Please tell me which move I should pick for Latios' second move slot, either Psyshock, thich deteriorates Venasaur-Mega, HP Fighting, which takes care of Bisharp and Tyranitar, or HP Fire, which destroys Ferrothorn. Please notice that my Excadrill is scarfed and has the ability Sand Force. Tell me if I should use Sand Force or Mold Breaker on my Excadrill. If you see some flaws, please tell me how to correct them. Anything is appreciated. Thank you.
