& - A Sun Team
Introduction Ah yes, sun teams, you can do a lot of useful sweeps with these bois and help take care of your weaknesses, but this is a special themed sun team, because it has an actual song: &! It's one of my favorite songs alongside The Ultimate Showdown of Ultimate Destiny and Ruler of Everything. Hell, Tally Hall's songs are BANGERS!!! Let's not discuss song-related crap tho, as we're gonna get into the team.
Team-Building Process 
First up is our obvious Drought user, Torkoal! It'll also be the main Stealth Rock user, with a bulky defense, but poor speed, which means it can be taken out easily.
Next up is our obvious special sweepers, Venusaur and Charizard. I'm keeping two of these because when one faints, you can switch in for the other (but it has a lower priority because you can just use one.)
Here comes Indeedee, our Psychic Terrain setter... I wanted to use this instead of the obvious Volc because we were already weak to water, and you can do BIG damage with Expanding Force. Indeedee is underrated. (maybe not)
Bisharp is our physical attacker because you can run Swords Dance with it, even though it has no Fire-type moves. Use this as your finishing blow!
I needed a Defogger and momentum, so Corviknight was my choice. It is an obvious defogger in most teams you'd find here, plus you can give it U-Turn for some really easy momentum.
The Team! Tortoise (Torkoal) @ Heat Rock
Ability: Drought
EVs: 252 HP / 252 Def / 4 Spe
Bold Nature
IVs: 0 Atk
- Rest
- Sleep Talk
- Lava Plume
- Stealth Rock
My Drought user was Torkoal because it's actually pretty common. If you use this and use Stealth Rock, the Charizard in this team could guarantee an OHKO against Lando-T. You can click Lava Plume for the sweet sweet damage, however it's probably not needed because one of your other party members (for example, Charizard) could take down a lot of threats, like Clefable:
252+ SpA Charizard Overheat vs. 252 HP / 4 SpD Clefable: 225-265 (57.1 - 67.2%) -- guaranteed 2HKO after Leftovers recovery
252+ SpA Charizard Overheat vs. 252 HP / 4 SpD Clefable: 225-265 (57.1 - 67.2%) -- guaranteed 2HKO
252+ SpA Charizard Overheat vs. 252 HP / 4 SpD Clefable: 225-265 (57.1 - 67.2%) -- guaranteed 2HKO
Solarist (Venusaur) @ Life Orb
Ability: Chlorophyll
EVs: 252 HP / 252 SpA / 4 Spe
Modest Nature
IVs: 0 Atk
- Solar Beam
- Growth
- Weather Ball
- Reflect
Special Sweeper Venusaur set that relies on using Growth + Solar Beam/Weather Ball to OHKO/2HKO most mons, such as Lando-T, Rillaboom if you set up sun, Dragapult, and a few more to count. You can predict if Toxic's coming and switch in for this once you set up sun with Torkoal, but generally you are most likely guarenteed to face your fears with this. The reason why you're running Reflect is because of this team's weak physical defense (3/6 mons in this team have a bit of a... poor defense.)
Powered (Charizard) @ Leftovers
Ability: Solar Power
EVs: 4 HP / 252 SpA / 252 Spe
Rash Nature
IVs: 0 Atk
- Roost
- Overheat
- Tailwind
- Flamethrower
Here's our mighty boi! It doesn't matter if you are trying to get guaranteed OHKOs, or just Overheat in the face, this Charizard can do it all. This is meant to serve as one of the major wallbreakers, so don't get cocky. This thing can OHKO Clef in the right circumstances and also 2HKO Blissey. If a defensive mon ever comes, you can just use Charizard to serve as your killer. Keep this in mind, you can also OHKO Lando-T.
