[OVERVIEW]
With the highest Special Attack in the game, incredible Speed that allows it to outspeed almost all offensive threats in the metagame, and access to a plethora of power-bolstering abilities, Mega Mewtwo Y is one of the biggest threats in the Balanced Hackmons metagame. With various options including Protean and No Guard, Mega Mewtwo Y is very unpredictable and extremely versatile. Mega Mewtwo Y also has decent bulk, and although it is very lacking physically, it can survive some powerful special attacks and has Protean to change its typing to resist attacks from slower foes and priority attackers. Despite being the pinnacle of special attackers, though, Mega Mewtwo Y cannot switch in easily, forcing teams to run defensive support to provide it with safe opportunities to switch in.

Moves
========
Judgment is Mega Mewtwo Y's main attacking move and, coupled with Spooky Plate, becomes a 120 Base Power Ghost-type move that hits incredibly hard after gaining a STAB boost from Protean. Judgment is also very useful for Imposter Chansey; Chansey's Judgment will remain Normal-type, so it cannot touch Ghost-type Mega Mewtwo Y. Secret Sword provides very solid coverage alongside Ghost-type Judgment and allows Mega Mewtwo Y to hit Normal- and Dark-types that resist its Judgment. Secret Sword also prevents Imposter Chansey from attacking Ghost-type Mega Mewtwo Y. Quiver Dance allows Mega Mewtwo Y to boost its Special Attack, Special Defense, and Speed to incredible levels with the goal of sweeping. Boomburst is extremely powerful and allows Mega Mewtwo Y to hit the likes of Mega Audino and Yveltal, both of which are neutral to the combination of Ghost-type Judgment and Secret Sword. Infestation can also be used as a way to beat Shedinja while still being able to beat Imposter users. King's Shield is necessary, as it allows Mega Mewtwo Y to handle -ate ability users. It can potentially weaken contact attackers and also changes Mewtwo Y into a Steel-type, which provides it with an opportunity to safely attack.
Set Details
========
Protean is what makes Mega Mewtwo Y so threatening, granting it STAB on all of its attacks and thus bolstering its damage output to ridiculous levels; it also increases Mega Mewtwo Y's longevity, as it can switch types to resist incoming attacks. Spooky Plate is needed to make Judgment Ghost-type, which provides Mega Mewtwo Y with a reliable STAB move and prevents Imposter Chansey from checking this set. Maximum Speed and Special Attack investment is essential, as Mega Mewtwo Y needs to be as fast as possible and needs its damage output maximized.
Usage Tips
========
Although Mega Mewtwo Y has decent Special Defense, it still struggles to switch into even resisted attacks. When Mega Mewtwo Y is sent in, it is usually safe to use Judgment against most Pokemon outside of Normal- and Dark-types, against which Mega Mewtwo Y should use Secret Sword. King's Shield should be used to scout for powerful contact and priority moves. It can provide Mega Mewtwo Y with nifty resistances that usually let it use the appropriate attacking move against the foe without taking too much damage in return. King's Shield should not be overused, though, as it can provide free turns for the foe to set up or use crippling status moves. When using Mega Mewtwo Y, scout the opponent's team for their support Pokemon in order to prevent Mega Mewtwo Y from being crippled by Prankster Spore, as it becomes easy to take down once it is put to sleep. When facing Imposter Chansey, keep Mega Mewtwo Y as a Ghost-type so that Chansey cannot touch it. Only use Quiver Dance once the opportunity arises so that you do not have to worry about the Speed tie, switch Mewtwo back to Ghost-type whenever you expect the foe to attack, and slowly whittle Chansey down with Secret Sword.
Team Options
========
This set lacks the need for offensive support because it is very independent and capable of functioning by itself; however, it requires defensive support. Bulky pivots such as Registeel, Giratina, and Mega Audino can bring in Mega Mewtwo Y safely with U-turn, Volt Switch, and Baton Pass. They can also provide healing if Mega Mewtwo Y is weakened too much and can set up entry hazards to check Shedinja, which walls Mega Mewtwo Y lacking Infestation or Magma Storm. Your own answer to Protean Mega Mewtwo Y is absolutely essential, as this set can still lose to Imposter Chansey through bad luck or poor predictions. An example is Fur Coat Chansey, which can repeatedly come in on Mega Mewtwo Y, heal off the damage, and threaten to cripple it. Prankster coupled with Spore is capable of shutting down Mega Mewtwo Y, and specially defensive Pokemon such as Poison Heal Kyogre, Ho-Oh, and Yveltal are capable of switching in and weakening it. Because this set functions best as a late-game cleaner, wallbreakers such as Tail Glow Dialga make for decent teammates for their ability to crush opposing walls. As Judgment loses functionality without Spooky Plate, a Knock Off absorber such as Mega Audino is needed. Mold Breaker users such as Mega Gengar can remove Shedinja for Mega Mewtwo Y should it lack infestation. Strong physical attackers such as Arceus and Mega Rayquaza can wear down the likes of Mega Audino and Fur Coat Chansey for Mega Mewtwo Y.

