You could do better.
Given that the Lucario's holding a Salac Berry, you're trading off on the Lucarionite, which I don't find is lucrative, in light of the fact that 1. Lucario is swift as is 2. The Mega Evolution stone has a profoundly positive effect on it. Therefore, personally, if you're not going to give it the stone for whatever reason, such as you're using your Mega Stone spot for another Pokemon, of which is good rationale, opt for a berry/item that can be utilised better than your contemporary one.
Let's move onto your moveset, which isn't all that great either. Although ExtremeSpeed is not too bad an option, admittedly. It appears your moveset is tailored to defense - you've gone a bit overboard with that, which means you're not utilising its high offensive stats (vanilla or mega evolution) properly.
The offensive types are around the same, so you have some real scope here, given you have Attack and Special Attack at your grasp. USE IT. A moveset more effective from the top of my head would be:
- Aura Sphere; IMO, it's an absolute must.
- Shadow Claw; makes for some decent type coverage.
- Earthquake/Close Combat; if Electric types aren't a pain in the neck, opt for the latter.
- Swords Dance; a solid way of getting that attack up.
Personally, I feel it needs work - the moveset in specifics I've provided myself could too be better; but it's an overview of what you should be looking at. I imagine you won't get anywhere with your contemporary strategy - but in any case, I bid you good fortune. I'll also add that all this is on the basis of it being on X/Y; if it's on another game, I'll respond with a comment tailored to that generation.
