This is a good card in campaigns with Wizards of the order, Captive Minds or a keeper of secrets (basically any cultist that will drop doom every phase and gets recurred).
Being Fast certainly helps it, and the removal of doom and banning doom from being placed effectively neutralizes these as threats.
It would also work on Harbinger of Valusia and allow you to deal with that enemy without invoking vengeance.
However at 2 experience it seems a pretty significant investment for such a nuanced card for most campaigns.
So tldr... probably a good card for The Forgotten Age and Circle Undone. Limited benefit elsewhere.
