You have a Typhlosion but you're not running Eruption?
I know Typhlosion learns Eruption naturally, but if you use a heart Scale, you can get it anytime.
Since Typhlosion's natural coverage is terrible, i'd suggest >> "Sunny Day, Eruption, Flamethrower, Extrasensory" for now.
Eruption destroys lives, Flamethrower for when Nova's health gets down, Extrasensory coverage and Sunny Day for that added power.
This might the best you can get right now UNLESS you're willing to go breed in episode 13. But that's with Etesian, not me.
