[Zrp200]

I can't stamp GP checks, so someone from GP should come around and stamp this at some point.

* (add space) Possessing an earth-shattering 194 Special Attack stat, outrunning Speed sufficient to outrun most Pokemon in the metagame, while having and coverage for it’s its checks, (AC) Mega Mewtwo Y is a very threatening wallbreaker for balance and bulky offence offense teams.

* After a boost, Psystrike is able to<OHKO OHKO specially bulky Pokemon such as defensive Primal Kyogre and Calm Mind Arceus-Ground after Stealth Rock and Ho-Oh after minor chip.

* (Add Space) Fire Blast OHKOes Steel types such as Ferrothorn and, after Stealth Rock, Necrozma-DM QC - Necrozma-DM is only OHKOed by +2 Fire Blast even at 0/0 and Zacian-C. After a boost, it also OHKOes Calyrex-I and Necrozma-DM moved from earlier after a boost moved to the start of the sentence to avoid implying that only one is OHKOed after a boost. This whole paragraph is just QC changes.

* (Add Space) Ice Beam allows Mega Mewtwo Y to hit Yveltal (RC) while also dissuading Pokemon such as Mega Salamence, Zygarde, and Rayquaza from switching into an unscouted Mega Mewtwo Y. Focus Blast allows Mega Mewtwo Y to threaten Arceus-Dark and while providing coverage for defensive Necrozma-DM Focus Blast does not hit Necrozma-DM as hard as Fire Blast does, and it is less accurate. However, no matter which coverage move is chosen, Mega Mewtwo Y will have a problem with either Arceus-Dark or Yveltal which that must be accounted for with teammates.

* (Add Space) 88 Def EVs allow Mega Mewtwo Y to survive Life Orb Marshadow's Shadow Sneak, while 216 Speed EV‘s EVs lets Mega Mewtwo Y outspeed Flutter Mane and Chien-Pao while also ensuring that base Mewtwo outspeeds Marshadow. It’s not always required to immediately Mega Evolve, as Mega Mewtwo Y's reduced Defense (remove space) may allow Choice Band Marshadow’s Shadow Sneak and Arceus-Dark's Foul Play to OHKO Mega Mewtwo Y it. Unnerve can also be useful to deal with Custap Berry Arceus and Lem Berries if paired with a teammates with Toxic Spikes Base Mewtwo's Unnerve may also prove very situationally useful to prevent berries from being used against Mewtwo such as in the case of Chople Berry Arceus when running Focus Blast or in forcing initial poison damage on Lum Berry users from Toxic Spikes QC - Replaced with a shorter version of the suggestion from my QC check. this is not how I expected this to be implemented; the first berry should have been Chople Berry. Also, this implementation did not express that these instances are very rare and situational occurrences: the former case accounts for about 1 in 50 Arceus, and only for Focus Blast Mewtwo, while the latter case is slightly more common, but much more situational and requires Eternatus as a teammate. However, Mega Mewtwo Y is required to Mega Evolve to outspeed threats like offensive Eternatus.

* (add space) Mega Mewtwo Y should be used as a wallbreaker in the early- and mid game mid-game,; replace comma with semicolon removing Pokemon such as defensive Necrozma-DM and defensive Arceus-Ground can help its teammates sweep late-game. It Mega Mewtwo Y has the potential to sweep, but it doesn't do so consistently, as it runs into many roadblocks, such as priority from Marshadow and Yveltal.

* (add space) Other offensive Pokemon such as Zacian-C and Meteor Beam Eternatus appreciate Mega Mewtwo Y breaking down checks such as Primal Groudon and defensive Necrozma-DM for them to potentially sweep.

* Arceus-Fairy and defensive Eternatus are amazing partners, (AC) as they can switch into Mega Mewtwo Y’s biggest checks in Marshadow, Arceus-Dark, and Yveltal. Defensive Zygarde can also be a great partner to handle Marshadow, and it may even be able to handle Zacian-C and Yveltal depending on moveset and Zygarde's Tera type.

There were a few more QC things that came up when reviewing this. They're marked pretty explicitly, and are in slightly lighter colors.
