Mega Sableye is an extremely good Pokémon as we all know, providing in only one slot a ton of things to a team. And Volcarona, already a good Pokemon, becomes even better when paired to Mega Sableye and the things it provides.
- Although obvious, Mega Sableye makes Stealth Rock way harder to set up on the field, and Volcarona greatly appreciates it as it is quad weak to it. Protip, when you lead off with Sableye and the opponent does with rocker Garchomp, don't mega evolve and go straight for Will-o-Wisp, because they are often Lum Berry and try to get up an SD the turn you mega evolve. At turn 2, go for Will-o-Wisp again but Mega Evolve at the same time. Even though SD Garchomp can be handled by Unaware Clefable in the back, it may be sometimes better to get the mega evolution off on Sableye as early as possible.
- Mega Sableye is weak to fairies, and Volcarona completely stops some of them, most notably Clefable, but also specs Sylveon. EVs can be managed so Mega Gardevoir cannot 2HKO Volcarona with any move she wants to go for, although Taunt is annoying and Volcarona can't really do much to Gardevoir barring scaring her out. Mega Diancie is a problem, be sure to have something for it in the back, such as sp.def Skarmory. Mega Altaria can be handled depending on his moveset.
- Volcarona also use the fairies quoted above to setup Quiver Dances. And truth be told, Volcarona is at this moment a fearsome sweeper, a lot of team aren't prepared for it. Once boosted, it can be really threatening and sometimes even unstoppable. It also acts as a win condition and also has utility throughout the entire match, and can use its ability to cripple U-Turn abusers or some Lopunnies who would've wanted to Fake Out Mega Sableye. They often do that in order to dodge the Will-o-Wisp during the turn Sableye is mega evolving.
- Knock Off on Mega Sableye removes Heatran's leftovers, which can in a long run really benefit to Volcarona, as Heatran is a big counter to this set.
- Toxic on Mega Sableye make Charizard Y and Stallbreaker Talonflame, both really annoying for Volcarona, less threatening. Mega Sableye overall walls Stallbreaker Talonflame all days and Toxic also allows it to beat the Bulk Up variants. And if you want my opinion, Toxic is one of the best move to use on Mega Sableye.
- : Tentacruel brings important Spin support to the core, but it is not chosen randomly. Indeed, the combination of Magic Bounce Mega Sableye + Rapid Spin Tentacruel makes your side of the field theorically nearly always clean without any kind of hazards. Mega Sableye beats a lot of SR users and Tentacruel deal with the others, which are Clefable, Empoleon, and Heatran. SR Mega Diancie, SR Mold Breaker Excadrill and SR Landorus-I are still issues though.
- : Chansey deals with Mega Charizard Y and Mega Diancie, and overall a shit ton of Pokémon. It's always a good Pokemon to have in Stall. Heal Bell Support is also important because a burned Mega Sableye isn't a happy Mega Sableye.
- : Clefable is another blob good along this core. It can get up rocks, wall Belly Drum Azumarill, DD Mega Altaria, SD Taunt-less Gliscor (which is a thing nowadays apparently), or act as a second win condition with Calm Mind although it is kinda redudant with Volcarona as they share the same counters. Ice Beam can catch those fucking Gliscor off guard if you're worried about them.
- : Ferrothorn is a check to Thundurus and an answer to Volt-Turn. It has overall a good utility, can get up spikes, and brings passive recovery to the team in the form of Leech Seed. It is also a nice check to fairies depending on their moveset (HP Fire-less Mega Diancie, for example). If holding a Shed Shell, you can switch out to Volcarona when facing a Magnezone, which will give you a free Quiver Dance.
- : Heatran is another check to fairies but also a much-needed check to Choice Banded Victini which destroys this core. A Balloon can potentially be used in order to also check Mega Charizard X. With Taunt and Magma Storm, it can also act as a nice stallbreaker.
- : Skarmory brings Defog Support, and with Counter, it can beat Bisharp which is a huge threat over there. Don't think Mega Sableye is enough to check Bisharp, because you often end up getting flinched. Skarmory is by the way an answer to Sand Offense. It can also get up Spikes. A sp.def set allows it to counter Mega Diancie reliably.
- : AV Tornadus-T adds a much-needed check to Landorus-I and Life Orb Taunt Gengar. It's a great way to gain momentum and adds to the team a lot of speed.

- Like I said above, you can go for 248/252+ on Volcarona's physical bulk in order to always dodge the 2HKO from Modest Mega Gardevoir's Psyshock. The 140 EVs in speed currently allow Volcarona to outspeed Mega Lopunny after 1 boost.
- EVs can be managed differently on Sableye as well, although the max HP/Def never disappointed me. 8 Spe EVs, just so you outspeed other Mega Sableyes and possibly finish them off, and you also don't risk a tie with Ferrothorns who only use Power Whip as their offensive move.
