I think I’ve only seen this once from Luffy.

Is this particularly usable against any move/matchup?

Getting the Soul throw after looks wicked.

I believe you only get the Soul Throw afterwards if it trades. Don’t think it is too useful, probably better just to stick to crouching fierce.

Its not rly consistent, when i do it, its coz i wanted to do chp, but with the buffer it turned into a reflect.

It also depends on the height that your opponent will fly off.
