ORAS OU Volcarona centered Team

[godzillasthunderthighs]

Hey everyone! This is my first time putting a team on here so please forgive my inexperience! Anyway I wanted to put together a team based on Volcarona being my favorite Pokemon. This team has done pretty well so far on Showdown but I'd still like some feedback on how I could make this team for effective.

Amaterasu/Volcarona @ Lum Berry
Ability: Flame Body
EVs: 72 HP / 252 SpAtk / 184 Spe
Timid Nature
-Fire Blast
-Bug Buzz
-Giga Drain
-Quiver Dance

The star and main sweeper of the team. 72 HP EVs for the little extra bulk to safely set up Quiver Dance. Once it's got the boost it can cause major damage to the team as long as major checks like Talonflame and Heatran have been removed from play. Fire Blast and Bug Buzz are great STAB attacks and hit a lot of common types in OU very hard. Giga Drain is a great move to take out water types that may be hoping to stop Volcarona's sweep as well as provide some recovery. Lum Berry keeps Volcarona healthy during it's sweep from Prankster Thunderus and the likes.

Suijin/Starmie @ Life Orb
Ability: Analytic
EVs: 4 HP/ 252 SpAtk /252 Spe
Timid Nature
-Hydro Pump
-Psychic
-Ice Beam
-Rapid Spin

Starmie pairs extremely well with Volcarona with it's entry hazard removal as well as being able to take out Volcarona's threats. Starmie forces lots of switches which makes Analytic all the more useful with the damage boost really hurting whatever comes in. Timid nature lets it outspeed the likes of Gengar and Serperior who would normally cause it a lot of problems. Hydro Pump hurts Heatran and Ground/Rock types that could cause Volcarona trouble. Ice Beam takes out Dragon types that would also wall Volcarona.

Godzilla/Tyranitar @ Smooth Rock
Ability: Sand Stream
EVs: 248 HP / 80 Def / 180 SpDef
Impish Nature
-Stealth Rock
-Stone Edge
-Pursuit
-Crunch

Tyranitar is my answer to Talonflame being able to tank it's most common attacks, particularly Galewing Brave Bird which stops Volcarona dead in it's tracks. Stealth Rock of course is very nice for fending off Talonflame and Mega Charizard Y as well as breaking Focus Sash with Stone Edge to finish them off. Pursuit helps take out Latias and Latios who may want to Defog and Crunch is a nice STAB to have on hand.

Sarutahiko/Excadrill @ Life Orb
Ability: Sand Rush
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
-Earthquake
-Iron Head
-Rock Slide
-Rapid Spin

Excadrill is here to take advantage of Tyranitar's Sand Stream and be the second sweeper of the team. Under sand Excadrill can outspeed almost everything unboosted and hit extremely hard. Earthquake hurts a ton of threats and Iron Head 1hKOs practically all Fairy types while Rock Slide takes out Flying types. Rapid Spin takes the fourth slot just for the extra entry hazard removal for Volcarona.

Tsukiyomi/Clefable @ Life Orb
Ability: Magic Guard
EVs: 252 HP / 252 SpAtk / 4SpDef
Modest Nature
-Moonblast
-Fire Blast
-Focus Blast
-Soft-Boiled

I really like this Clefable set! The maxed out HP lets it tank a lot of neutral attacks and the SPAtk and Modest nature let it hit as hard as possible. Moonblast is a very nice STAB move and Fire Blast is great when Steel types are lured in and Focus Blast when that Steel type happens to be Heatran. Soft Boiled is good for recovery so Clefable can continue tanking and wearing down threats.

Daikoku/Sableye-Mega @ Sablenite
Ability: Prankster/Magic Bounce
EVs: 252 HP / 112 Def / 144 SpDef
Careful Nature
-Knock Off
-Will O Wisp
-Taunt
-Recover

Sableye is fantastic being useful both before and after Mega Evolving! With Prankster I can shut down potential sweepers with Taunt and cripple physical attacks with burn. After Mega Evolving I can put a complete halt to setting up hazards or status effects as well as being a very nice wall with Recover and Knock Off to shut down item reliant enemies.

