[OVERVIEW]
Mega Mewtwo Y is one of the best Pokemon in the Balanced Hackmons metagame thanks in part to its unparalleled Special Attack, which helps it hit extremely hard with its STAB moves, and its great base Speed, which helps it outspeed nearly the entire Balanced Hackmons metagame, allowing it to threaten out many slower attackers. Mega Mewtwo Y also has very good Attack, meaning that it can effectively use mixed sets. However, Its Psychic-type STAB moves hit no common Pokemon super effectively save for Mega Gengar, and they are resisted by common Dark- and Steel-types such as Yveltal, Mega Tyranitar, and Registeel. Because of this, it relies on non-STAB coverage moves to beat many common threats. Additionally, the presence of Flash Fire Steel-types in the metagame hinders the viability of Mega Mewtwo Y sets that rely on Fire-type coverage. Mega Mewtwo Y's Psychic typing and relatively low Defense cause it to take lots of damage from moves commonly seen on defensive Pokemon, like U-turn, Spectral Thief, and Knock Off. Pokemon like Mega Tyranitar and Yveltal can also switch in on Mega Mewtwo Y's Psychic-type moves and deal lots of damage with Pursuit.

Moves
========
Psycho Boost is Mega Mewtwo Y's strongest attack, and thanks to Contrary it raises Mega Mewtwo Y's Special Attack by two stages. Fleur Cannon provides coverage for Dark-types like Yveltal and Mega Tyranitar, OHKOing them at +2 unless they have Unaware. Pixie Plate Judgment, although it is weaker than Fleur Cannon and doesn't have the benefit of raising Mega Mewtwo Y's Special Attack, allows this set to be easily imposter-proofed with Dark-types like Unaware Mega Gyarados and Sand Stream Mega Tyranitar. Overheat hits Steel-types like Registeel, preventing them from walling Mega Mewtwo Y. Magma Storm KOs Sturdy Shedinja by trapping it and hits Steel-types hard, but it's somewhat weak and inaccurate. Additionally, it doesn't boost Mega Mewtwo Y's stats. V-create raises Mega Mewtwo Y's defenses and Speed, making it harder to revenge kill, but it doesn't use Special Attack boosts from Mega Mewtwo Y's other attacks, meaning that it can miss KOs on Steel-types and get forced out by Spectral Thief. Moongeist Beam hits Psychic-types and Sturdy Shedinja, and it can also beat unresistant Unaware users like Primal Kyogre after Mega Mewtwo Y has accumulated enough boosts. Encore helps give Mega Mewtwo Y setup opportunities by locking the foe into a useless move like Shore Up, and also prevents Prankster Destiny Bond users from taking Mega Mewtwo Y down with them. However, it makes Mega Mewtwo Y much harder to imposter-proof. Lovely Kiss has a chance to give Mega Mewtwo Y free turns by putting the foe to sleep. It is used over Spore because it ignores Safety Goggles and Grass-types' natural immunity.
Set Details
========
A Speed-increasing nature is used on Mega Mewtwo Y to outspeed as many foes as possible, preventing Pokemon like Mega Mewtwo X and Mega Gengar from revenge killing it. Contrary turns Fleur Cannon, Psycho Boost, and Overheat into high-powered moves that also help Mega Mewtwo Y snowball, instead of one-time nukes. Life Orb helps Mega Mewtwo Y get key OHKOs and 2HKOs it wouldn't otherwise, such as against RegenVest Primal Kyogre. Focus Sash is used so Mega Mewtwo Y can stop Shell Smash sweepers as a last resort. It also helps Mega Mewtwo Y survive a single attack from Imposter Chansey and hit it back in return with Moongeist Beam. Pixie Plate changes Judgment into a Fairy-type attack, although it stays Normal-type when used by opposing Imposter users unless they too carry a Plate. This allows Mega Mewtwo Y to be easily Imposter-proofed with a Dark-type. Wide Lens can be used to increase Mega Mewtwo Y's consistency by reducing the chances that its moves will miss, but this item loses out on the benefits of Mega Mewtwo Y's other potential items.
