[SET COMMENTS]
<p>This set may seem confusing to some people who
are lacking in lack imagination. While it may seem very strange to stick Volcarona, a Fire-type, on a rain team
(semicolon)(comma) however(comma) if you look outside the box, then it would slowly become apparent that Volcarona fits
on a rain team like a ligand
fits on a receptor. The main attraction of this set is that Volcarona checks many Pokemon that threaten Drizzle teams, such as Celebi, Calm Mind Virizion, Toxicroak, Latias, Ferrothorn, and Scizor. It also gives
such rain teams a huge weapon to use against Drought teams, since Volcarona is ridiculously powerful in the sun. The main thing to remember
about this set is that while
Drizzle Volcarona can often sweep, its primary objective is to support the team by checking the aforementioned threats
to rain teams(period) while looking for an opportunity to sweep.</p>
<p>Bug Buzz is now Volcarona's main STAB attack, and it
still hits very hard after a Quiver Dance.
Now that Volcarona is operating in rainy weather, Hurricane is now a very viable option as a powerful move. In the rain, Hurricane is a viable option for Volcarona(period) With
Hurricane(comma) it, Volcarona can now OHKO Choice Band Dragonite after Stealth Rock damage about 50% of the time
as well as hitting and hit Terrakion extremely hard. Defensive Dragonite cannot OHKO Volcarona with anything apart from Aqua Tail,
which means while Volcarona can easily 2HKO in return. While it may seems counter intuitive to use Fire Blast in the rain, it is still Volcarona's most powerful option against Ferrothorn, Scizor, and other Steel-types, such as Skarmory and Jirachi. Fire Blast cleanly OHKOs Ferrothorn, Skarmory and Scizor after Stealth Rock damage
while putting and puts a huge molten dent in Jirachi
even in the rain. It also becomes Volcarona's main weapon against a sun team. However, Substitute is another option for Volcarona
the to avoid status and Leech Seed from Pokemon like Jirachi and Ferrothorn, respectively.</p>
[ADDITIONAL COMMENTS]
<p>Although Volcarona
is playing plays a more supportive role, its EVs are still used to maximize sweeping potential, since there is little other reason to run anything else. A Modest nature is preferred for a chance to OHKO Ferrothorn with Fire Blast without a Quiver Dance. Since Volcarona is mostly playing
the a support role, Leftovers is the preferred item to increase Volcarona's longevity. However, Life Orb can be used to guarantee some very useful OHKOs, such as against Dragonite, Terrakion, Gliscor and Landorus after a Quiver Dance and Stealth Rock damage, as well as Jirachi after Spikes damage. It also guarantees an OHKO on Ferrothorn without a Quiver Dance.
Okay you definately need to specify what moves score these KOs, be it HP Water, Hurricane, or Fire Blast. Hidden Power Water can be used over Fire Blast or Substitute to heavily damage Heatran, but since Drizzle teams have very little trouble against Heatran,
so the options presented are better.</p>
<p>Like all the other sets, Stealth Rock, Blissey, Chansey, and Specially Defensive Heatran with Toxic and Roar are huge thorns in Volcarona's side. Although rare, Snorlax and Empoleon also handily
beats beat the fiery moth in the rain. Choice Scarf Landorus and Terrakion outspeed Volcarona even after one Quiver Dance and OHKOs with Stone Edge. Tentacruel and Starmie are excellent Rapid Spinners to use in the rain. Toxicroak switches into Blissey and Chansey with impunity and gets
extra HP recovery in the rain. Terrakion and Lucario also take down the two pink blobs
out extremely quickly. Dugtrio can trap and KO Heatran, as well as
removing remove other weather inducers, namely Tyranitar and Ninetales. Bulkier Grass-types such as Virizion and Tangrowth can take
on Landorus, while Latios is immune to Earthquake and easily OHKOs
it Landorus with Surf. Politoed is an essential teammate due to its ability to summon rain. Volcarona also appreciates entry hazards, especially Stealth Rock, as without it, it cannot scratch Multiscale Dragonite, who would KO in return.</p>
