Lucario is one of my favorite mons, and for the past few days I have been thinking really hard about how best to use him in OU. I know currently he's UU but he still has some key advantages that make me want to use him. The set I settled on was the SD set. Contained within is my teambuilding process, and unfortunately, the wall I've hit. I lose about as many games as I win with this team, I think some of it might be down to my own misplays but I think there also might be some flaws in my thought process. So please, rate the team.

I began with lucario, I settled on the SD set since it has immense offensive presence and puts pressure on my opponent's team.
From here, I decided on the moves, Extreemespeed, Ice Punch, Close Combat. I felt like Extreemespeed would be needed since Lucario is not the fastest pokemon (he's fast, but not that fast). The priority came in handy so many times. The Close Combat is the reason that this set was even considered. Granted anyone who has CC is powerful, but Lucario has some advantages in his resists and the moves he is immune to. Most importantly, he is immune to poison, so he can take advantage of a fairy type team mate. While he's also immune to toxic, which many defensive walls run. Lucario has the power after a SD to obliterate many defensive walls in the metagame. Ice Punch I felt would be needed for the omnipresent genie and for Latias.


It became very clear, that Gengar would be a huge pain for this set to get past, especially since Steel lost it's ghost type resist. E-speed means also that Lucario has no way of hitting Gengar before it makes it's attack, so I chose a special defensive Tyranitar (with an assault vest) as a team-mate to check Gengar. This Tyranitar set has proven particularly effective in testing.



I already mentioned having a fairy type team-mate was important for this set, so I decided to use Sylveon, though at first, I was unsure what set to use on it. I settled on the specs set after a while, but originally, I was unsure about this spot, I tested a lot of things (including Dusknoir, of all pokemon) Sylveon is proving his worth, but the Specs set requires a lot of prediction.




With Tyranitar invested in special bulk, and Sylveon having the DEF stat of a paper bag, I needed a physically defensive Rotom-W to act as a pivot, and to help check Lando.





This slot was one I struggled with a lot. Lucario's chosen moves (and notable lack of steal-type attack) made my team Clefable weak, while I also needed a pokemon to setup rocks. I felt like Ferrothorn would be the best bet, and I tried to work out what kind of attack he would need in order to do enough damage to fairy types with his Gyro Ball. I also realized that Slowbro was a big problem for the team so he carries dual stab and SR.






Lastly, I needed a mega, and I felt like I needed a Ghost Type. I also wanted something that was more of a tank on the physical side. At first I felt like Sableye was a natural choice, but I did doubt myself a lot on what moves he should run. Currently, I want him to be something he's not I think, a stallbreaker set.
And then I decided to nickname everyone after an Element.
Posting this thread gave me a lot of help, and the team improved though my battling style was a little bit off for it for a while.






After a bunch of testing, I switched Ferrothorn out for Ballontran at the suggestion of D-Raven and I messed around with the Sableye set.






With Sparkl3y's suggested Sableye set the pokemon was putting in work. I realized the team was now more about Sableye and less about Lucario. I also realized that heatran wasn't quite giving my team what it needed, I decided to test out gliscor and it's working out rather well. Currently its a weird baton pass set, which seems to be working out alright. This 'forced' me to remove BP from Sylveon, so I tacked on HP fire to destroy steel types.

Iron (Lucario) @ Life Orb
Ability: Inner Focus
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Close Combat
-
- Extreme Speed
- Swords Dance
The man, the legend, Lucario. Lucario serves as my offensive powerhouse. He exists to break holes in my opponents defensive cores and smash heads open with Close Combat. The primary reason I felt like this could work is people are still using Chancey and Ferrothorn. Lucario loves these slow defensive pokemon as they lack the hitting power to truly take him out before he destroys them. Kibblekat told me to swap to an Adamant nature as you nab key KOs that you miss with Jolly (and there isn't really anything I outspeed anyways other than Altaria, and maybe Jolly Bisharp but who uses that??). Close Combat is the point of the set, Extreme speed gives me some priority meaning that he can knock out a weakened opponent before it can revenge him. Ice Punch was chosen to fully obliterate dragons, and to give me something to hit Lando with. It can also nail Gliscors who lack EQ (I've seen it, alternatively it can nail them on the switch if they are trying to predict a close-combat). It also deals significant damage to Venusaur-Mega. At first I swapped over to Iron Tail on a whim, to test it out, I found that it did pretty much whatever Ice Punch did but it Made him a much bigger threat to Sylveon and Clefable. This is important because those two pokemon can setup for free on Mega Sableye. With this set, Lucario is kinda serving to help open the door for M-Sableye to start setting up. Iron Tail also 1shots Diancie.

