This seems really good for Gloria Goldberg. "Look at the top 4 cards of the encounter deck." - period. She gets to pull 5 and use her ability to filter a really bad card. Then perform the token draw and possibly place the rest back as needed.
Look at the top 4 cards of the encounter deck. Reveal a random token from the chaos bag. If it has a , , , , or symbol, shuffle those cards into the encounter deck. Otherwise, return them to the top of encounter deck in any order.
This is a flavorful card, but I'm not sure how effective it is outside of Jacqueline or another chaos bag manipulation Mystic. It's also of less use in Solo, since you can't parcel out the cards to the investigators best suited to withstand them, although knowing what the next 4 Mythos Phases are going to spit out isn't nothing (always assuming the Act or Agenda doesn't reshuffle the Encounter Deck before you get to the 4th Round).
It's most similar to First Watch, with -1 cost, requires an action, has a "bad stuff token" test, and always looks at 4 cards. In 4-player, First Watch is much better, in 2-player, Parallel Fates lets you pick between investigators for 2 turns, so it probably edges the card out.
Gloria Goldberg might like this, since it synergies with her ability, although she'll need chaos bag support to make it really work. All in all, this might have a few too many moving pieces to be a mainstay, and I'd be happier if it was Fast or didn't have the token pull, but maybe future cards will make it more reliable.
