I'm a little surprised this card hasn't received better, or I guess more, fanfare. This is essentially 3 resources for 4 Premonitions which is incredibly powerful. The big drawback is that you have to decide the action you're going to take in advance rather than playing Premonition and deciding what action would be best to use the sealed token on. Generally speaking though, you'd only use a premonition on an important skill test (i.e. where the stakes are high), but the same is true here since you only get 4 secrets (but that is rechargeable through a number of cards, Enraptured in and Truth from Fiction and Eldritch Sophist if you've got access to ).
The ability to know EXACTLY what token you'll be resolving is strong, more so if you have anything that can draw multiple tokens (McBride, Jacqueline). If you're going to be just a little bit short, you now know if you need to commit a card from your hand that you were hoping to play. But obviously, that's just some useful knowledge that helps keep you from over or under committing. The real strength of the card is when you're committing skills to the test.
Unfortunately, most skills don't really need this. Enraptured will simply replace it's own secret (though you can use it to charge a spell instead), while skills like Prophesy and Torrent of Power are generally strong enough that it'd be a bit of a wasted use. It doesn't work with Defiance since you have to pick a symbol before you reveal, and even though it does combo with Defiance lvl 2, I'm not sure how useful that would be. Jacqueline's favorite augury is a great target since the effect is quite powerful, but you already have good odds of getting that to trigger so long as you're drawing multiple tokens.
Given this, probably the best thing about the card is it's lvl 0 rank, allowing it to be taken in off class s, Dunwich gators and anyone who's versatile enough. In faction it's a good little luxury/tool, but off class it's quite powerful. s like Silas Marsh and "Ashcan" Pete would appreciate it. s with Shotguns would like it, especially Zoey Samaras and the upcoming Sister Mary (which is exactly how I intend to play the nun with a gun). And Dexter Drake and especially Sefina Rousseau can abuse the crap out of all those delicious skills.
Aside from it's use in solo (which is good if a tad expensive), it's really going to shine in multiplayer where you'll be everyone's best friend. Remember that other investigators at your location can get in on the fun and commit their own cards to compound the effects. You could even double up those tokens with Take Heart and Self-Sacrifice.
