It's like any situation where you read a backdash then, and they can't in the corner which is where this is primarily used, either delay a b2 to catch them or chase them down with a dash or instant air dash.
You do realise that move is meant to be used in the corner, right? You can also reset an opponent at +6 near the end of a combo very suddenly before they realise you haven't went for an autopilot combo.
You use Amazonian smash to deny your opponent a wake-up while leaving them in your b2 range at disadvantage, once they respect that they cannot wake up you can truly mix them up after lasso grab with F3 cross-ups, B2/33 mix-ups and blockstrings, with occasional Amazonian smashes to keep the opponent in check. MB Amazonian smash also launches.
