Printing this card was a mistake, it's very overpowered. By itself, this card theoretically allows a player to have about half of a 30 card deck in their hand, and that's without looking at Laboratory Assistant (multiples with Charisma), Arcane Enlightenment, or myriad cards.
So what's wrong with that? Well, once a huge chunk of an investigator's deck is either in their hand or played on the table in the form of assets, there are few remaining cards in the deck, allowing powerful card draw tools like Mr. "Rook", Cryptic Research, or The Necronomicon to quickly cycle through what's left and play power cards repeatedly. The 1 horror penalty for reshuffling the deck can be dealt with by soaking on an ally and replaying it (Laboratory Assistant or Mr. "Rook" are perfect for this).
The ridiculously overpowered The Necronomicon is a prime candidate for this type of abuse, but there are many other cards that become overpowered when played repeatedly, 3x Three Aces which also fuels the draw/cycle engine with resources and cards while auto-passing any test, Segment of Onyx/Pendant of the Queen, Extensive Research (0 cost with this strategy), or Ancient Stone are other possible examples of strategies that subvert the chaos bag by being testless ways of solving problems presented in Arkham Horror. Even merely good level 0 cards such as Shortcut (take repeated extra move actions), Mind over Matter (make any Fight or Agility test an Intellect test) or Deduction (pick up clues twice as fast or three times as fast with Deduction) become degenerate.
