Intro
I recently started playing RU back in ORAS, and just got back into it during SM. When Mega-Blastoise dropped down I was thrilled because finally Blastoise would be relevant again outside of It's normal form, which was sitting down at D Rank. I never really build teams but i felt like this one was good enough to be posted here and critiqued to make it even better. Without further ado, let's get into the team breakdown!
Building Process

Of course, I wanted to start off with Mega-Blastoise. I feel like this mon is great because it's able to provide sort of a glue to both Offensive, and Balanced teams. Being able to reliably remove hazards, and having no mons really switch into it due to its high Special Attack and Mega Launcher boosted attacks is big for this mon. Spinblockers in the tier like Doublade, get blown away by Dark Pulse on the switch. One of the few things that threaten it offensively are electrics like the Rotoms, and Galvantula, and grasses such as Shaymin.


Because of it's ability to reliably check common electrics in the tier that Blastoise struggles with, Nidoqueen was the premier choice of a Stealth Rocker, and Toxic Spiker for this team.



I added Snorlax because it's able to handle most of the Ice, and Fire types in the tier, Salazzle being a big one. While still providing offensive pressure.




Being one of the best spinblockers and defensive Pokemon in the tier, I added Doublade because it's an amazing defensive mon, and at the same time can pressure the opponent with its high Attack stat.





One of the most threatening mons in the RU metagame at the moment, I added Flygon because it provides a ground immunity, and appreciates the hazard support that Nidoqueen is able to provide.






Last but not least, I added Shaymin to the team because it's able to check mons like Mega-Steelix, and most bulky waters in the RU tier, while providing speed control.
Sets

Blastoise @

Ability: Rain Dish
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Scald
- Dark Pulse
- Aura Sphere
- Rapid Spin
-----------------------------------
The main mon on this team. Can reliably remove hazards and harm anything that wants to switch into it. Dark Pulse hits mons like Bronzong, Doublade, Necrozma, and other assorted Psychics that roam around the tier, Aura Sphere can scare mons like Porygon-2, Umbreon, and Snorlax dealing decent damage to them on the switch, Aura can also take a decent chunk out of Milotic, its main wall. This mon is essentially a glue to the team, synergizing well with Nidoqueen which is able to handle its checks like Galvantula, and the Rotoms.

Snorlax @

Ability: Thick Fat
Happiness: 0
EVs: 188 HP / 128 Def / 192 SpD
Careful Nature
- Curse
- Frustration
- Rest
- Earthquake
-----------------------------------
Snorlax, able to provide offensive pressure, and be an amazing Special Defensive wall if need be. This mon successfuly switches into mons like Salazzle, Galvantula, and Rotom. Using them as set up fodder and resting off any status they wanna spread to it. Frustation, being its main STAB move hits extremely hard on mons that take it Neutrally. Earthquake can OHKO Salazzle without having to curse and can hit mons like Nidoqueen but has to be weary of Focus Blast because it's able to pick up a 2HKO. Utilizing Thick Fat it's also able to check alot of Ice and Fire types in the tier, including Mega-Glalie.

Doublade @

Ability: No Guard
EVs: 252 HP / 180 Atk / 76 SpD
Adamant Nature
- Swords Dance
- Shadow Sneak
- Sacred Sword
- Shadow Claw / Iron Head
-----------------------------------
Doublade is my main physically defensive mon on the team. It's able to check mons like Snorlax, Bewear, Cloyster, can 2HKO Mega-Steelix at +2, and revenge kill Linoone if healthy enough. This mon is also an amazing spinblocker and switches in on things like Tsareena. This mon appreciates Shaymin as a teammate because it's able to take on milotic, which would otherwise wall it. It's also able to hurt Florges if I decide to carry Iron Head.

Shaymin @

Ability: Natural Cure
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Seed Flare
- Healing Wish
- Psychic
- Hidden Power [Ice]
-----------------------------------
Shaymin is a solid scarfer on this team because it's able to handle mons like Milotic, revenge Feraligatr even after a DD, hurt Chesnaught, and Salazzle with Psychic, revenge Flygon, Swellow, and Zygarde 10% w HP Ice after Rocks, and support the team with Healing Wish. I chose Shaymin as my scarfer because it sits at a solid Base 100 speed, revenge killing alot of mons in the current RU Metagame. Doublade appreciates the support Shaymin has to offer it by checking Milotic, as well as the rest of the team.

Nidoqueen @

Ability: Sheer Force
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Stealth Rock
- Earth Power
- Ice Beam
- Toxic Spikes
-----------------------------------
Nidoqueen is an amazing Stealth Rocker on this team. Along with Toxic Spikes, this mon is able to irritate milotic by forcing it to take residual and poison damage on the switch. Mons like Flygon love this because it can cripple most of the opponent's Pokemon. Being a good Offensive-Support Pokemon. With support from Shaymin it doesn't have to be weary of opposing Mega-Blastoise, and Milotic.

Flygon @

Ability: Levitate
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Dragon Dance
- Earthquake
- Outrage
- Iron Tail
-----------------------------------
Flygon is a solid setup sweeper in the current metagame. This mon is able to handle most Electric, Rock, and Fire type mons, and does huge damage with Z-Outrage, even hitting hard on a resisted hit. Levitate allows it to be a great ground immunity for the team, and Iron Tail enables it to hit Pokemon like Florges for Super Effective damage. It fits well because it appreciates Hazard Stack as it forces a lot of switches.
Threat list
Mandibuzz

This mon is a huge threat to the team, it hard walls 5/6 of the teams members outside of Nidoqueen which I'm forced to switch in on a potential Foul Play / Knock Off being worn down after a while. Once Nidoqueen falls, this mon is able to run rampant.
Necrozma

Photon Geyser is able to put huge dents into this team. Once my breakers for this mon fall, Special Necrozma is able to do massive damage to mons like Doublade, Nidoqueen, and Flygon if i haven't boosted rendering me unable to switch-in to it.
10% and opposing Flygon


Usually nothing likes switching into a Banded Zygarde 10% or boosted Flygon, and once Shaymin falls I barely have a way to reliably check these two mons.
Importable