Silicon (Tyranitar) @ Assault Vest
Ability: Sand Stream
EVs: 232 HP / 24 Atk / 252 SpD
Adamant Nature
- Stone Edge
- Earthquake
- Crunch
- Dragon Tail
This set began as a silly idea while I was playing XY. "Hey, if I put AV on Tyranitar he basicaly gets double Spdef because of sand!" Thus, AV Tyranitar was born. AV does mean that he can't really do much support for the team, but he still hits really hard. Stone Edge is his primary STAB move that I find myself going to a lot (and I kick myself every time it misses). Crunch is a reliable way to remove a Latios from the game. With this much special defense, even a Draco Meteor will harmlessly bounce off of Tyranitar. Earthquake gives additional coverage for things like Heatran which would wall this set otherwise. Dragon Tail is kinda the odd move out. It does work with AV, and it helps me counter setup pokemon who want to come in and gather up calm minds ('cept clefable, who happens to be immune to dragon :/ ) I have noticed that when I use this set, as soon as Dragon Tail is revealed, people start switching fairies into him on the predicted dragon type move, but the first time they see it it usually catches people off guard. Tyranitar has this way of forcing people to switch out, and Dragon Tail can take advantage of that. Changed Dragon Tail over to Pursuit, at the suggestion of DarkNostalgia and others. Pursuit does the same thing that Dragon Tail did only it actually kills Gengar, rather than bopping what they sent in. However the strangest thing about this set, is I added it to counter Gengar, who typically carry focus blast. A bit concerned, I ran a calculation.
252 SpA Gengar Focus Blast vs. 232 HP / 252 SpD Assault Vest Tyranitar in Sand: 184-220 (46.1 - 55.1%) -- 62.5% chance to 2HKO
(184, 188, 188, 192, 192, 196, 200, 200, 204, 204, 208, 208, 212, 212, 216, 220)
(184, 188, 188, 192, 192, 196, 200, 200, 204, 204, 208, 208, 212, 212, 216, 220)

Hydrogen (Rotom-Wash) @ Leftovers
Ability: Levitate
EVs: 216 HP / 252 Def / 40 Spe
Bold Nature
- Volt Switch
- Will-O-Wisp
- Hydro Pump
-
Rotom-W is my main defensive wall and serves as a check to Lando-T. Volt-Switch helps me build momentum and allows a safer switch for some of my more frail team-mates. Will-o-Wisp racks up passive damage and is a big threat for people switching around, especially if they want to switch in a dragon dance sweeper like Dragonite or Altaria. Hydro Pump is required for Rotom-Wash but it also is a big threat to Lando-T, and usually forces it to U-Turn or get obliterated (unless I miss). Hydro Pump can also deal heavy damage to pokemon that don't resist water. I went with Thunderbolt as a more spamable stab attack and as a way to deal more damage to bulky water type pokemon who resist Hydro Pump and can take a volt-switch with ease (such as Slowbro) Pain split was chosen as a method of recovery but it also allows this pokemon to deal damage to Chancey, which otherwise it can't do anything against. Pain Split allows it to exploit special walls and get all it's health back.

Silver (Ferrothorn) @ Rocky Helmet
Ability: Iron Barbs
EVs: 68 HP / 188 Atk / 252 SpD
Sassy Nature
IVs: 0 Spe
- Power Whip
- Gyro Ball
- Stealth Rock
- Leech Seed
I struggled a lot with these next two pokemon, and I have finally got a set here that I at least feel can do the job I asked it to do. I wanted a way to check Clefable. The given EVs allow me to 2HKO defensive Clefables after SR and Leftovers. Everything else went into bulk. Power Whip I felt was needed for Mega-Slowbro who could setup on this pokemon otherwise. Leech Seed is my only method of recovery. I stuck the helmet on there to punish the U-Turn spam you tend to see these days. Stealth Rocks are very important for my team, and Ferrothorn has plenty of chance to set them up due to his seeming invincibility.

Platinum (Gliscor) @ Toxic Orb
Ability: Poison Heal
EVs: 184 HP / 252 Atk / 72 Spe
Adamant Nature
- Swords Dance/Taunt
- Baton Pass/Knock Off/U-Turn
- Stealth Rock
- Earthquake
Where to begin with this set. At first it might look strange, but it's your standard SR Gliscor at least in terms of HP and Speed, however, I wanted to use a variant with Baton Pass. Originally there was a heatran in this slot, but I found myself heavily invested in special attackers doing that, and I thus lost to teams with a strong special wall if Lucario got taken out early. This set also serves as a tank for hits that might go into Lucario and Tyranitar, he covers the team really well. Currently I am using SD Baton Pass because I love the idea that he can start the setup, and then when the opponent switches in what they think is a counter I can BP to either Lucario or Tyranitar, both of whom greatly appreciate a swords-dance. (Alternatively I could play a bit more "standard" and run Knock Off and Taunt, Knock off gives me something to hit floating opponents with as currently this set can't do anything about a balloon.) As always, this is the space on my team devoted to rocks, and this guy has proven a little better at it than balloon-tran. EQ is chosen as the primary attack as it is his most powerful move. Max attack was invested so that I can 2HKO common walls after 1 Swords Dance, and even without the boost, noone expects Adamant, the extra damage comes in handy for the rest of the team. Also somewhat considering Rock Polish over SD to help out against HO teams.

