Mega Mewtwo X

With a recognisably large Attack stat, it is no surprise that Mega Mewtwo X is one of the leading physical attackers in Balanced Hackmons. With vast and unpredictable coverage through the utilisation of Protean, it is able deal large amounts of damage to most of the metagame with relative ease. However, such power comes at a cost as it can be difficult to deal with opposing Imposter users which transform into Mega Mewtwo X. It also loses heavily to the few Pokemon that wall it. Ultimately, Mega Mewtwo X is still a powerful tool that can take apart teams when utilised well.

Moves
========
Precipice Blades provides good and strong coverage that defeats many common Pokemon in the metagame that are weak to Ground, such as Primal Groudon, Mega Diancie and a plethora of defensive Steel-types such as Registeel and Aegislash. Thousand Arrows can also be used as a more accurate option, however the damage output from Precipice Blades is generally more preferable. Bolt Strike is another powerful move that complements Ground-type coverage, allowing Mega Mewtwo X to take out Pokemon such as Primal Kyogre, Mega Slowbro and the occasional Flying-types such as Ho-oh and Yveltal. It is also used to hit Mega Rayquaza hard. Fusion Bolt is a more accurate alternative, however, similarly to Precipice Blades, the damage output from Bolt Strike is usually superior. V-create is useful in demolishing Pokemon that do not resist Fire, however it must be used sparingly as the stat drops can easily be taken advatange of by the opponent. ExtremeSpeed functions as useful priority that works best for picking off weakened Pokemon. Sucker Punch also acts as useful priority for defeating offensive Pokemon that Mega Mewtwo X may struggle to beat, such as Mega Gengar and Protean Mega Mewtwo Y. Draco Meteor hits Giratina sets hard, especially when boosted by a Life Orb, and can efficiently defeat other Dragon types such as Mega Rayquaza. King's Shield is essential, allowing Mega Mewtwo X to take on sets that run super effective priority such as Aerilate, Pixilate or Gale Wings; even if the opponent doesn't not suffer an Attack drop, the Steel typing from Protean allows Mega Mewtwo X to survive priority that it otherwise wouldn't.
Set Details
========
The given EV spread maximises offensive efficiency for Mega Mewtwo X. A Speed-boosting nature is necessary to outspeed everything that it can as not only does Protean render an Attack-boosting nature unnecessary, but the occasional Mega Rayquaza and Mega Diancie that also run Speed-boosting natures can severely dent Mega Mewtwo X, even when its typing is Steel from King's Shield. A Jolly nature is therefore the most practical choice. If Draco Meteor is being used, a Naive nature should be used as it gives Mega Mewtwo X a little insulation from physical priority. The 4 HP EVs should also be moved to Special Attack. Safety Goggles is the safer item choice, allowing Mega Mewtwo X to block Spore from common Prankter users such as Aegislash, but if more power is needed, Life Orb is the best option for boosting the power of all moves.
Usage Tips
========
When facing off priority users, do not be afraid to use King's Shield. It is almost always the safest option, unless it is highly likely your opponent will do something that will be problematic such as boosting stats or switching into another Pokemon that can defeat Mega Mewtwo X.
Team Options
========
The most important is a check to your own Mega Mewtwo X in case an Imposter-user transforms into it. This check may vary depending on the moves that are chosen, however bulky Fur Coat users that do not have a weakness to one of Mega Mewtwo X's moves are generally the best option. A check for Giratina is useful if Mega Mewtwo X does not run Draco Meteor, as it will be hard-walled by Giratina otherwise; examples of Giratina checks include Mega Diancie and Mega Gengar. Sturdy Shedinja hard-walls Mega Mewtwo X as the latter cannot afford to run moves that deal passive damage such as Infestation without severely limiting their coverage, thus strategies that eliminate Shedinja such as Stealth Rock and Pursuit Mold Breaker are recommended. Burns will completely cripple Mega Mewtwo X, thus a status-healing move is recommended on defensive Pokemon.
[STRATEGY COMMENTS]
Other Options
=============
Protean can effectively run any move that has a useful function; for example, Play Rough, Icicle Crash and Knock Off can hit non-Fur Coat Giratina sets hard and Crabhammer can guarantee a KO on Primal Groudon. A Refrigerate set can be used to surprise and defeat weak to Ice such as Mega Rayquaza, or frail offensive Pokemon such as Mega Gengar, as well as Giratina sets that don't run Fur Coat. Mold Breaker can be also be used in conjunction with Pursuit to defeat Sturdy Shedinja; Fighting STAB is what gives it a niche over other Mold Breaker users.
Checks and Counters
===================
**Giratina**: Giratina serves as Mega Mewtwo X's greatest check, especially Fur Coat sets; without Draco Meteor, there is nothing that Mega Mewtwo X can do due to the lack of super effective physical coverage available.
**Imposter-users**: The titanic bulk of Imposter-users almost always means that it will defeat Mega Mewtwo X, even if the latter wins the Speed tie. Additionally, if you are unable to check your own Mega Mewtwo X set or the check has fainted, then transformed Imposter-users will be free to sweep.
**Shedinja**: As was already mentioned, Mega Mewtwo X can't afford to run moves that defeat Shedinja without hindering its own coverage against the rest of the metagame.
**Fur Coat**: Also as previously mentioned, if it is a Pokemon that isn't weak to any of Mega Mewtwo X's moves, most bulky Pokemon with Fur Coat can check it, such as Giratina and Mega Audino.
