Volcarona @ Lum Berry
Ability: Flame Body
EVs: 248 HP / 208 Def / 52 Spe
Bold Nature
- Roost
- Bug Buzz
- Fire Blast
- Quiver Dance
This bulky set allows Volcarona to survive hits from the faster mons, while still outspeeding the slower, bulkier mons, such as Deoxys-Defense and Metagross
Volcarona can successfully set up on Meloetta, and then roost off all damage taken
252 SpA Choice Specs Meloetta Psychic vs. 248 HP / 0 SpD Volcarona: 210-247 (56.3 - 66.2%) -- guaranteed 2HKO
252 SpA Choice Specs Meloetta Psychic vs. +1 248 HP / 0 SpD Volcarona: 139-165 (37.2 - 44.2%) -- guaranteed 3HKO
Hoopa can only 2HKO, so as long as volc gets off one Quiver before it switches in, it can live, Quiver again, and outspeed and kill the subsequent turn.
252 Atk Hoopa Unbound Hyperspace Fury vs. 248 HP / 208+ Def Volcarona: 189-223 (50.6 - 59.7%) -- guaranteed 2HKO
Lum Berry helps avoid getting residual right away from Deoxys, essentially providing one free Quiver Dance
Once Volcarona gets to Plus 2, it sweeps the whole team:
+2 0 SpA Volcarona Bug Buzz vs. 0 HP / 4 SpD Meloetta: 404-476 (118.4 - 139.5%) -- guaranteed OHKO
+2 0 SpA Volcarona Bug Buzz vs. 0 HP / 0 SpD Hoopa Unbound: 804-948 (267.1 - 314.9%) -- guaranteed OHKO
+2 0 SpA Volcarona Fire Blast vs. 252 HP / 96 SpD Assault Vest Metagross: 404-476 (110.9 - 130.7%) -- guaranteed OHKO
+2 0 SpA Volcarona Bug Buzz vs. 248 HP / 0 SpD Mega Latias: 354-416 (97.5 - 114.6%) -- 81.3% chance to OHKO
+2 0 SpA Volcarona Bug Buzz vs. 0 HP / 4 SpD Mew: 500-590 (146.6 - 173%) -- guaranteed OHKO
+2 0 SpA Volcarona Bug Buzz vs. 248 HP / 8 SpD Deoxys-D: 332-392 (109.5 - 129.3%) -- guaranteed OHKO
Darmanitan @ Life Orb
Ability: Sheer Force
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Filler
- Filler
- U-turn
- Flare Blitz
The man point of Darmanitan is to lure in the bulkier members, such as Mega Latias and Deoxys-Defense, and then U-Turn out into Volcarona to set up and sweep. However, if need be, Darmanitan can do some heavy hitting itself:
252 Atk Life Orb Sheer Force Darmanitan Flare Blitz vs. 248 HP / 252+ Def Deoxys-D: 179-212 (59 - 69.9%) -- guaranteed 2HKO after Leftovers recovery
252 Atk Life Orb Darmanitan U-turn vs. 248 HP / 68 Def Mega Latias: 172-203 (47.3 - 55.9%) -- 76.2% chance to 2HKO
