Introduction

This team started with the idea of using Defiant Thundurus since Bisharp is much more difficult to use Thundy is the next best thing to punish defogs.


Landorous was then added for the SR support Thundy needed and because its explosion hits super hard and can break any defoggers who choose to stay in on Thundy.



Keldeo was then added since its a strong wallbreaker with a great speed tier who draws in all the defoggers that Thundy enjoys abusing: The Latis, Fini and Mantine all find Keldeo to be an easy switch-in.




I wanted a revenge killer who could beat up Ferrothorn and I hadn't used scarf Pheromosa at all yet in the metagame.





I need an answer to powerful special ice type moves and Tapu Lele so I added AV Magearna who's slow volt turns were definitely appreciated.






Tapu Lele offered a way to deal with Scizor and psychic terrain helped Pheromosa but honestly this was a bad pick with the way the team was set up






I'll start with the simple one despite being more obvious and less powerful the speed Azelf provides allows me to more easily set up rocks and guarantee their set up vs. stall which is crucial to the matchup. At the same time I got rid of Magearna who didn't fit on the HO vision that I was building now for Scarfchomp which freed Pheromosa to move to a Quiver Dance set.






I wasn't happy about being forced to run Tapu Lele for Phero support since it provided relatively little to the team. So I had to get rid of Phero and Lele at once and decided to grab Tapu Koko and Mega Meta. Metagross provided a check to powerful psychic type moves and Tapu Koko to speed creep greninja and because Koko really appreciates Thundy luring in and KOing its checks like Defensive Lando.






