Ohhh, run like Superpower > Fire Punch on Tar.
You already OHKO Scizor with Stone Edge, Superpower hits Ferrothorn and most things Fire Punch hits hard enough, BUT you get to hit other Tyranitar! :D
Also, you need Pursuit. Run it over Earthquake. Pursuiting Latios, or Latias is a game defining play. I don't see why you aren't running it.
