The card seems incredibly powerful.
First advantage which can be easily overlooked: it can be triggered for any skill test performed by any investigator no matter which location you are in. It gives the card an extreme usability.
Second: it can negate autofail. Not completely, because if you've committed Deduction or if you're trying to discard Mihn's weakness the effect of the committed skills is worn off, but if it is, for instance, a Pilfer attempt or something like Deciphered Reality... I also tend to be a magnet for autofails when I'm using Act of Desperation... It can save the day and a great chunk of tempo for the team.
Where the card seems the best for me, is when one of the team is playing from cursed tokens while all other teammates are not really ready for it. If that's the case, this card looks like a good option in the list of the top priority upgrades.
