Though Mega Blastoise seems to have underwhelming stats but it is still able to beat many threats in the 1v1 metagame including Mega Gyarados, Donphan, Kyurem-Black and many more with the help of its great bulk allowing it to take a hit from almost any non super effective attack, its great typing which limits the amount of super effective hits it takes and a great ability in Mega Launcher accompanied by an excellent movepool which consists of good coverage as well as many of them being boosted by Mega Launcher such as Dark Pulse, Aura Sphere, and Dragon Pulse allowing it to secure KOs on bulkier foes. Fake Out allows it to get past Dragonite's Multiscale and Sturdy Pokemon such as Aggron, Donphan, and Golem. Hydro Cannon is Mega Blastoise's hardest-hitting STAB move which is powerful enough to grab KOes against most non-resistant foes. Though it comes with the recharge drawback but it matters much less in 1v1. However Blastoise's weakness to electric and grass gives it trouble against Tapu Koko and Mega Venusaur, both of which are very prevalent in the 1v1 metagame. Additionally, many other pokemon carry electric or grass coverage such as Mega Charizard Y, Metagross, and blastoise will most likely lose due to the opponents having these moves. It also loses to Choice Banded or bulky variants of Kyurem-Black carrying Fusion Bolt. Due to Blastoise's dissappointing speed tier it relies on its bulk to survive hits and KO the opponent, knowing this blastoise struggles to survive any boosted move without proper investment. Given all of these problems Blastoise has to face, it is still a notable special atracker capable of bringing teams together by patching up its weaknesses

Ability: Mega Launcher
EVs: 144 HP / 252 SpA / 112 Spe
- Fake Out
- Hydro Cannon
- Dark Pulse
- Dragon Pulse / Aura Sphere
Fake out is one of the most important moves as this allows blastoise to get damage of on Sturdy Pokemon and KO them with the appropriate move. Hydro cannon is the preferred stab move as this KOes most Sturdy Pokemon such as Aggron, Donphan, and Crustle after fake out damage and can also KO other pokemon that doesnt resist such as Mega Aggron, Mega Mawile, Mega Lopunny, and Mega Pinsir. Dark pulse is used as a move to hit Ghost- and Psychic-types most notably Gengar and Mega Slowbro. Dragon pulse is there so blastoise could beat Dragonite, Garchomp, and Kyurem-Black with ease, like dark pulse it is also able to act like a strong coverage move to be able to hit many things neutrally. Aura sphere can also be used to hit the likes of tyranitar and to get a strong hit on ferrothorn.
Maximum special attack and modest nature make it so that blastoise could hit as hard as possible aswell as to ensure it KOes Dragonite and Choice Scarf Kyurem-Black. The 112 speed investment is to ensure that you outspeed all Sturdy Pokemon exept timid magnezone. 144hp EVs are in place because it enables blastoise to take some strong hits such as one scarf Kyurem-Black fusion bolt and ko with dragon pulse. Its ability Mega Launcher allows all of its pulse moves boosted allowing it to have reliable coverage options capable of grabbing KOs on Pokemon that take super effective damage.
This set function as a great sturdy and multiscale answer thanks to the move fake out which is capable of braking Multiscale and Sturdy, while preventing any damage being done on the first turn. This may also function as a kyurem black check though not reccomended as kyurem black is capable of running a variety of sets such as choice band and weakness policy. It is also not recommended to send blastoise out if you see a powerful electric type such as tapu koko as you risk getting OHKOd by these pokemon. It is advised to mostly use Fake Out at the beginning of the battle even against Non-Sturdy Pokemon and Dragonite to get additional damage which in turn helps it in letting it KO other Pokemon with ease and by not being too reliant on damage rolls. However, avoid using Fake Out against Pokemon like Garchomp as the Rough Skin residual damage may prove to be a fatal mistake and will put it in range of one of Garchomp's attacks. Use hydro cannon with caution against faster Pokemon such as Mega Charizard X, Landorus-T, and Mega Pinsir as they may use substitute to block the move and proceed to KO it with one of their moves so predict accordingly and use Hydro Cannon at the appropriate turn. You may also consider not using Fake Out in certain matchups to bluff running counter which will make your opponent think twice about clicking their attacks.
Allies such as donphan, golem and landorus will benefit blastoise grealtly because they threaten strong electric based attackers. Allies with speed control such as Mega Blaziken, Mega Pinsir, and Magnezone can patch up for Mega Blastoise's lackluster speed and are able to beat Mimikyu and Jumpluff which beats blastoise. Pokemon that beat Mega Charizard Y such as Tapu Koko, Tapu Fini and Nihiligo would also be a big help as Mega Charizard Y has the ability Drought which lowers the effectiveness of your strongest hitting move Hydro Cannon and Drought also gives MegaCharizard Y a one turn Solar Beam which easily 2HKOs or OHKOs Mega Blastoise. Pokemon like Charizard appreciate Mega Blastoise beating Mega Lopunny, Mega Pinsir, and Sturdy Pokemon
Aqua Jet would be a good option especially if the atrack you went for didn't ko the opponent aqua jet can be used to pick off the severely damaged foe. Counter would be helpful against strong and bulky physical attackers such as bulkier variants of Kyurem-Black which does not get KOed by Dragon Pulse, but for Counter you will have to sacrifice Fake Out. Mirror coat could also be used to great effect against Pokemon like Mega Charizard Y which are bulky enough to take any of Blastoise's attacks. Icy wind with 92 speed EVs would also be an alternative option for sturdy users as icy wind lowers your opponents speed which then allows you to invest in more bulk allowing you to survive stronger hits. This would also make the Landorus-T match up completely on Mega Blastoise's side as it does not have to risk Hydro Cannons being blocked by Substitute. Furthermore and most importantly it also helps Mega Blastoise by serving as a speed control move against Pokemon like Mimikyu which could Curse and stall woth Protect and Substitute otherwise.
