THE LEAD
aerodactyl @ focus sash
Nature: jolly
EV: 4 HP / 252 Atk / 252 Spe
-stealth rock
-taunt
-earthquake
-rock slide
i went through a decent amount of leads before finally deciding on aerodactyl. basically i want to ensure that i get rocks out and decided that aerodactyl has the speed to do it and focus sash pretty much guarantees that this gets done. he also has the option to taunt to prevent others setting up rocks. he is definitely a suicide lead and i don't really expect him to survive to long after setting up rocks. the other main lead i considered was azelf along with metagross (figured that was just too much steel).
THE BAIT/BACKUP SWEEPER
Scizor @ Choice Band
Nature: adamant
Ability: technician
EV: 248 HP/ 252 Atk / 8 Spe
-U-turn
-Bullet Punch
-Superpower
-Pursuit
Scizor would probably be played immediately after the lead assuming he's not switching into certain death. his main purpose on the team is to ensure that lucario's foes are taken care of before he is sent out. once someone new switched in u-turn out and let someone else do the dirty work. he would also serve as a decent backup sweeper to clean up whatever the rest of my team couldn't. also makes a great revenge killer bullet punch.
THE STAR
Lucario @ life orb
Nature: jolly
Ability: inner focus
EV: 252 Atk / 4 Def / 252 Spe
-swords dance
-Close Combat
-ExtremeSpeed
-crunch
The whole team built around this guy. he's got a pretty straightforward swords dance move set and support from magnazone to pull it off. close combat for its raw power, extremespeed for revenge kills, and crunch to take care of everything else. i went back and forth a little on having an adamant or jolly nature but in the end decided i'd rather ensure that i can outspeed other pokemon such as impish gliscor or jolly gyarados. life orb as the held item for that little extra oomph.
BODYGUARD #1
salamance @ life orb
nature: rash
EV: 16 Atk / 240 SpA / 252 Spe
-draco meteor
-brick break.
-flamethrower
-roost
Here to make sure lucario is able to get his job done and take out his main offenses. one of two options to be u-turned in by scizor. i went with the mixmence set particularly for draco meteor which can easily take out many of lucario's counters. brick break is there to break screens and prevent stalls. flamethrower to take out steel and roost to ensure that he will last a while.
BODYGUARD #2
Starmie @ expert belt
Nature: timid
Ability: natural cure
EV: 4 hp / 252 SpA / 252 Spe
-surf
-ice beam
-thunderbolt
-grass knot
the second option for scizor to u-turn is starmie. he has great type coverage. originally went with choice scarf on him but decided i wanted the better type coverage and didn't want to be bound to one move. surf is his main offensive move since it has STAB. everything else can be used when it has type effectiveness. Timid is the obvious choice for nature with the choice scarf giving it that much more speed.
THE SUPPORT
Magnezone @ light clay
Nature: relaxed
EV: 252 HP / 96 Def / 162 SpD
-reflect
-light screen
-thunderbolt
-explosion
went through a couple of screeners but ended up with magnezone mainly because of a gyarados weakness that my team had. he takes care of that with thunderbolt for an offensive move. otherwise his main purpose is to set up screens and explode giving lucario time to set up a few swords dances. the EV's given to him are to ensure that he doesn't get OHKO by a Timid Heatran's Fire Blast or Timid Gengar's Focus Blast. Along with that they also prevent being 2HKOed by an Adamant Jirachi's Fire Punch and will never be OHKOed by a standard Bronzong's Earthquake
