Lucario left 4th Gen as a huge late game threat. This generation is no exception! This team is built around a Swords Dance Lucario sweep. I chose Lucario because of his excellent typing, making it easy to set up for a sweep. Not only does he have a great attack stat, but he also looks amazing, and has priority to patch up the issue of his average speed stat. Despite all these great characteristics, Lucario is by now means perfect, so let's see his teammates that help him lead to success!
The Team
Lucario (M) @ Life Orb
Trait: Inner Focus
EVs: 4 HP / 252 Atk / 252 Spd
Adamant Nature (+Atk, -SAtk)
- Swords Dance
- Close Combat
- ExtremeSpeed
- Bullet Punch
The main sweeper of the team. I chose SD Lucario because of his ability to continue sweeping past Lati@s, Starmie, Landorus, and other threats that are KO'd by +2 ExtremeSpeed, but not +2 Vacuum Wave. Crunch was tested for a short while, but the ability to sweep past Terrakion and Gengar was too much to pass up. Jellicent does become more of a threat, now, but with Rotom-W being changed to a Trick Scarfer, the power will make up for not hitting Jellicent super effectively.
Heatran (M) @ Air Balloon
Trait: Flash Fire
EVs: 4 HP / 252 SAtk / 252 Spd
Timid Nature (+Spd, -Atk)
- Stealth Rock
- Flamethrower
- Earth Power
- Hidden Power [Ice]
Heatran is a great canidate for this team, not only because it complements Lucario with Flash Fire, but it is also an extra way to deal with Dual Dragon Teams, because with SR and the ability to check Dragonite, and most DD Mences, with HP Ice, as well as opposing Landorus. Not only does this help against Sun Teams, but I can also wall most common stall-breaker sets, like Sableye or Mew, meaning that I won't have to hope that I outspeed or KO with ExtremeSpeed. When rocks are up, this is a more reliable way to deal with Scizor.
Rotom-W @ Leftovers
Trait: Levitate
EVs: 4 HP / 252SAtk / 252Spd
Timid Nature (+Spe, -Atk)
- Volt Switch
- Hydro Pump
- Hidden Power [Grass]
- Pain Split
Rotom-W is a pretty solid addition offering Water Typing, which helps out with synergy offensively, and typing wise. HP Grass is a nice addition to counter Gastrodon, as only the Choice Specs varient carries HP Grass, itself. Pain Split helps weaken Blissey so they are forced to heal as I Volt-Switch, almost always guaranteeing Lucario free setup. I outspeed every varient of Gliscor that isn't a Jolly AcroBat, although HP Grass can break subs, so I'm not too worried. Rotom-W can also safely switch into Heatran if it is not the rare Sunny Day set. With Scizor and Landorus, I can form a Volt-Turn core, and Lucario can freely set up an SD late game, and do what it's been known to do.
Landorus (M) @ Choice Scarf
Trait: Sand Force
EVs: 252 Atk / 4 SAtk / 252 Spd
Naive Nature (+Spd, -SDef)
- Earthquake
- U-turn
- Stone Edge
- Hidden Power [Ice]
I have Landorus as my Scarfer because it can revenge kill Dragons, keep up momentum, and form as a parallel sweeper to Lucario, with HP Ice, who in return can OHKO Skarmory at +2 when SR are in play. It can also form as a Terrakion check, as it can never OHKO Landorus unless it's carrying Rock Gem, where Lucario or Scizor can BP. It is also capable of outspeeding Dragonite, Gyarados, Volcarona, and Mence at +1 and can swiftly KO with the appropriate move.
Jirachi @ Expert Belt
Trait: Serene Grace
EVs: 128 Atk / 148 SAtk / 232 Spd
Mild Nature (+SAtk, -Def)
- Psychic
- Hidden Power [Ice]
- Iron Head
- Thunderbolt
Jirachi is here to patch up a Tornadus weakness. I chose this strange Lure set over Latios because it can suprise most Gliscor with HP Ice, who might expect a SpD Jirachi that it can set up on. Iron Head is for Tyranitar and I can possibly flinch-hax Blissey to death, if I have to. Thunderbolt provides a pseudo BoltBeam Combo. It also helps with Skarmory, who Jirachi cannot usually touch. With the speed EVs, I reach 294 Speed, which is enough to outspeed base 80's, which means I can flinch Dragonite if my Rocks are spun away, and KO with HP Ice. Psychic hits Tentacruel hard, who can otherwise Spin Rocks away, but I don't think it's anywhere near an OHKO.
Scizor (M) @ Choice Band
Trait: Technician
EVs: 152 HP / 252 Atk / 104 Spd
Adamant Nature (+Atk, -SAtk)
- U-turn
- Bullet Punch
- Pursuit
- Superpower
Last, but certainly not least, we have Scizor. Scizor is great because it traps Gengar and Lati@s, who can potentially stop Lucario's sweep. This guy is also a great check to Reuniclus, who the rest of the team is threatened by. Scizor also helps with Terrakion, who is one of OU's most threatening sweepers. I run enough speed to outspeed Purely SpD Heatran. Scizor can also outspeed most Jellicent, and U-Turn to Rotom-W in case they try to burn it. BP is nice because it greatly threatens most offensive teams, and can help Lucario weaken down an opposing Scarfed Landorus, who can live +2 ExtremeSpeed.
