Great team. When all priority is removed and Empoleon sets up Agility it's GG. Jimbon has done a great job improving the minor "faults" in this team, but I'd like to make one more suggestion: Try Substitute over Fire Blast on Volcarona. If you do this, you have an insurance you won't be revenge killed straight away by Tornadus-T and after a Quiver Dance, Hurricane will hit him very hard.
Hope I helped and Good Luck!
