A nitpick here, but Scizor should use an Adamant nature and 248 HP/252 Atk/8 Spe to make the most out of its power and defensive capabilities. Technician is also the preferred ability to boost Bullet Punch's power.
Latios currently is walled by Heatran. Hard. Surf is its best bet for dealing with it; you may have to give up Psyshock or Recover for it. You might as well go with a 252/252 EV spread because I don't really see what purpose your current spread serves.
Other than that, your team looks fine, apart from the fact that half your team is vulnerable to Dark Pokemon like Tyranitar. I'll let someone else figure out what else to add.
