[Overview]
<p>Victreebel has a very good Attack and Special Attack. It can hit hard, and destroy teams that aren't prepared for it. Although it is very slow without Sunny Day, and doesn't have good defenses, Victreebel is a force to be reckoned with in the lower tiers. It's one of the best Sunny Day sweepers available.</p>

<p>Once you get Sunny Day up, Victreebel becomes a very powerful Sweeper. SolarBeam is your main attack, which causes a lot of damage to Pokémon that don't resist it. Weather Ball is great on Victreebel and with Sunny Day active it becomes a very strong Fire-type move, killing Grass and Ice-type Pokémon. The best option for the last slot is Sleep Powder, because it allows you to incapacitate your counter and set up Sunny Day easily. Hidden Power Ice is there because it kills Dragon-Type Pokémon that are resistant to Weather Ball and SolarBeam, although you won't find a lot of Dragons in NU (maybe Shelgon), so Hidden Power Ice works better in UU, to kill Altaria. In addition to covering the rare Dragon-type Pokémon, Hidden Power Ice covers Flying-type Pokémon too. Hidden Power Rock covers Fire-type Pokémon. You can also use Sludge Bomb in the last slot because of STAB, as it deals some powerful neutral damage to a lot of Pokémon that resist its other attacks.</p>
[ADDITIONAL COMMENTS]
<p>The EV spread lets him outspeed Electrode after setting up Sunny Day. You can also use 152 Evs in Speed to outspeed Choice Scarf Moltres, Adamant Rock Polish Torterra, Choice Scarf Rotom and Choice Scarf Timid Venusaur.</p>
<p>Life Orb gives Victreebel more power. With Life Orb, you will always OHKO Electrode with Solar Beam, and almost always 2HKO Hypno after Stealth Rock damage.</p>
<p>Choice Scarf Typhlosion outspeeds Victreebel and kills it with Eruption or Flamethrower. For that reason, Grumpig, Slowbro, Milotic and Slowking are very good team mates for Victreebel, as they can counter Typhlosion. Grumpig is an ideal counter to Typhlosion due to Thick Fat, which halves damage from Fire-type moves, and a high special defense, allowing Grumpig to take Typhlosion's STAB Eruption and Flamethrower and hit back with STAB Psychic. Milotic is also a good Typhlosion counter, being able to take any of Typhlosion's moves thanks to a Fire resistance and a monstrous base 125 special defense and OHKO back with STAB Surf. Slowking and Slowbro resists Typhlosion attacks very well too, thanks to their defenses and their Fire resistance, and they OHKO Typhlosion with STAB Surf.</p>

<p>Swords Dance Victreebel may seem to be outclassed by Leafeon, but that’s not true at all. Sleep Powder and Sucker Punch make Victreebell a different Pokémon. Use Swords Dance, and then proceed to attack. Leaf Blade is your main STAB attack, and it OHKOes a lot of Pokémon that doesn’t resist it after a Swords Dance. Sucker Punch is the strongest priority move in the game (tied with ExtremeSpeed), and it will do some decent damage to Pokémon that doesn’t resist it. The final Slot has a lot of options again. The best is Sleep Powder, as it allows you to set Swords Dance easily. Leaf Storm is a very strong special attack that can surprise your opponent, but Sleep Powder is generally the better option.</p>
[ADDITIONAL COMMENTS]
<p>The EV spread is simple. It maximizes Victreebel attack, and allows it to outrun base 60 Speed opponents. Put everything else into HP.</p>
<p>The item should be Life Orb, as it allows you to be more powerful. </p>
<p>Sunny Day support is very important in all Victreebel sets, as with it up, Victreebel will be much faster.</p>
<p>This set has problems against Steel-type Pokémon, so Dugtrio is a great team mate for Victreebel. With Arena Trap, STAB Earthquake and its great base 120 Speed, Dugtrio counters Pokémon such as Aggron and Registeel.</p>
<p>Arcanine can come in on Victreebel easily with Intimidate, and OHKO it with Flare Blitz. Swellow resists Leaf Blade, and can kill Victreebel with Brave Bird. For that reason, Pokémon like Slowbro and Registeel are good team mates for Victreebel. Slowbro's Defense is actually very good, and it lets him resist Arcanine attacks very well, and hit back with STAB Surf. Registeel is a great counter to Swellow because it is resistant to Swellow's STAB moves (and to Steel Wing) and can hit back with STAB Iron Head. </p>