[SET COMMENTS]
Moves
========
Boomburst is Mega Mewtwo Y's main attacking move, as it is the strongest perfectly accurate special attack in the game and is boosted even further by Protean and potentially Life Orb. Moonblast is used as Fairy-type coverage, allowing Mega Mewtwo Y to hit Mega Mewtwo X and many common Dark- and Dragon-types in the metagame super effectively, as well as changing its typing to weaken incoming Dark-type moves and gain an immunity to Dragon-type moves. Earth Power hits Steel- and Poison-types that can otherwise switch in easily, and it is capable of hitting Rock-types such as Mega Diancie as well. Magma Storm can also be used, providing Mega Mewtwo Y with more powerful coverage to hit Steel-types and a means to beat Shedinja. King's Shield is necessary to improve Mega Mewtwo Y's matchup against priority users and give it safer opportunities to attack, as it temporarily becomes a Steel-type upon using the move.
Set Details
========
Protean is what makes Mega Mewtwo Y so threatening; it provides it with a STAB boost to all of its attacking moves, significantly boosting its damage output, and allows it to change types to reduce damage from faster attacks, increasing Mega Mewtwo Y's longevity. Safety Goggles allows Mega Mewtwo Y to avoid Spore from Prankster users trying to shut it down. Life Orb can be used instead to bolster its attacks even further, making it incredibly difficult to wall coupled with its coverage. Maximum Speed and Special Attack investment is essential in order to Speed tie with opposing Mega Mewtwo Y and outspeed everything slower. Special Attack is maximized for maximum damage output.
Usage Tips
========
Unlike sets running Judgment, this set isn't capable of beating Imposter Chansey one-on-one; instead, it fills a hit-and-run role, dealing huge damage with its coverage moves to opposing Pokemon that its teammates have trouble breaking through. If the opponent has a Chansey, avoid keeping Mega Mewtwo Y on the field for too long, as it can severely punish your team by using Mega Mewtwo Y against it. Mega Mewtwo Y lacks the bulk to switch in repeatedly, so avoid switching it in too often and especially avoid powerful attacks. Once Mega Mewtwo Y is safely on the field, Boomburst should be used, as it is Mega Mewtwo Y's most effective attack, though other moves can be used depending on the opposing Pokemon. Mega Mewtwo Y is capable of 2HKOing the entire metagame outside of dedicated walls, so it isn't heavily reliant on prediction. King's Shield should be used against predicted contact attacks and to scout priority attacks. It can lower the foe's Attack stat and temporarily changes Mega Mewtwo Y to a Steel-type to resist the incoming priority attack the following turn. Avoid using King's Shield too much, as it can provide the foe with free turns to either set up or hit Mega Mewtwo Y with a status move. Scout the opponent's team for support Pokemon and avoid Pokemon with Prankster Spore if Mega Mewtwo Y lacks Safety Goggles.
Team Options
========
This set is designed to offer team-dependent offensive coverage to other sweepers, so there is no particular offensive teammate that pairs exceptionally well with it. Bulky Pokemon such as Registeel, Giratina, and Mega Audino can use pivoting moves to provide Mega Mewtwo Y with safe switches in. They can also heal it with Wish and Heal Bell and provide entry hazard support to cover the likes of Shedinja, which is capable of walling this set should it lack Magma Storm. An answer to opposing Protean Mega Mewtwo Y is necessary, as Imposter Chansey can punish teams unprepared for it. Prankster Spore users and Pokemon such as Poison Heal Kyogre, Ho-Oh, and Yveltal can all handle Chansey that have transformed depending on Mega Mewtwo Y's coverage. Strong physical attackers such as Mega Diancie and Arceus can help wear down the likes of Mega Audino and Fur Coat Chansey, which can get in Mega Mewtwo Y's way. Mold Breaker teammates with Pursuit are appreciated if Mega Mewtwo Y lacks Magma Storm for Shedinja.