Carbon (Sableye) @ Sablenite
EVs: 252 HP / 192 Atk / 64 Def
Impish Nature
- Will-O-Wisp
- Recover
- Knock Off
- Taunt
Ability: Prankster
EVs: 252 HP / 252 Def / 4 SpA
Bold Nature
IVs: 0 Atk
- Calm Mind
- Recover
- Will-O-Wisp
- Shadow Ball
TYVM for this set Sparkl3y! I donno what I would have done without it. First of all, CM Sableye is a natural pair with SD Lucario, and for reasons Kibblekat suggested I have decided to go with Shadow Ball (it also hits Gardevoir harder than dark pulse, and this team is kinda weak to Gardevoir.) Shadow Ball and Dark pulse have nearly identical super effective coverage but the big advantage to Shadow Ball is the Spdef drop chance, giving me a chance to win CM wars (and I have fought so many CM wars with this set and things like Cresselia/Slowbro). Recover means that he stays healthy and it can also be used if he hasn't mega evolved to heal off some prior damage. WoW is actually essential for winning CM wars as well, as the passive damage can really rack up and you only have so many recovers. Calm mind gives you that bost and after a few calm minds there are very few things that can take a Sableye out of the game, but this set has to Mega Evolve safely. Sometimes I lead with it but it's very risky as many times I need it as my win condition.

Argon (Sylveon) @ Choice Specs
Ability: Pixilate
EVs: 248 HP / 252 SpA / 8 SpD
Modest Nature
- Hyper Voice
- Shadow Ball
- Psyshock
-
This set, is quite strange, I won't lie I have had more doubts about this set than any other on the team. However, even with my doubts, it does put in work. Before I started using it I wasn't convinced, but after seeing Argon obliterate pokemon in 1 hit from a neutral Hyper Voice, I was sold. Hypervoice is a very strong attack, and being a sound move, it goes around subs! This fact alone makes this pokemon wonderful against sweepers who rely on hiding behind a sub, thinking they can tank hits with it. Shadow Ball hammers Skarmory and other physically defensive steels really hard, it also hammers Metagross. Psyshock is there to deal with opposing Sylveon, and most of the things that would do super-effective damage to Sylveon, its also handy for Venusaur. Baton Pass is there so it can build momentum or if I think my opponent is about to make a switch. It also forms a janky pass-turn core with Rotom. I switched over to HP Fire since due to the Gliscor set I was forced to because of BP clause. I didn't really miss it as I appreciate the power to 1shot ferrothorn over the janky prediction nature of BP on this set.
And there we go, that's the team. This is my first RMT on the form and I'm making it because I need help. I wanted to try using Lucario on the ladder but my team still has glaring weaknesses I didn't think about. Despite the amount of time I spent trying to counter every threat there are still threats out there that annihilate my team.
Threatlist!
Talonflame is a somewhat large issue, but only if Rotom and Tyranitar are taken out. Keeping rocks up are important against Smogonbird as always. Lando, captain of the millenium falcon is also a big problem. I'm speaking of incarnate form specifically as HIS focus blast CAN 2OHKO Tyranitar reliably even through the sandstorm, and he deals way too much damage to Sableye with his earth power for that to be a good counter. The T form is somewhat of an issue if Rotom is gone, but it depends on what set it is. A scarf set can't hurt Gliscor, but a fully defensive set means that I'm relying on predicting it with a Hydro-Pump or stone-edge in order to take it out. As mentioned Clefable is also a massive problem, though in this regard I'm particularly afraid of the unaware variants. Magic Guard is irritating, but assuming I can get my Swords Dance off Espeed should still 2HKO. (Iron Tail is an option I keep turning over though since it does OHKO after a swords dance, Unaware is an issue but Irontail still 2HKOs it, and if they have no Calm Minds they can't do enough damage to Lucario before it destroys them.) Another big problem is Sylveon since Hyper Voice is strong and threatens so much of my team, that it's often left to do as it pleases weather its wish-protect or Calm-Mind. On that note Mega-Gardevoir can also be a big issue since I have no real counter to it and to beat it Tyranitar will have to be full health. Also Sableye and Gengar are still massive problems to the team as Lucario cannot eat a shadow-ball and Sableye typically carries Will-o-Wisp (which has priority under prankster) If Tyranitar is gone and Sylveon weak then either of them can destroy my whole team. Another big problem is Excadrill since he's faster than Lucario anyways and Mold Breaker variants are quite dangerous. As expected M-Lopunny is the perfect counter to M-Sableye, but all hope is not lost, Sylveon just needs to be at full HP to avoid getting knocked out by a Return. A SD e-speed is enough to knock it out, but otherwise it is very dangerous to the team, Rotom gets 2HKO'd by return and it has an annoying habit of dodging my Hydropump.
