Introduction:
Hello, Smogon! Welcome to my first OU team in Sun and Moon. This is a team that I've been having some success with so far, but there are definitely some issues that need to be worked out. This team was built around my favourite Mega that is currently available (besides Beedrill who was just released), Mega Metagross. MegaGross has been a beast pretty much since it was released in ORAS and it has done some serious work for me so far in SM, too. So, without further ado, let's dive in, shall we?
Teambuilding Process:

So, obviously I started with the Pokemon I built around, Mega Metagross. MegaGross is one of the premier wallbreakers in OU, and dishes out a ton of damage to the opposing team. Plus, it has a real nice typing of Steel/Psychic, allowing it to hit really hard.


Following MegaGross, I looked for a Pokemon that can serve to help dish out some damage and synergize well with him. Buzzwole fit the bill. Bug/Fighting gave me some more good coverage options, and Buzzwole's bulk and sky high attack stat lets it help out MegaGross a lot.




After the addition of Buzzwole, I looked for some defensive options. At first I tried the likes of Pelipper and Garchomp in those slots, but I didn't really like the way they synergized with the team. I eventually landed on Tapu Fini and Defensive Landorus-T. Tapu Fini provides the team with a very useful Fairy typing, a Defogger, and Misty Terrain to stop the burns that give this team all kinds of trouble. Landorus-T, on the other hand, provides Stealth Rock support and great Physical bulk, along with some momentum from U-Turn and the infamous EdgeQuake for some more coverage options.





Satisfied with my defensive pairings at this point, I looked to add some offense from the other side of the spectrum and add a special attacker or two. At first I looked at the likes of Tapu Koko or Ash-Greninja, and while they were powerful options, they didn't really seem to fit. It was here when I decided to give Magnezone a shot, and it has worked out wonders for the team. Magnezone provides some excellent offensive type coverage with Electric, a back-up plan for Fairy types should Mega Metagross go down, and not to mention its ability to trap and kill Steel types (especially Celesteela, which this team had trouble with), and it also provides a nice VoltTurn core with Landorus. All of these combined proved invaluable for the team.






So, with Magnezone added to the squad, the team was looking to be in good shape. All that was really lacking was a general attacker that could rain down the hurt on the opposing team. I considered some boosting sweepers here, such as Volcarona, Alolan Marowak or SD Garchomp, but instead settled on Latios. Latios was appealing to me for a number of reasons. It completed the team's Fairy-Dragon-Steel core, it hit from the Special side which my team still lacked, it gave another Ground immunity and it had great offensive typing. All in all, Latios rounded the squad out well, and here we are today.
The Team In-Depth:

Stone the Metagross@Metagrossite
Ability: Clear Body > Tough Claws
Jolly Nature
EVs: 252 Atk/4 Sp. D/252 Spe
-Meteor Mash
-Zen Headbutt
-Ice Punch
-Bullet Punch
Let's start things off with the core of the team. Mega Metagross is one of the premier wallbreakers in OU, and Stone is no exception. The set here is pretty standard and very straightforward. Meteor Mash is the go-to STAB move, hitting incredibly hard with the Tough Claws boost, STAB, and MegaGross' stupidly high Attack. Zen Headbutt is a nice secondary STAB option which also gets the Touch Claws boost and hits the likes of Buzzwole hard. Ice Punch is a great coverage move that lets Metagross threaten the likes of Garchomp, Salamence, and Gliscor. Finally, Bullet Punch gives Metagross a nice STAB priority option, that also gets the Tough Claws bonus.

Siren The Tapu Fini@Leftovers
Ability: Misty Surge
Calm Nature
EVs: 248 HP/192 Def/16. Sp. D/52 Spe
IVs: 0 Atk
-Taunt
-Nature's Madness
-Moonblast
-Defog
Next up, we have the first defensive Pokemon of the squad, Tapu Fini. Tapu Fini provides nice bulk and support options for the team, thanks to Misty Surge and Defog. Taunt is useful for stopping set-up sweepers, such as Alolan Marowak or Mega Alakazam, from setting up, and it is also useful in stopping a Pokemon from getting Stealth Rock up. Nature's Madness is an incredibly useful move, always doing half of the Pokemon's current HP, allowing Tapu Fini to help wear down threats the rest of the team might otherwise have trouble with. Moonblast is a nice STAB option that hits decently hard, and Defog keeps the field clear of hazards and lets the rest of the team switch in without having to worry about the hazard damage.