Eldritch (Indeedee-F) (F) @ Terrain Extender
Ability: Psychic Surge
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Mystical Fire
- Expanding Force
- Calm Mind
- Healing Wish
The reason why I used Indeedee over any other Fire-type mon is because of Expanding Force. Terrain Extender allows you to keep this up, and with Mystical Fire and Expanding Force, this is no exception. This allows you to 2HKO Choice Banded Dragapult and Ferro. Making no mistakes, you are wanting to use this as another Special Sweeper, just in case Charizard faints. It's worth it ;)
Crusher (Bisharp) @ Life Orb
Ability: Defiant
EVs: 252 Atk / 252 Def / 4 Spe
Adamant Nature
- Swords Dance
- Knock Off
- Iron Head
- Stone Edge
Physical Attacker time! This mon allows you to counter Corviknight due to it being a useful Defogger and momentum user. If you're lucky, you are guarenteed to 2HKO it if you can. Again, it can 2HKO Lando-T and Toxapex, so you are definetly gonna have to use this as your main physical sweeper. Yes, Sucker Punch is a bit more viable, but you could also use this for wallbreaking purposes.
Bird Up (Corviknight) @ Leftovers
Ability: Pressure
EVs: 252 Atk / 252 Def / 4 Spe
Impish Nature
- Defog
- Roost
- U-turn
- Body Press
Our momentum and Defogger, Corviknight allows you to easily target Lele and switch in for something else that could kill it. If you get into the hands of something like Shuckle, Defog it. You could also Body Press for that extra damage as well, so you can still use this for helping out on sweeping. You can use this as a supporter, but you also can use momentum to help you get some extra damage.
...And that's the team. I plan to edit this post with a threatlist, but I'm a lazy idiot, and plus, that would take a lot of game analyzing. Hopefully this team can be rated!
having a worse typing and worse stats overall. Even Tapu Lele doesn’t seems to be a great choice here and thus I think that both Bisharp and Indeedee can be replaced by more useful Pokemon in this team (but I’ll take about this latter).
with an extremely powerful Eruption, Kartana 
to threaten Fire resists and maybe use Solar Blade, Victini 
with an almost impossible to wall V-Create, and Volcarona 
which receive a precious boost for its Fire moves and can act as a setup sweeper and a wincon similarly to Venusaur. Thus, I’ll try to give you several options in some slots and I advise you to try different combination to see what works best for you. Keep in mind that some options are not better than others overall but are just more helpful in some Matchup and worse in others.
Indeedee doesn’t have much utility here. Healing Wish could be a good support move but Indeedee is both too frail and not fast enough to use it properly. I think that you should replace him with a Special Defensive Pivot to complete your Physical Defensive duo with Torkoal and Corviknight and deal with threats like Dragapult for instance. Blissey 
by giving them a choice item. As for Kartana, you can use the classic Banded set with 4 moves to maximize its coverage. These moves usually are Sacred sword, Knock Off, Smart Strike and Leaf Blade. You can consider playing Solar Blade instead of Leaf Blade to maximize your damage output under Sun, but you will basically lose your Grass STAB when Sun is not up. Here are the sets I described for both:
as otherwise it can come freely and Torkoal to remove your Sun, as well as making Torkoal less passive overall. Yawn is also an option here to have one free turn to safely switch-in one of your Sun abusers, but I feel that Body Press is a bit more useful. Lastly, your EV spread is fine except that you want to have 248 EVs in HP. This is because having an odd number of HP allows you to switch-in into Rocks one more time and as you will take 25% of your health and so it can quickly become helpful. Thus, here is the set you could use:
so keep it healthy against them. One thing you should change here however is the spread. You don’t need to have Attack EVs because as it is a defensive pivot you rather have more defensive investment. You should thus move this investment in HP. I give you a set you can use just bellow with the Smogon spread. A min Speed nature is here to give a Slow U-Turn so that you can switch in your breakers more safely. Keep in mind that the team remains overall somehow weak to Garchomp 
. You could try an Iron Defense, Body Press variant on Corviknight to tackle that issue, but losing Defog or U-Turn is a huge cost that harms Corviknight role of Hazard remover and Pivot.
