Watching alot of Damosu's play (seems to be the Liz with the most tricks), he seems to be doing alot of 5CC (whiff first hit) after B.Bufu in Thanatos midscreen combos, it works when there isn't too many moves before it, such as off air hits confirms or CH 5CC and such...and then instead of doing j.C ender, going for what seems to be a 2C air reset after the second B.Bufu, examples: (1) (2) (3)
This really doesn't seem to be very effective though since you can just hold tech and block 2C, or am I missing something?
Another possibility is that he's going for whiffing both hits of 5CC and getting a gimmicky backturn mixup, like this which looks really awesome