It wasn't worth running Keldeo when Ash-Ninja provides a nice offensive pivoting core with Koko while also performing Keldeo's role of drawing in Fini but without having to deal with Mega-Gross being able to check and KO you thanks to Ash-Ninja's speed tier.
Apologies about that taking so long so lets get to the team!
Azelf @ Focus Sash
Ability: Levitate
EVs: 4 HP / 252 Atk / 252 Spe | Jolly Nature
Stealth Rock | Explosion | Skill Swap | Taunt
Azelf is a covenant with the Pokegods, the deal is that if you use Azelf you use a slot solely to guarantee that you get SR up while your opponent does not. There is not much to say about this set since its pretty well known. One of my favorite parts of Azelf is that it draws in Scarf Lando thinking they can U-Turn while I taunt then KO me with priority to stop me form setting rocks, but I just set up SR everytime even if they set their own and knowing whether I'm facing Scarf Lando allows me to protect Tapu Koko way easier.
Thundurus @ Flyinium Z
Ability: Defiant
EVs: 208 Atk / 48 SpD / 252 Spe | Jolly Nature
Knock Off | Fly | Wild Charge | Superpower
Onto the MVP of this team Defiant Physical Thundurus, Thundurus is an amazing balance and stallbreaker with this moveset. Since this set is very rare and it has incredible coverage most teams don't have a good switch-in to Thundurus. Thundurus alongside hazard support from Azelf bends stall backwards and on top of that cannot be trapped by Dugtrio. Since, Quagsire is rarely seen on stall these days it just goes to town on these teams and opens the way for Tapu Koko and Greninja to clean up. Thundurus has a 50/50 to OHKO Defensive Lando (since it gets plus 1 on switch in thanks to defiant) and only really has trouble with Rotom Wash on Balance who is much rarer these days. Thundy does get revenge killed fairly easily by the omnipresent Greninja and Tapu Koko but by then its already done its job and opened up a hole for Tapu Koko to pressure the opposing team. Thundurus's Z-Fly also chunks Scolipede for half its HP even on a protect which allows me to break Scolipass with ease.
Hey Whats with this weird Sp. Def Investment?
This investment allows Thundy to survive a LO Pheromosa Ice Beam or a Specs Greninja Dark Pulse + SR and a have fairly high chance to survive a Specs Hydro Pump from full which allows me to lure these threats and KO them when they attempt to revenge kill thundurus.
Ash Greninja @ Choice Specs
Ability: Battle Bond
EVs: 252 SpA / 4 SpD / 252 Spe | Timid Nature
U-turn | Hydro Pump | Dark Pulse | Water Shuriken
I've already talked a bit about the dual purpose of Specs Greninja on this team. Specs Greninja both draws in Tapu Fini and other water types who Thundurus abuses but also revenge kills weakened threats and forces switchs which allows me to U-turn to gain momentum. Tapu Koko + Greninja is a fairly common offensive core since they are able to continually force switches through U-Turn and rack up SR damage.
Tapu Koko @ Life Orb
Ability: Electric Surge
EVs: 252 SpA / 4 SpD / 252 Spe | Timid Nature
U-turn | Volt Switch | Thunderbolt | Hidden Power Ice
Tapu Koko is the second part of my Volt Turn Core with Greninja. I chose life orb since it allows me to KO more easily despite the damage to myself on U-Turn. I chose not to include Brave Bird since Thundurus does a pretty good job of luring in and KOing its main target: Tangrowth. Instead Volt Switch allows me to obtain more powerful momentum once the opposing teams ground types are KOed which again Thundurus assists with. Tapu Koko makes a very nice cleaner against more offensive teams and only has to worry about Pheromosa.
Mega Metagross @ Metagrossite
Ability: Tough Claws
EVs: 252 Atk / 4 SpD / 252 Spe | Jolly Nature
Meteor Mash | Bullet Punch | Ice Punch |Earthquake Hammer Arm
Oh hey look its Mr. OU himself Mega Metagross. Metagross is just a generally fantastic pokemon who assists with dealing with Tapu Lele + Pheromosa offense teams.Agility is a really underrated move and despite giving up some coverage to use it allows Metagross to be a stop to offensive teams and volt turn shenanigans. The Team Archetypes such as Tapu Lele + Phero or Mega Zam offensive teams have not been as prominent on ladder as before and as I result I felt comfortable swapping out Agility for Bullet Punch since setting up an agility is difficult and Bullet Punch assists in dealing with Pheromosa who has been much more popular. Since I'm not planning to use Agility all the time I decided to keep with Jolly since one of mega metagross's main selling points is its nice speed tier. Ice Punch breaks Landorous and Earthquake kills Heatran and other Metagross. Hammer Arm is better at pressuring Ferrothorn who is a nessecary pokemon to wittle down and other Metagross aren't that dangerous given that I run multiple mons that outspeed them. I don't feel the need for zen headbutt since its primary target: Keldeo isn't a threat to the rest of the team.
Garchomp @ Choice Scarf
Ability: Rough Skin
EVs: 252 Atk / 4 SpD / 252 Spe |Naive Jolly Nature
Earthquake | Outrage | Rock Slide | Fire Blast
Scarf Garchomp is a my required revenge killer and deals with DD-Zard, Mence and Mega Pinsir who otherwise can stop the rest of the team without a fight. Garchomp also cleans pretty well and can use Rough Skin to break sashes if I'm desperately needing a revenge kill. Fire Blast is there for if I really need a Ferrothorn dead. Garchomps typing and bulk allow him to deal with a lot of priority that would otherwise stop him from revenge killing.
Conclusion + Threatlist + Importable
This is by far my favorite team I've built currently and I feel that Defiant Thundurus is massively underrated and can provide a unique team support unlike any other pokemon in the tier. This team turned out pretty well I haven't gotten a chance to really ladder hard with it and probably won't for a while due to how busy I'm going to be getting. Thanks for reading and feel free to use this team if you want, let me know how it goes!
I don't like Spikes and I don't have an easy way of KOing Ferrothorn Thundurus can chunk it with Superpower but it is probably the biggest wall in the way of this team that you can see at preview.
Ash Greninja is a large threat due to its speed tier and the fact that this team doesn't carry any water resists. Due to this fact Greninja users are oftentimes overeager to get Greninja's form changed so they attempt to revenge thundurus which gets them KOed in return due to sp. def investment. Otherwise its just a matter pressuring Greninja out multiple times during a match.
Like with Greninja, Scarf Gengar is able to outspeed and pressure my team especially with Shadow Ball who only Greninja resists (and greninja isn't exactly bulky)
Trick Room
This is a HO team which means that it Auto Loses to Trick Room its just part of the territory.
This is it off the top of my head but I'm sure there are others
