Nothing crazy but simple and effective : MiloGonLuc Spikes. I built a prototype like 3 months ago but I decided 10 days ago to finish it and optimize it for a tournament game. This is the definitive version for now.
First, Scarf Tar lead to get SR asap and trap Rotom / Gengar / Starmie. EQ to help against CM Jirachi. Sand Turn 1.
Skarm : some Speed EVs ( outspeeds 192 ) and Taunt to prevent others Skarm to stack hazards and annoy Milo / Luc. Outspeed some MixTars too so you can PP Stall Fire Blast PPs. And ofc SPIKES.
Gengar with some bulk and WoW + Taunt. Anti-Spin, helps a lot against Breloom ( Spore kek ), WoW coupled to spikes and Sandstorm is deadly. Taunt can help Lucario to setup on smthing and can also Stallbreak. More speedcontrol is also nice when your Scarfer is Tar. ( Stole the spread from a teamdump from Johnnyg2 iirc )
Milo A.B.O. ( Anti Bulky Offense ) : good answer to waters like Swampert / Kingdra Rain Dance / Gyara, Heatran etc. With SpA invests, a Modest nature and spikes, Hydro Pump become a dangerous move which is hard to switch into for a lot Bulky Offenses. A lot of speed for Breloom ( Hydro Pump + Ice beam or smtimes just Ice Beam = Breloom dead ), Zapdos etc. Some bulk to help against waters. ( Stole the spread from a team made by Emeral ). In short : walls everything and destroys everything with Hydro Pump and coverage.
Flygon : lures every answer to Lucario ( besides RKillers ) like Gliscor, Zapdos, Gyarados, Rotom etc etc etc. Very effective coupled to spikes. Outspeeds 317 and 318.
Last mon, Lucario. Stack spikes, trap the Ghost type, lure Gliscor etc with Flygon, find the opportunity for SD ( like a -2 Dragon ) and Luc will do everything else. Ice punch helps against ( if you didn't get rid of with Flygon ) Zapdos / Gliscor / Nidoqueen. Maybe you can go for Crunch > Ice punch, it helps a lot against Bold Rotom.
