Well, certainly fast decks would not experience any problems with Hellboros, but slow ones such as Anne may have problems. Short of adding your own 1-2 copies of Hellboros in your deck, there isn't much some decks can do to counter; the matchup isn't looking too prosperous. But as BlitzerSuisei pointed out:

A while ago, the official site went out of their way to point out that only 4% of decks use Hellspin. I rarely see the combo in any tournament decklists I see.
