Smash Lord
When GW dairs, first thing to do is not get hit by it. After that, if you're in the right position you can punish with a fireball or a tornado. Possibly a walking dsmash. Maybe a better option would be to short hop over the sideways hitbox, then hit them with an aerial. Sour nair into a combo maybe. In reality though, most often you'll just be avoiding it into a reset.