[STRATEGY COMMENTS]
Other Options
=============
Any type of coverage move can be run on the Protean set, as Mega Mewtwo Y's coverage is team dependent. A different Protean set with Fist Plate, Judgment, and coverage moves of types that are weak to Fighting, such as Boomburst, Power Gem, Ice Beam, and Doom Desire, is effective in that it prevents Imposter users from revenge killing Mega Mewtwo Y, as they cannot hit it super effectively after King's Shield, whereas Mega Mewtwo Y is able to hit them super effectively with Judgment. No Guard with Lum Berry can be used with Sing, Zap Cannon, Inferno, and another low-accuracy move. Dynamic Punch can be used with a Naive nature to allow Mega Mewtwo Y to spread status ailments quickly and disturb the opposing team's momentum. Tinted Lens-boosted Future Sight is incredibly powerful, but Mega Mewtwo Y functions more like a hit-and-run Pokemon and wants immediate power. A Contrary set with attacks such as Psycho Boost, Overheat, Leaf Storm, and Draco Meteor can be used, but it faces competition from physically attacking Contrary users and is very weak to Chansey and Shedinja. However, it can 2HKO the entire metagame easily after a single boost. The combination of Simple and boosting moves such as Shell Smash and Quiver Dance can be used but is very weak to Chansey, and other Pokemon can fill this role better due to Mega Mewtwo Y's poor typing. Random support moves such as Spore can be used to catch the opponent off guard, but Mega Mewtwo Y doesn't have the room for them. Judgment can be used with specific Plates in place of a coverage move, such as Pixie Plate with Judgment instead of Moonblast. Mega Mewtwo Y with an -ate ability hits extremely hard and has coverage for foes that resist Ice-, Flying-, or Fairy-type moves, though it cannot change types and thus is stuck with its mediocre Psychic typing. Steam Eruption can be used to cripple and wear down switch-ins with a possible burn and is capable of hitting Rock-types if Mega Mewtwo Y lacks the coverage to hit them. Seed Flare is a useful option for breaking through Water-, Rock-, and Ground-types and, coupled with its dangerous secondary effect, allows Mega Mewtwo Y to easily break through opposing walls. With Protean, it also provides Mega Mewtwo Y with a temporary immunity to Spore and Leech Seed.
Checks and Counters
===================
**Priority Attackers**: Mega Mewtwo Y relies on its high Speed to overpower its foes, so priority is one of the best ways to take it down. -ate ability users such as Mega Diancie and Mega Rayquaza can easily KO it or force it out with their strong attacks boosted by their -ate abilities. Gale Wings sweepers can also deal significant amounts of damage to Mega Mewtwo Y. However, contact priority moves are risky, as Protean Mega Mewtwo Y always carries King's Shield, allowing it to lower the Attack of revenge killers and even convert to a Steel-type for a turn and resist the second iteration. Prankster users are also great checks to Mega Mewtwo Y. Topsy-Turvy users check boosting sets by reversing the stat boosts, and Prankster Spore is a reliable way to shut Mega Mewtwo Y down temporarily, as it rarely runs items such as Safety Goggles and Lum Berry in favor of more offensive items. Once Mega Mewtwo Y is crippled, it is far easier to take down with a teammate. Sucker Punch users such as Mega Tyranitar, Yveltal, Mega Gyarados, and Protean Mega Mewtwo X can also KO Mega Mewtwo Y provided that it has taken enough prior damage.
**Imposter Chansey**: Imposter Chansey can check Mega Mewtwo Y with a little bit of Speed tie luck. Chansey beats the non-Judgment set easily, forcing it out and gaining massive amounts of momentum. However, it loses to the Judgment set unless it can get lucky with Speed ties.
** Fast Attackers**: Powerful Pokemon that can outspeed Mega Mewtwo Y can check it so long as they switch in safely. Deoxys-A and Mega Aerodactyl can outspeed and KO Mega Mewtwo Y, and with the right coverage moves, they can maneuver past King's Shield on Protean sets as well. Unfortunately, these Pokemon have limited viability otherwise.
**Extremely Bulky Pokemon**: It requires a lot of natural bulk for a Pokemon to be able to tank multiple hits from Mega Mewtwo Y, but some Pokemon can do it. Fur Coat Chansey is an excellent example, as it shrugs off the attacks from both of Mega Mewtwo Y's sets fairly easily depending on the coverage and can gradually wear Mega Mewtwo Y down or even KO it with Metal Burst. Poison Heal Mega Audino is also an excellent check, as it can easily shrug off hits from the Judgment Protean set and phaze it should it try to set up. Poison Heal Yveltal is a reliable check to the Judgment Protean set as well, as it can sponge Judgment and Secret Sword continuously and hit Mega Mewtwo Y hard with its STAB attacks. Ho-Oh resists Moonblast, is immune to Earth Power, and has very high special bulk, meaning that it is capable of switching into Mega Mewtwo Y.
**Knock Off Users**: Besides dealing super effective damage, Knock Off can cripple the Judgment set by removing the Spooky Plate that makes Mega Mewtwo Y's Judgment Ghost-type. Without its Spooky Plate, Mega Mewtwo Y struggles to even scratch most Ghost-types, and Pokemon such as Giratina, Mega Gengar, Aegislash, and even Imposter Chansey can check it far more easily. However, due to Mega Mewtwo Y's immense offensive presence, it is not always easy to successfully hit it with Knock Off without risking losing a Pokemon.
**Shedinja**: Shedinja is a good check to the Judgment set if it lacks Infestation or Magma Storm and can check the non-Judgment set as well. It is important to scout Mega Mewtwo Y's set, however, before trying to confront it with Shedinja.
**Choice Scarf Users**: Choice Scarf users that can hit Steel-types super effectively with non-contact moves can function as solid lures to beat Mega Mewtwo Y.
