No lie, I had no clue you could duck one of those attacks.
And I've actually still been getting in by walking and blocking against this.
So yeah. Walk, and block.
Neutral duck to bait one of the overheads. Get him used to having to throw out one of those overheads once in a while. The overheads need to be targeted at a specific part of the screen, and are therefore vulnerable you to running in past them (they don't track).
So even if you eat a few overheads because you are ducking the other attacks and can't react, forcing him to throw out overheads means he needs to respect your ability to run in on him.
**Edit**
Dam guys. I mean, yeah, it was totally funny to watch, but at least indulge him and tell him how to beat it.