Greetings, and welcome! I also really love Volcarona, it is my second favorite fire type (Arcanine) and I'm happy to see you using him/her. This might just be a personal preference, but I would run Fiery Dance>Fire Blast. Fiery Dance has a broken 50℅ chance of raising your special attack stat another stage, which IMO makes up for the loss of BP. Furthermore, Fire Blast misses. And as I know very well (I was one of those assholes that spammed Volc in BW) a miss can spell the end of a Volcarona sweep.
Moving on from Volcarona, I see that you have two separate spinners and a bouncer on your team. I understand why that could be useful, like if one was knocked out or had a bad match up against the hazard setter, but I personally find it to be redundant, and also a loss in opportunity. So, I think you should run a bulky Utility Starmie.

Starmie
@ Leftovers
Natural Cure
Timid Nature
252 HP/4 SpAtk/252 Spe
Scald
Rapid Spin
Recover
Psyschock/Reflect Type

You don't get the flashy offensive prowess of the Analytic set, but you have a much more reliable spinner. Scald gives you a good shot to burn switch-ins that may try and pursuit trap you and end your life. Furthermore, reflect type stops that shit cold. You can use Psyschock to get a better match up against Amoonguss and co. And also fighting types, but whatever.
If you make that change, then you don't need RS on Excadrill anymore, and you can now run possibly the most dangerous Pokémon in the game. That being SD Excadrill. This badger mole thing can be the end of any team. With air balloon, you can switch in on obvious Earthquakes to your TTar by Lando-T's and whatever else might be EQing your shit up. Then, they are forced to hit you with a less preferable attack to pop your balloon. Use this move to set up SD. THEN SWEEP. Anyhow, here is the set.

Excadrill
Air Balloon
Sand Rush
Adament
252 Atk/4 Def/252 Spe
Earthquake
Iron Head
Rock Slide
Swords Dance

Also, small nitpick, but I think you should have Low Sweep>Crunch on TTar. It gives you the ability to fuck Heatran and stuff. Now on to the Clefable set. You're missing out on some opportunity. Focus Blast, honestly, is a bad option for Clef. Its only utility is to beat a weakened non specially defensive Heatran? That's no bueno. He will outspeed, and will at least 2HKO. Instead, just run Thunder Wave. It has infinitely more utility on Clef, and it still cripples Heatran, allowing you to outspeed Heatran with TTar and OHKO with Low Kick. Please consider this, because Focus Blast is on Clefable is a crazy unreliable answer to Clefable.
Now onto Sableye. Sableye isn't really in my style of Pokemon, so I wouldn't have used him, but I think he is a good idea. A nice alternate form of hazard control. This is nice utility, but I think you have a sweet opportunity to add another win condition to your team if you change the set.

Sableye-Mega
@Sableyenite
Prankster
252 HP/252 Def/4 SpDef
Will o' Wisp
Shadow Ball
Calm Mind
Recover

This set is rarely prepared for, so it can be devastating to many teams that lack a strong enough physical attacker to not only break 2HKO, but also do this whilst not minding a burn. If you can keep stealth rock on their side of the field, you can weaken any fire types like MegaZard X and whatever. This should be easy, because you have a reliable stealth rocker and a way to beat almost any defogger/rapid spinner. If the opposing team is weakened and the main wall to this set is gone or crippled, then Sableye sweeps. I think that these are the changes you need to make to turn this okay team into a really good team. I hope you will consider them.

 

[godzillasthunderthighs]

Alright so I tested out some of the changes you recommended and here's what I've come up with.

Swords Dance Excadrill is fantastic and can be extremely devastating so I'm definitely keeping it on my team. I also love the new Mega Sableye set and the bulkier Starmie has been very useful.

Now what I'm wondering is if there's some possible alternative to Low Kick on TTar because as it stands with the EV set up I've got on him it just doesn't have the power to 1HKO Heatran and doesn't do nearly as much as I'd like against Chansey. I've been considering Superpower but I feel like the stat decrease would be too counter productive on TTar so maybe a different EV spread is in order.

Also with Starmie going bulk I'm worried about losing Ice coverage to take out potential walls to my team like Garchomp or Gliscor. Been considering maybe putting Ice Beam on Clefable.

Finally my reasoning for using Fire Blast over Fiery Dance is while the boosts from Fiery Dance is fantastic it just doesn't have the raw power to 1HKO the likes of Lando-T and other such potential dangers. The accuracy has been an issue however so maybe I'll do some more tests.
