Diancie-Mega @ Diancite
Ability: Magic Bounce
EVs: 208 Atk / 48 SpA / 252 Spe
Hasty Nature
- Diamond Storm
- Moonblast
- Earth Power
- Protect
Building around Volcarona, I decided to use a Mega Diancie + Volcarona core due to their offensive synergy, with Diancie beating Rock-types and Flying-types for Volc and Volc beating Grass-types and Steel-types for Diancie.
Standard moveset and EV spread, with Hasty to avoid Heatran and Kyu-B having a chance to OHKO with Earth Power from full if using Naive.
Volcarona @ Charcoal
Ability: Flame Body
EVs: 140 Def / 172 SpA / 196 Spe
Modest Nature
IVs: 0 Atk
- Fire Blast
- Giga Drain
- Quiver Dance
- Protect
QD Volc is a cool mon, and works extremely well if you can remove priority users, which this team attempts to do. Charcoal, Fire Blast, and this much Special Attack investment let it OHKO Aegislash and Amoonguss at +0, and gets around Wide Guard, in turn supporting Diancie - you can bump up to 200 if you want to OHKO Kang at +1. Giga Drain gives Volc some recovery, and means that boosted up it can hit would-be checks such as Rock-types and Water-types.
Speed outspeeds Adamant Scarf Lando-T at +1, and Hoopa at +0, with leftover EVs dumped into Defence.
Amoonguss @ Sitrus Berry
Ability: Regenerator
EVs: 252 HP / 184 Def / 72 SpD
Relaxed Nature
IVs: 0 Atk / 0 Spe
- Rage Powder
- Spore
- Giga Drain
- Protect
Amoonguss gives us a much needed Keldeo and Rotom-W counter, while also providing redirection, Spore, and a TR check. Standard spread, not much else that needs explaining.
Rotom-Wash @ Sitrus Berry
Ability: Levitate
EVs: 252 HP / 32 Def / 104 SpA / 96 SpD / 24 Spe
Modest Nature
IVs: 0 Atk
- Thunderbolt
- Hydro Pump
- Will-O-Wisp
- Protect
Rotom-W finishes a FWG core, gives a Ground immunity, and provides Burn support for Volcarona's frailer side. Rotom-W further helps against Talonflame, and counters Heatran, which is extremely threatening to the team at this point. Bulky spread, think it OHKOes Talon with T-bolt and special bulk maybe does something, with EVs to outspeed Scarf Lando under Tailwind.
Talonflame @ Life Orb
Ability: Gale Wings
EVs: 136 Atk / 120 SpA / 252 Spe
Naughty Nature
- Brave Bird
- Overheat
- Tailwind
- Protect
Priority is something I believe all good teams should have, but more than that Talonflame threaten things such as Rain and TR with a strong BB. Overheat so that we can kill scary Mega Metagrosses even if intimidated, and means no King's Shield mindgames (less recoil is always nice as well). Tailwind can be clutch in supporting other team members against fast offensive team, but I am highly considering Taunt instead to stop TR and Heatran Subs.
Kyurem-Black @ Leftovers
Ability: Teravolt
EVs: 20 HP / 252 SpA / 236 Spe
Modest Nature
IVs: 0 Atk
- Ice Beam
- Earth Power
- Substitute
- Protect
Still feeling a bit weak to Heatran, Kyurem-Black became the final member of the team. It also helps against Skymin and is just hard hitting in general. Kyu-B can also threaten Thundy and Amoon, which can be problems at times. Baiting Keldeo out gets the chip damage required for Volc to KO at +1 with Giga Drain.
With the addition of Hoopa to the metagame, outspeeding it is an important benchmark, and with Kyu-B opponents will tunnel vision on hitting through Subs and Protect that they forget that you may be faster.
