Unfortunately, this is probably one of the worst cards in the game and on the same page as Kukri as that it will never ever see anybody play it if they want an optimal deck. It is a shame that this card has one of the most beautiful artworks i have seen but can never find space in any deck that i make.
If they changed it to something like "After this test ends : Add 2 bless tokens to the chaos bag and remove 2 curse tokens from the chaos bag" it would still not see much play, but atleast you could maybe squeeze it in somehow if you are having fun with bless and curse mechanics. We already have Tempt Fate that for fast action give you 3 of both, so maybe this card could have been something similar, but with it not having any icons and requiring you to fail a test so you can get 2 pesky curse tokens out or add just 2 bless ones in if that is what you need is just a complete nonsense!
Very sad, and in a way a complete waste of already limited space that was saved for player cards in The Innsmouth Conspiracy, i wish we have gotten something playable!
