It definitely lacks the strength of a +2 Lucario. But thanks to Agility, with the help of Hazards (usually SR and a layer is optimal), Lucario at +2 Spe, can really abuse his coverage with Close Combat, Crunch, and Ice Punch. Even without an SD, with Max investments, LO, and an Adamant Nature, Lucario can KO so many threats. Of course Lucario still has its evident flaws mainly Bronzong,Skarmory, Slowbro, Hippowdon, Jellicent, and Techniloom but it really fits in well with this meta.
...And that's all I have to say haha.
Thanks for considering it :D
