Daisy Falls Down the Rabbit Hole

Self-made deck for a 4 player campaign where Daisy is the primary cluever. Deck was built around upgrading cards quickly using Down the Rabbit Hole. In addition, the deck was built with Miskatonic Archaeology Funding in mind, which is why there are 3 allies in the deck. Granted, the Archaeology Funding is not an upgrade, so you'll have to pay an additional XP for it.

The deck is built around maxing your books stat quickly.

For allies, the primary ally is Dr. Milan Christopher for the passive boost and the income generation. Jeremiah Kirby provides a passive boost to books while also giving you a one time card draw that could net you 5 cards. The majority of the cards in the deck have an even cost, so choosing 'even' with Jeremiah has netted me on average 3 or 4 cards per use. Whitton Greene can give the stat boost and some card draw as well. You could also consider adding the Research Librarian if you plan to get The Necronomicon, though that's not an upgrade so you'll pay an additional XP for it. But with the savings you get from other upgrades, you may be able to swing for it.

One downside to the Miskatonic Archaeology Funding is that it limits how you can distribute damage to your allies. This isn't a Leo Anderson expedition, so Miskatonic University wants their faculty back. You'll want to consider other alternatives to damage management (healing with Medical Texts or Painkillers).

The upgrades are where this deck shines. You can upgrade Archive of Conduits and Archaic Glyphs into some power cards. I prefer the Guiding Stones version of the Archaic Glyphs, which you can combine with an upgraded Deduction to try and clean off a big clue location in a single try. One downside to these upgrades are that they are no longer tomes, but that is fine because you'll dedicate your free book action to Dream Diary, Old Book of Lore, and the Encyclopedia.

The major cons for this deck are the damage management (already mentioned above) and the card cost. One thing to keep in mind is that the Emergency Cache is an upgradable card, so you can get the upgraded version for some extra resources or card draw.
