What tomes would benefit from being reloaded? Assuming you can take Seeker XP 1.
De Vermis Mysteriis -- likes being returned; get rid of that pesky Doom! (2)
Esoteric Atlas -- both versions
Forbidden Tome -- if you somehow mess up and take the 5th secret without 10 cards in hand.
Grimm's Fairy Tales -- assuming you are Minh (or Rex).
Old Book of Lore (3)
Scroll of Prophecies (0)
Scroll of Secrets -- All vesions, if you can take (1) for the upgrade.
The Necronomicon -- yes!
The King in Yellow is sadly immune to this card, but I am not sure if you could use it on either version of The Necronomicon and just live with a hand size of 7? I expect the riule of not being able to discard or remove Weaknesses other than by their card effects would hold sway.
