Stardust (W/Helmet of Nabu) vs Shuma Gorath

In this little tale, Stardust has possession of Dr. Fates helmet, and has been in possession of it for several years. Let's assume that the dust is an accomplished sorcerer. They battle in neutral space.

How does this play out?

Eh?! Shuma.

Is the helmet powerful enough to prevent ShuGo from dispersing Stardust's atoms across the cosmos or even absorbing them into some container?

PS. not a fan of people wearing other people's "helmets"... unhygienic in the extreme.

Lice win, cause that's what you get when you share hats

Shuma stomps

Um... Shuma. Shuma Gorath.

My bad, I thought a Lord of Order augmented by the Power Cosmic would have a chance here.
