Typed up a long response, but the site decided it would be cute to log me out rigt as I post it. >.>
Anyway, I haven't gotten to play for a couple weeks either, so I can't really speak for Lati@s. However, I think it would be best if Nite just ignores Terrakion. Scarf was Terrakion's least common set from my experience, and Terrakion itself isn't as common as Garchomp was. Furthermore, lulzer showed that you can't OHKO Terrakion with a +2 DClaw, which means he can beat you anyway. Also, there will always be something to outspeed. Why not beat Scarf Latia@s, or Scarf Thundurus, or Scarf Starmie... Using Jolly to "beat" Terrakion is just not worth the loss in power.
