This match-up is very spacing and momentum based. You've got tools to keep her out and she's got tools to get in and stay in if you're not careful. What you want to focus on is not being so predictable about your approach. Comet Cannon, 6A, and a well placed Corona Upper will stuff it. Try your best to mix-up your spacing pokes. If you use 5B too much, they'll 3C under it and punish you with a combo leading into 4-5k+ and Corner oki. Use 5C sparingly, if you get a counter hit you can follow up with Hell's Fang and have her stuck in the corner right where you want to keep her. 6A clashes with her j.2c so don't go relying on that to AA her every time. If you see that bushy tail coming down, use C Inferno Divider and if it hits once, then try to follow up with dash 5B to double BE combo since opponents can't tech out of CH C ID till they hit the ground. Don't approach from the air predictably. Space Counter Fatals go up to 9k (I may be exaggerating but I heard that they go past 5k), need I say anymore?
