Yeah, sorry, just realized that 5B's too slow (still used to punishing 623B on IB with Ragna that way). Oh yeah,TK Swallow Moon Bubble oki is a great way to bait Ashura and Daifunka on wake-up as long as you don't go for Instant Overhead. Just like everyone has been saying, IB his pressure, He'll crumble like Litchi.
EDIT: Just went to training mode, You can punish 623B on IB with 5C if you're close enough too.
