Oh boy... there are bad cards, there are laughably bad cards, there's Flute of the Outer Gods, then there's this absolute hunk of junk. My goodness, what a terrible waste. Let me point some things out...
You'll need dedicated support curse token bag manipulation to make this card even close to being viable. That is going to almost certainly mean help from a red character running the absolutely overpowered Spirit of Humanity. Nothing else is going to come close in multiplayer in keeping the chaos bag stocked full of tokens. Even so.... good luck ever getting 5 charges on this card purely from curse tokens that ONLY you can pull. You're lucky to pull 5 curse tokens in an entire mission with a chaos bag filled with 10 at most times. So even if you DO manage to get 5 charges on it, and you manage to ignore one single encounter card, what have you invested...
You've struggled through the untranslated grimoire, which is just a dead card in your deck.
You've spent a whopping 4 xp to purchase this card.
You've had to find this card early in the mission so that you have a prayer of getting 5 secrets.
You have a precious hand slot taken up for the entirety of the mission.
You make all this investment for a card, that if drawn in the last half or so of a mission, is completely dead. There's no point trying to play this card when you only have a few turns left. It's only viable if found and played early.
All that to ignore MAYBE.... and I say MAAAAAAYBE 1-2 encounter cards (and draw 2 cards).
My goodness. You can make it your life mission to manipulate secrets via Eldritch Sophist, Ariadne's Twine, Favor of the Moon, etc... but my god. You're devoting all this effort simply to cancel a couple encounter cards with a big fat maybe attached.
There's no comparison to say, A Watchful Peace. Absolutely none. Cheaper to play. Far easier to play. No silly untranslated hoop to jump through. No hand slot to take up, and simply 5 bless tokens from anywhere.
I've run a campaign with a dedicated support curse token, Spirit of Humanity Agnes Baker, keeping the bag full of curse tokens, and i proc'd this card precisely zero times. Give it a wide miss.
A simply taboo fix that is DESPERATELY needed is to proc the curse tokens from any investigator at your location.
