Other than obviously Stephen Strange, few occultist/sorcerer heroes have had long-running series. Even Stephen Strange seems to have never lasted into triple digits in any of his solo series.
Hellstorm/Hellstrom has managed even fewer issues in any given volume.
This situation seems slightly the opposite case at other publishers. John Constantine lasted three hundred issues in the longest respective volume, while even Arion lasted approximately three years. Tim Hunter and Doctor Fate lasted the middle amongst those lengths.
Outside of the obvious exceptions like Dracula, Werewolf, Strange, and Ghost Rider, Marvel historically hasn't done supernatural well. It almost seems that there's some unwritten rule for science to be the dominant force at Marvel.