Magneto the Magnezone@Assault Vest
Ability: Magnet Pull
Modest Nature
EVs: 128 HP/252 Sp. A/128 Spe
IVs: 0 Atk
-Thunderbolt
-Flash Cannon
-Hidden Power [Fire]
-Volt Switch
Magnezone is a great Pokemon in the current metagame for its ability to trap and kill Steel types, and this Magnezone is no exception. Magnezone was brought in to help deal with the likes of Celesteela, Scizor (Mega or otherwise), and Ferrothorn, and it does its job well. Thunderbolt is the STAB move of choice here, providing the team with some valuable Electric coverage and hitting the aforementioned Celesteela hard, as well as helping deal with Water types such as opposing Tapu Fini or Ash-Greninja. Flash Cannon gives Magnezone a nice secondary STAB option and allows it to help deal with Fairies, such as the Tapus (especially Tapu Lele), or Mimikyu. Hidden Power Fire is the gem of the set, allowing Magnezone to take out trapped Ferrothorn, Scizor, or opposing Magnezone. Finally, Volt Switch gives the team some switch priority, which is always helpful for the team. I chose to run Assault Vest over Choice Specs due to it giving Magnezone the luxury of switching moves and more overall bulk, which helps it deal with opposing Magnezone more easily.

#SwoleLyfe the Buzzwole@Leftovers
Ability: Beast Boost
Adamant Nature
EVs: 204 HP/192 Atk/12Sp. D/100 Spe
-Substitute
-Focus Punch
-Leech Life
-Poison Jab
Buzzwole provides us with some bulky offense and a bit of utility to keep the team in it. I went with the SubPunch set for two reasons, 1- I'm a sucker for SubPunch sets and 2- it provides Buzzwole the benefit of some protection. Now that that's out of the way, Buzzwole hits like a truck. Substitute and Focus Punch are obviously the core moves of this set, allowing Buzzwole to get off a mighty Focus Punch from behind the safety of a cute little Poke Doll and deal tons of damage to whatever decides to face the 'Swole head on and help grab a KO and a Beast Boost. Leech Life is a nice secondary STAB option and gives Buzzwole a bit of recovery, allowing it to set up more Substitutes. Finally, Poison Jab is a nice coverage option for Fairy types that can hit decently hard, especially if it has a Beast Boost up.

Mufasa the Landorus-T@Rocky Helmet
Ability: Intimidate
Impish Nature
EVs: 252 HP/216 Def/24 Sp. D/16 Spe
-Stealth Rock
-Earthquake
-U-Turn
-Stone Edge
And, forming the second half of the team's defensive core, is Landorus-Therian. Defensive Landorus-T is a truly phenomenal Pokemon, and combines for a really solid defensive core with Tapu Fini, and Ground/Flying gives him two immunities. Landorus-T is the most common choice for a lead I got with as it is very good in a variety of sitautions. The set here is pretty straightforward. Stealth Rock is pretty much mandatory for any team in OU, and Landorus-T is a great setter of it. Earthquake gives Landorus-T a very powerful STAB attack that can combat Steel, Rock, and Fire types effectively. U-Turn is a great move for keeping momentum, and allows Landorus to form a nice VoltTurn core with Magnezone. Finally, Stone Edge adds some Rock type coverage that the team otherwise lacks, allowing Landorus to check the likes of Volcarona, and has amazing type coverage alongside Earthquake.

Jets the Latios@Life Orb
Ability: Levitate
Timid Nature
EVs: 252 Sp. A/4Sp. D/252 Spe
-Draco Meteor
-Psyshock
-Recover
-Hidden Power [Fire]
Last, but certainly not least, we have Latios. Latios is on the team for a couple of reasons. First, he rounds out the team's Fairy/Dragon/Steel core, giving the team a large variety of resistances. Secondly, Latios is pretty fast, and speed is something the team was lacking a bit. Thirdly, Latios hits like a truck from the Special side, and the team was lacking a general attacker. The set itself is pretty standard. Draco Meteor is a nice nuke that can take out a large variety of threats, and makes the team less susceptible to the likes of Garchomp or Salamence. Psyshock is a nice secondary STAB option that lets Latios hit opposing Special walls on their physically defensive side, and also provides great coverage against the likes of Buzzwole. Recover is nice to have to gain back some HP, and lets him live longer with the Life Orb. Finally, Hidden Power Fire rounds out the coverage, and lets Latios hit the likes of Tangrowth or Ferrothorn much harder.
In Closing:
Well, there's the team. Thanks for taking the time for reading through this RMT, and I appreciate any suggestions you have to make the team better. Mega Metagross is an absolute monster and Metagross himself has been one of my favourite designs for a while, so I'm glad I finally got around to building a team around him. The team works really well right now but I know it can always be improved upon. I appreciate any rates I might get. Thanks for reading!
