Jet Wyvern Help

Hey everyone,

My wife just picked up Jet Wyvern (she absolutely loves the way it looks), but so far it's pretty "meh", even vs opposite spin.  Any suggestions on improving it's performance?

For future reference, if you're asking about combo suggestions, please use the linked thread instead of making a new thread just to ask. Thank you.