Usage Tips
========
To maximize Mega Mewtwo Y's chances of sweeping, conceal its set by not using it early-game. If possible, bring Mega Mewtwo Y in against a foe that gets KO'd by one of its attacks, so it can begin sweeping without first taking damage. Unless Choice Specs is used, there is little prediction involved in attacking with Mega Mewtwo Y. Even if the opponent switches their Pokemon into a resisted move, Mega Mewtwo Y can usually KO them on the next turn thanks to its Special Attack boost. Imposter users are the biggest obstacle to Mega Mewtwo Y's sweep, so try to wear them down before sending it in.
Team Options
========
Counterplay to Imposter users is necessary to prevent them from sweeping. On defensive teams, sturdy Unaware users like Muk-Alola, Chansey, and Ho-Oh work well; on offensive teams, Pokemon with Prankster Destiny Bond or Focus Sash, like Shell Smash Yveltal and Prankster Kartana, work well. Focus Sash Spore Contrary Mega Sceptile can break past the foes that would normally stop Mega Mewtwo Y, like Prankster Destiny Bond and Imposter. It can also imposter-proof Mega Mewtwo Y, and take advantage of the holes it creates to sweep. Poison Heal users like Regigigas and Xerneas synthesize well with Mega Mewtwo Y, because it can put foes to sleep, providing Mega Mewtwo Y with free setup opportunities.

Moves
========
When boosted by Sheer Force, Psychic is able to 2HKO most unresistant walls. Moonblast provides coverage against Dark-types and hits miscellaneous targets harder, cleanly OHKOing Mega Mewtwo X and 2HKOing Assault Vest Giratina. Bug Buzz hits less targets than Moonblast and misses out on hitting Yveltal, but it has the benefit of easily 2HKOing Cresselia and opposing Mega Mewtwo Y and OHKOing Mega Slowbro. Additionally, it does lots of damage to other Dark-types and Imposter. Focus Blast hits Fur Coat Chansey, Steel-types, and Dark-types hard, and OHKOs Mega Tyranitar, but its low accuracy holds it back. Ice Beam hits Yveltal and Dragon-types like Giratina, and cleanly OHKOs Zygarde-C variants without Assault Vest. However, it necessitates the use of Bolt Strike to hit Mega Gyarados and RegenVest Primal Kyogre. Earth Power 2HKOs most Steel-types, but misses out on Celesteela. It also has a chance to OHKO Red Orb Groudon. Blue Flare hits all common Steel-types super effectively, unless they have the Flash Fire ability. V-create is stronger than Blue Flare with a chance to OHKO RegenVest Solgaleo, but it lowers Mega Mewtwo Y's defensive stats and Speed; additionally, it causes it to take recoil damage from Life Orb. Bolt Strike is used for foes like Flash Fire Celesteela and RegenVest Primal Kyogre, cleanly OHKOing both. It also does significant damage to foes lacking physical bulk such as Chansey sets without Fur Coat. Moongeist Beam hits Psychic-types and Sturdy Shedinja, but its lack of a secondary effect makes it weaker than Mega Mewtwo Y's other attacks.
Set Details
========
The Sheer Force ability is used to give most of Mega Mewtwo Y's attacks a 30% boost while removing their secondary effects. This adds much-needed power to its coverage moves while not locking it into an attack. A Life Orb further boosts these attacks by 30%, and its recoil is mitigated on moves with secondary effects thanks to Sheer Force. If any physical moves are used, Naive is the preferred ability because it doesn't leave Mega Mewtwo Y more vulnerable to physical moves like U-turn and Spectral Thief. If no physical moves are used, Timid keeps Mega Mewtwo Y's defenses high while lowering its unused Attack.
Usage Tips
========
Bring Mega Mewtwo Y in by slow pivoting on Pokemon that can't threaten it much, like Primal Kyogre, Mega Audino, and Celesteela. Once Mega Mewtwo Y is in play, break the opposing team with its powerful attacks. Watch out for Prankster Destiny Bond users such as Registeel, because these Pokemon are often the only thing that can potentially stop Mega Mewtwo Y from breaking the entire opposing team.
