Shago Fwd. Dash: 36 (also totally invincible from 11 to 24),
Shago Backdash: 41 (also totally invincible from 13 to 23)
(pardon the difference in slang)
In order to reliably combo from Lv4 Battery Ender, Shago needs meter available (at least 1S, ideally 1bar and 1S), and it is much easier (and beneficial) with INSX. Without INSX, I wouldn’t worry about comboing post-ender outside of the corner, as the timing is super tight and if you drop it, you’ve wasted time you could’ve used to set up your next offensive play. That said, try this:
[combo>L4]
INSX>Battery Ender>st.HK x Sg.FB x EX Divekick>
[continuecombo]
I didn’t catch if you mentioned it already, but Surges can be cancelled into EX moves. This gives us an incredibly reliable recap with Sg.FBxEX Divekick, and if they let the EX Dive through, you can go straight to ender, as that was their break-point. The best part is the INSX starter to the above sequence though, as INSX>Battery followups are discounted by our Tether. Feel free to use this combo opportunity to spend as much of your opponents meter as possible. Just be ready to counterbreak if they seem like they don’t wanna play along - lots of EX Linkers makes for lots of easy CB baits.
I’ve got a textual breakdown of how to set-up the GTFO Mixup (which is what I think of the stepkick mixup as). I’ll post that later though. It’s just an explanation of one of the above-posted videos.