<p>This Victreebel set can kill a lot of Pokémon that are not prepared for it, especially in OU. Leaf Blade is a great STAB Attack, and after a Swords Dance it OHKOs Milotic, Slowbro and Donphan, and almost always OHKOs Regirock in UU, and in OU it OHKOs Tyranitar, Hippowdon and Swampert and 2HKOs Blissey, defensive Rotom-A and Dusknoir. Sucker Punch destroys Alakazam, Espeon, Mismagius and Rotom in UU, and Gengar and Azelf in OU. It also gets priority, and can help when Sunny Day isn't up. Weather Ball is a good option as it is very powerful with Sunny Day, defeating a lot o Steel and Grass-type Pokémon . In OU, however, Hidden Power Fire is better, as Sandstorm is up in almost all battles due to Tyranitar and Hippowdon. It OHKOs Scizor, Forretress, and Lucario. It is also your best bet against Skarmory.</p>
[ADDITIONAL COMMENTS]
<p>As always, Sunny Day support is very important, Victreebel needs to be fast. A lot of UU Pokémon than can set up Sunny Day have been mentioned in other sets. If you are using Victorybel in OU, use Azelf, Uxie or Cresselia to set up Sunny Day (remember that in OU Tyranitar, Abomasnow and Hippowdon can stop Sunny Day with their abilities.)</p>
<p>The Evs maximize Victreebel Attack, and let it outspeed some Pokémon when Sunny Day is up. Life Orb is again the best choice.</p>
[Team Options]
<p>A lot of Pokémon can OHKO Victreebel, and most Pokémon are quicker than Victreebel. But, if Sunny Day is up, Victreebel outspeeds almost all Pokémon and can put his counters to sleep with Sleep Powder. That is why Sunny Day support is always fantastic. Probopass, Moltres, Meganium, Uxie, and Porygon2 are fantastic choices to use Sunny Day, as they can resist a lot of hits and then use Sunny Day. Moltres can use Sunny Day to sweep or to help its team mates. Meganium is bulky and can use Sunny Day very well. Uxie has fantastic defenses, and it almost always uses Sunny Day. Porygon2 can trace Flash Fire and then kill Arcanine and Houndoom. Porygon2 is also bulky and sets Sunny Day up pretty well.</p>
<p>As in all offensive Pokémon, Stealth Rock and Spikes support is fantastic. Probopass, Cloyster, Uxie, etc. can set Entry Hazards in your opponent team very well. Probopass' defenses lets it resist a lot of attacks and set up Stealth Rock. Uxie is also a great Support Pokémon, since it almost always sets up Stealth Rock, due to its high defenses.</p>
<p>For the Special Sets, taking out Clefable, Chansey, Umbreon and Regice can be very problematic, due to their high Special Defense. For that reason, Fighting-type Pokémon are great team mates for Victreebel. Hariyama, Hitmontop, Hitmonlee and Primeape are examples of Pokémon that cause problems to them, as their STAB Fighting-type moves hurt them a lot.</p>
<p>For the Physical Sets, it is very difficult to take out Leafeon, Muk, Aggron and Torkoal. For that reason, Water-Type Pokémon work well, as they take out Torkoal and Aggron, especially Gastrodon and Quagsire, as they can take out Muk very well with STAB Earthquake. Altaria is fantastic, because it takes out Muk, Aggron and Torkoal with Earthquake after a Dragon Dance, and resists Leafeon attacks.</p>
<p>When facing your best counter, Muk, you can at least put it to sleep and send out one of its counters (Drapion, Steelix, Bastiodon...) You can also set up a stat upper with ease, such as Rhyperior, Houndoom or Altaria in UU, and Crawdaunt, Armaldo or Tropius in NU. Aggron, Rhyperior (Rhydon in NU) and Golem are great team mates for Victreebel, as they kill Flying-type Pokémon, Ice-Types Pokémon and Fire-Type Pokémon with their STAB Rock-type attacks. They can also take out Muk, use Stealth Rock, and boost their Stats thanks to Victreebel Sleep Powder.</p>
<p>Flash Fire Pokémon, such as Arcanine and Houndoom, can come in a Fire-type attack, and proceed to attack.</p>
[Optional Changes]
<p>Victreebel movepool is actually very small. Teeter Dance and Toxic are good support moves. Growth can be used in a Special Sweeper Set. A Support Set, with Knock Off, and Sleep Powder can be used, but it's pretty outclassed by Venusaur. Synthesis is a good recovery move, but with Victreebel’s defenses, it won't ever really see a lot of use. Return, Double Edge and Body Slam are options for the Swords Dance Set. Stun Spore can be used in other sets as well, but it is generally inferior on sweeping sets. Reflect is a good support option, while Encore can be used to annoy other Pokémon. Gastro Acid and Worry Seed can mess with those who rely on their ability and Stockpile is an okay option too. You can try a SubSalac Set too, but it isn’t recommended. Choice Specs is an option, but it is outclassed by Sceptile and Venusaur.</p>
[Counters]
<p>Since Victreebel's defenses are very poor, a strong STAB attack almost always OHKOs or 2HKOs Victreebel. Arcanine, Typhlosion, Pidgeot, Dodrio, Fearow, Swellow, Altaria, Houndoom, Charizard, Magmortar, Hypno, Grumpig, etc, are good counters to Victreebel, because they take minimal damage from Victreebel’s hits and can hit him back with their STAB moves. Chansey and Mantine wall all the Special Attacks that Victreebel use, but Leaf Blade is dangerous for them. Muk is also a great option, as he resists both STAB moves, and can't be poisoned by Sludge Bomb. Also, Sticky Hold negates Knock Off.</p>
<p>In OU, Victorybell is walled by Skarmory, that can use Whirlwind or can OHKO it with Brave Bird, although he must be wary of Hidden Power Fire. Infernape can also be a problem, as he resists Sucker Punch, Leaf Blade and Hidden Power Fire. Dusknoir and Rotom-A can use Will-o-Wisp tu burn Victreebel. Some Choice Scarf users, such as Starmie, can outspeed Victreebel and kill it with their strong attacks. Abomasnow, Tyranitar, and Hippowdon can eliminate Sunny Day, but they won't like Victreebel's Hidden Power Fire (for Abomasnow) and Leaf Blade (for Hippowdon and Tyranitar).</p>
