[Tabuu]

I hope you realize that the following happens for Lucario:
If it runs Crunch: It just needs Pokemon such as Terrakion, Gengar, Scarf Tyranitar, Landorus-T and Gliscor out of the way.
If it has Ice Punch: Pokemon such as Jellicent and Reuniclus need to go.
If it has Bullet Punch pokemon such as Slowbro Jellicent and Gliscor need to be eliminated first.
After these requirements are fulfilled, along with the assist of LO, SD and SR, nothing can stop a Lucario sweep.
