The IVs are alright, though it wouldn't take too much longer to do better. I'd not use that one mainly because of the nature to be honest.
Take that axew, give it the power anklet to hold and breed it with a jolly ditto, having the ditto hold an everstone (or anything else in its egg group that's jolly). Every axew you get will be 50% jolly and 100% keep that nice IV in speed. All that you got to do then is wait for a 31 in attack and you're set. Shouldn't take too long
Not to mention you'll outspeed all those Hydreigon who decide to invest in a modest or adamant nature (as many do) for an easy KO
Although there's far too much to say about each of those in turn, I will say this: as a general rule, do NOT use a -speed nature on a pokemon unless its speed is so horrible that it can benefit from it (users of gyro ball are generally the only exception). In a game where most offensive pokemon go down in 2-3 decent hits, whoever gets that first hit in will most likely win. The four "main" sweeper natures are adamant, jolly, modest and timid and if you're not using one of those natures, you should have a good reason for it.
Also, just like to say that that riolu (lucario) won't be able to do anything to gliscor even if its life depended on it and gliscor is a very popular pokemon. you might want to rethink that set.
