorlax who can easily use Curse along with the boosts provided by Mew to become an unstoppable steam roller. Calm Mind is a lesser boosting move that raises both Special Attack and Special Defense; it is also useful in Baton Pass chains and can be better than Nasty Plot and Swords Dance for receivers who rely on their tankiness as opposed to Speed.
[Other Options]
With such a wide movepool and excellent base stats, it should come as no surprise that Mew has plenty of viable options. Choice Specs and Choice band can turn Mew into a deadly wall breaker that can take advantage of its many coverage moves to hit most walls super effectively. On the other hand, a Choice Scarf lets Mew outspeed all of the unboosted metagame and revenge kill a plethora of threats with its outstanding coverage. Choice Scarf Mew can easily be catered to your teams needs; shoring up any weaknesses and vulnerabilities to certain sweepers. A dedicated lead said consisting of Stealth Rock, Explosion, and Taunt can be used to quickly set up Stealth Rock while preventing the opponent from doing the same. However, the dedicated lead is often not as useful due to team preview and can be better done by Azelf who has a similar move set and stronger attacking stats. Of course, these are just a couple of the options Mew can run, Mew can learn any TM and move tutor move, so if it exists, Mew can use it.
[Checks and Counters]
Due to Mew's versatility, countering it largely depends on the set. Once Mew has revealed what moves it is running, the appropriate counter or check can be brought in. Choice Scarf wielding revenge killers, such as Chandelure, Heracross, Krookodile, and Darminatan, can shut down both the Nasty Plot and Swords Dance sets but have to be wary of Sucker Punch on the latter. Such is Mew's power that none of the above should risk switching into Mew directly. Weavile and Zoroark outspeed Mew naturally and are both immune to its STAB attacks while being able to hit Mew super effectively with their own. Keep in mind though that Choice Scarf Mew outspeeds many of its traditional counters and can deal hefty damage. Sableye, through virtue of its typing and movepool, can easily shut down support and Baton Pass Mew with Taunt, while also being able to completely wall Swords Dance Mew. Unfortunately, Nasty Plot Mew is unphazed by Burn and can easily destroy Sableye. Slowking fairs decently against most Mew variants but can be OHKOed by a +2 Giga Drain and can do little but Dragon Tail or fish for Scald burns against Taunt. Cofagrigus beats most Mew variants but cannot stomach a Nasty Plot boosted Dark Pulse, it can otherwise remove boosts with Haze and set up Trick Room and Nasty Plot to turn the tables against Mew.
Now that I'm done with Zapdos, I'll take this over.