Team Options
========
Pokemon like Volt Absorb Celesteela, Fur Coat Chansey, and Levitate Registeel can imposter-proof this set depending on the moves chosen. Utility Pokemon like RegenVest Primal Kyogre and Mega Tyranitar can pivot in Mega Mewtwo Y safely. Hazard setters like Red Orb Groudon help Mega Mewtwo Y by taking care of Sturdy Shedinja and helping Mega Mewtwo Y beat foes with Focus Sash. The chip damage on miscellaneous foes can also help Mega Mewtwo Y get KOs it would otherwise miss. Mold Breaker Pursuit users like Secret Sword Mega Gengar can eliminate Sturdy Shedinja, allowing Mega Mewtwo Y to take on these teams without being hard walled for the whole game.
[STRATEGY COMMENTS]
Other Options
=============
A Choice Specs set with Tinted Lens or Adaptability can work out well thanks to Mega Mewtwo Y's incredible Special Attack and arsenal of powerful STAB moves, but its offensive typing holds it back. Imposter users can switch in because they resist its STAB moves, Dark- and Steel-types are very common, and very few common Pokemon are hit super effectively by Psychic. Mega Mewtwo Y can use 0 Defense EVs and IVs along with a negative nature to allow a Dark-type to deal tons of damage to Imposter Chansey with Pursuit. However, the reduced bulk can be problematic against foes like RegenVest Giratina. Tail Glow is an option on the Sheer Force set that allows Mega Mewtwo Y to OHKO even very bulky Pokemon or those with beneficial typing, like Yveltal and Chansey, with its attacks. However, great care has to be taken to imposter-proof such sets, and the lack of a fourth attack restricts Mega Mewtwo Y's coverage. Choice Specs Mega Mewtwo Y can use utility moves like Revelation Dance to hit Normalize Gengar and Knock Off to remove items like Eviolite and Assault Vest if needed, but these take up precious moveslots and are inconsistent. Future Sight Mega Mewtwo Y can help other wallbreakers beat Pokemon that would normally wall them by effectively hitting twice in one turn, and it's more powerful when used with Adaptability. However, Mega Mewtwo Y can't viably use it with Choice Specs, and the lack of initial power is bad for it. A Shell Smash set can serve as a decent sweeper with Moongeist Beam, a coverage move, and Psystrike or Stored Power, but it fails to break common Prankster Haze users and is extremely vulnerable to Spectral Thief. Sets that take advantage of Mega Mewtwo Y's decent defenses and high Speed, like RegenVest, are viable, but they tend to face competition from bulkier Pokemon.
Checks and Counters
===================
**Dark-types**: Although most Mega Mewtwo Y sets carry coverage for these Pokemon, they still serve as decent checks. Pokemon like Yveltal and Sand Stream Mega Tyranitar can switch into a predicted Psychic-type move, withstand a single coverage move, and deal massive damage with Knock Off or trap Mega Mewtwo Y with Pursuit.
**Steel-types**: Common Pokemon like Registeel, Solgaleo, and Celesteela carry a resistance to Mega Mewtwo Y's STAB moves, and they often use Flash Fire, so Fire-type coverage isn't a reliable stop to them.
**Prankster Users**: Prankster Pokemon like Registeel can cripple Mega Mewtwo Y with Glare or remove it with Destiny Bond. They can also shut down the Shell Smash set with Haze.
**RegenVest Users**: Pokemon like Yveltal, Primal Kyogre, and Solgaleo can take a hit from Choice Specs Mega Mewtwo Y and force it out, and any damage they take is negated over time thanks to Regenerator. However, they struggle against Knock Off and Sheer Force variants.
**Imposter Chansey**: Thanks to Mega Mewtwo Y's naturally high Special Defense and Psychic resistance, Imposter Chansey can switch in a few times against Mega Mewtwo Y. However, it's put in a bad spot if it switches in on Shell Smash.
**Faster Pokemon**: Although they are uncommon, offensive Pokemon that outspeed Mega Mewtwo Y are solid checks to it. Contrary Mega Sceptile with Spore or Focus Sash can 2HKO Mega Mewtwo Y with its STAB moves, while Mega Beedrill and Pheromosa deal huge amounts of damage with U-turn or Megahorn.
**Priority Users**: -ate FakeSpeed users like Mega Rayquaza and Mega Diancie can threaten to KO Mega Mewtwo Y before it even moves, and Prankster users like Registeel can cripple it with moves like Glare or remove it with Destiny Bond. However, Dazzling variants are immune to priority altogether.
