Looking at this I have a few comments:
@ Swords Dance set,
You mention a that Dragon and Grass resist fighting. This is an inaccurate statement. I would put common in front of that, which implies that you are specifically talking about Salamence, Dragonite, Celebi, and Shaymin-S.
@ Agility Mix set,
I don't like the EVs for this at all. Why is there such a small physical attack investment? I know only 80 are needed to beat Blissey, but Blissey isn't the reason that Close Combat is on the set. Close Combat is Lucario's most powerful move and should be use to sweep should you come accross a weakened team. For starters, since the special moves are specifically used to clear away specific walls, I would start with that. You need 298 Special Attack to have greater than a 50% chance to 2HKO on Hippowdon with Stealth Rock, taking Leftovers into account, so I would set my special attack there. Then, you don't need quite so much speed. 265 Speed (196 EVs) is enough to outrun Scarf Shaymin-S after an agility, and isn't losing out on anything before an agility, so I would drop a few Speed EVs. Then to take advantage of Close Combat as your main attack, dump the remaining EVs into attack. It should look like this:
188 Atk / 128 SpA / 196 Spe, Naughty
Yields:
332 Atk / 298 Spe / 265 Spe
With a Rash nature and only 80 Atk EVs, your Close Combat is doing approximately 16.5% less than mine. Furthermore, I'm keeping the same 2HKO on Celebi with Dark Pulse / Shadow Ball, and a good chance at a 2HKO on Hippowdon as well. I don't know what else all that Special Attack is needed for when your using unSTABed moves. Cresselia isn't 2HKOed by either spread so I don't know why you need so much Special Attack.
@ Counters section:
Gliscor is the #1 counter, as it outspeeds Lucario and OHKOs with Earthquake. But it can't switch into Hidden Power Ice or Ice Punch. But then again, nothing that is a "counter" to Lucario can really switch into any set overzealously. I would drop the mention of Ice Punch Lucario beating Gliscor, because again, it won't unless it predicts the switch in. Gyarados loses to Stone Edge / Thunderpunch, Zapdos loses to Stone Edge / HP Rock / HP Ice / Ice Punch, as does Salamence. Blissey loses to Close Combat (why is this even mentioned? SpecsLuke has an 85% chance to 2HKO with Stealth Rock!). Spritomb hates Choice Specs Flash Cannon, but more importantly, hates the Swords Dancer, as a +2 Stone Edge OHKOs many versions of Tomb. Heracross may not care about fighting attacks, but the Swords Dancer destroys him too. Rotom appliances fear more than just crunch.... Shadow Ball and Dark Pulse destroy them too and I rarely see them being used Special Defensively. The intro to this is good about you have to know the set, but some of the proposed counters aren't too great. Oh yeah, no mention of Sub Calm Mind Jirachi always beating SD Luke? ALWAYS!! (Subs twice, than Psychic OHKOs after 2 Defense Drops).
