So, this card is pretty great. It isn't cheap (3-cost, 3 XP), but it ends up reading pretty close to "you draw an additional card each turn" + "you get +1 skill value to a random test each round", and you could do a lot worse than that.
I don't usually consider how many icons are on my assets, but if you are running this in a "regular" Mystic, it may be worth upgrading that Shrivelling to Shrivelling pretty quickly for that extra icon. Generally, I assume you'll use the first every round, and then find tests you are pretty likely to pass to get the cards into your hand.
However, one exceptionally powerful use of this card is with the new signature asset for Norman Withers, Livre d'Eibon. Use Livre d'Eibon to put a skill from your hand on top of your deck, then attach it to the Astronomical Atlas. Then, take a skill test where you can commit that card and get the benefits. When that test ends, you get the skill back, and you can repeat it the next round. Who would like a Deduction or Perception every round? Norman would.
