Hi. Before I get into the team rate, I need to address a couple of things.
It seems like your strategy is to use Pokemon in a certain team order. Unfortunately, this strategy doesn't work since opponents can switch Pokemon, meaning your Pokemon will struggle. :( If you want to win more battles, you shouldn't use Pokemon in a set order. You should also switch out if a Pokemon of yours is up against a threat/check.
Half of the Pokemon on your team don't have much viability, if any, at all. The Pokemon are Shuckle, Ribombee, and Orbeetle. The other Pokemon just need changes in their movesets.
Team Rate
Here are the changes I made:
Shuckle -> Araquanid
Araquanid @ Heavy-Duty Boots
Ability: Water Bubble
EVs: 248 HP / 8 Atk / 252 SpD
Careful Nature
- Liquidation
- Leech Life
- Toxic
- Mirror Coat / Scald
Shuckle isn't that good on Bug teams. Shuckle is outclassed as a lead. I know Shuckle had Stealth Rock, but Stealth Rock isn't really needed on bug teams. I replaced Shuckle with Araquanid since Araquanid's special bulk alongside Water Bubble allow it to check Fire-types such as Heatran and Blacephalon. Mirror Coat is used to chip strong special wallbreakers. Scald can be used if you feel like fishing for burns.
Scizor
Scizor @ Metal Coat
Ability: Technician
EVs: 40 HP / 252 Atk / 216 Spe
Adamant Nature
- Swords Dance
- Bullet Punch
- Knock Off
- Roost
Scizor doesn't have Adaptability, but it does have Technician. Starf Berry is too niche of an item for Scizor to use, so I replaced it with the standard item Scizor uses, Metal Coat. Metal Coat is used to boost Scizor's Bullet Punch without drawbacks. The speed EVs allow Scizor to outspeed Jolly Azumarill. Knock Off is used over X-Scissor, as Knock Off is useful to make progress vs Pokemon such as Ferrothorn, Aegislash, and Toxapex.
Ribombee -> Galvantula
Galvantula @ Focus Sash
Ability: Compound Eyes
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Sticky Web
- Thunder
- Energy Ball
- Volt Switch / Bug Buzz
Ribombee is also not good on Bug teams. As a Sticky Web setter, Ribombee is outclassed by Araquanid and Galvantula. Unlike Ribombee, Galvantula can threaten Flying-types. Since both of the mentioned Pokemon will be on the team, Galvantula is the Sticky Web setter. Speaking of Sticky Web, you ideally want to setup Sticky Web as soon as possible, rather than waiting until sending out your 3rd Pokemon to use Sticky Web. Focus Sash is there to guarantee you get Sticky Web up.
Buzzwole
Buzzwole @ Choice Scarf
Ability: Beast Boost
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Close Combat
- Ice Punch
- Earthquake
- Leech Life
Changed the Buzzwole set from a Bulk Up set to a Choice Scarf set. This set provides your team with speed control alongside Sticky Web.
Volcarona
Volcarona @ Heavy-Duty Boots
Ability: Flame Body
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Quiver Dance
- Flamethrower / Fiery Dance
- Psychic
- Giga Drain
Volcarona is used as a Quiver Dance Sweeper, so it has no business running Defog. Bug teams don't need Defog support because most Stealth Rock weak Bug-types wear Heavy-Duty Boots. Other Bug-types such as Scizor and Buzzwole take neutral damage from Stealth Rock. (Defog also gets rid of the Sticky Web you setup.) You can still use Fiery Dance, although Flamethrower is more consistent. Volcarona also doesn't really need Bug STAB. Psychic lets Volcarona hit Toxapex. Giga Drain lets Volcarona do super effective damage to Ground-types like Hippowdon, Swampert, Gastrodon, and Seismitoad.
Orbeetle -> Heracross
Heracross @ Flame Orb
Ability: Guts
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly / Adamant Nature
- Swords Dance
- Close Combat
- Facade
- Knock Off
I know you had Orbeetle as a special attacker, but Orbeetle isn't good on Bug teams. I changed it to Heracross, as Guts Heracross allows you to break through bulky Pokemon such as Toxapex and Galarian Weezing. This makes Heracross an important Pokemon on Bug teams. Jolly Nature gives Heracross more speed, while Adamant lets Heracross hit harder. If you still want a special attacker and still have Heracross, I have a couple of options.
Both of the options require making Araquanid the Sticky Web setter, so here's the Sticky Web Araquanid set:
Araquanid @ Heavy-Duty Boots
Ability: Water Bubble
EVs: 252 HP / 100 Atk / 156 Spe
Adamant Nature
- Sticky Web
- Liquidation
- Mirror Coat
- Toxic / Magic Coat
Option 1: Since Araquanid can be a Sticky Web setter, replace Galvantula with Vikavolt. Vikavolt is a more bulky and stronger version of Galvantula that can last longer. Here is the Vikavolt set:
Vikavolt @ Heavy-Duty Boots
Ability: Levitate
EVs: 252 HP / 172 SpA / 84 Spe
Modest Nature
IVs: 0 Atk
- Thunderbolt
- Energy Ball
- Toxic
- Roost
Toxic is useful against any Pokemon who resist Electric- and Grass-type moves, as well as Pokemon such as Dragonite and Landorus-Therian, who can get crippled by the poison. 252 HP EVs is for bulk, while 84 Speed EVs lets Vikavolt outspeed -Speed Celesteela.
Option 2: Use a Choice Specs Galvantula set. Here is the set:
Galvantula @ Choice Specs
Ability: Compound Eyes
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Thunder
- Bug Buzz
- Energy Ball
- Volt Switch
Here are the final versions of the team:
Webs Galvantula
Bug with Vikavolt
Specs Galvantula
Don't forget my advice about not using Pokemon in a set order. Hope these changes help! :)
