- You do not search for a specific card. Rather, you just look at the top 3 cards of your deck, draw the one you like most, and shuffle the rest back into your deck.

Item. Tome.

Exhaust Old Book of Lore: Choose an investigator at your location. That investigator searches the top 3 cards of his or her deck for a card, draws it, and shuffles the remaining cards into his or her deck.

- Old Book of Lore (3) Where the Gods Dwell #279

Just finished our first game, and this was a standout card in my deck. Daisy Walker gets a free action to use tomes, so this is a free card draw every turn (doubling your basic rate of drawing) and it's filtered, meaning you won't ever draw a Weakness at the wrong moment on your turn. Plus, of course, it turns on her ability.

A fringe benefit is that it gives a shuffle (not sure how useful this will ultimately be, but gives a nice combo with cards like scrying to shuffle your deck if you don't like 2 of the 3 you see), and also note that it isn't unique. Sure, I can't often see having two, as there are likely more crucial tomes to take (especially over time as we get new cards), but extra card draw for your colleague could be nice.

I mean... what's not to love? I can't ever see Daisy not running 2 of these, and in fact I'm going to be packing Research Librarian as a two of to get it to my hand as quick as possible.

Just to underline how powerful this card is in a Daisy Walker deck. There is an interesting note on how card draw and randomized decks work.

Whenever you draw a card from a randomized deck, say a deck of 20 cards, there is a 1 in 20 chance to draw any one particular card. In an environment where you draw cards regularly, there is a 100% chance that you'll draw each card in the deck eventually. This means that even though there is a, say, 1 in 20 chance of seeing your weakness on each draw, there is a 100% chance that you'll draw it eventually. To be more particular, there is a 100% chance that you'll draw it at the point that you find it in your deck, say for example if it's the 4th card from the top, then there is a 100% chance you'll draw it once you've drawn 4 cards.

Old Book of Lore has a really funny interaction here. Whenever you shuffle your deck you refresh each cards randomized location, so long as you shuffle every turn the cards will have a new randomized location every turn! This has the effect of changing when you draw your weakness from "100% once you've drawn 4 cards" to "100% so long as the Weakness is the topmost card after a shuffle."

.

TL:DR. So long as you use Old Book of Lore every turn, the chance to draw a weakness is literally "1 in however many cards are in your deck". The only Weaknesses will be those that you're unlucky enough to top-deck after a shuffle.

I.E, Daisy Walker is very unlikely to draw her weaknesses with this card in play.

BTW the same is true for Eureka! and No Stone Unturned but neither of those can minimize weakness odds indefinitely..

Solid Mandy tech. Given that she can use this to see the top 6 cards in your deck, she can use this to fish for her weakness / free clues relatively cheaply. As most searches cost an action and resources, it seems worthwhile to pay an action for the search.
