What to do MGaW to punish second grab

[NTGKOA]

Title says it all, what can i do to punish the second grab with no invulnerability with MGaW? As of now i just spam neutral special and hit 'em with the steak. Very new player, so be gentle.

What can you do against a second ledge grab? (that has no invulnerability)

Chef is good as it counters numerous options.
Dash attack is also good as it can stage spike.
Down aerial (Dair) can spike them straight down I believe.

The most reliable method of punishing a sequential ledgegrab is well spaced dsmash, which will let you keep your distance with the opponent, keep commitment to a minimum, and deal high knockback.

This of course assumes an onstage position. Offstage, a turtle (or even up b) into a probable stage spike can also work.

What can G&W pull off after a ledge trump? I've seen Ike flow into his SJ bair for the kill.
