This artifact is a must for most undead decks. Being a Greyhawk artifact, it can be attached to many of the best undead champions and has a nice +4 bonus for any champion you attach it to. The best feature of the artifact though, is its protection of all of your undead champions from cards of mass destruction such as the events Treasure (130/4th), Water Hunters (276/3rd), and The Avatar (20/1st-chase), all of which play havoc with your average undead deck. This card also protects your undead champions and their attachments from the most powerful card in the game - Wish (384/4th).
Note that these protections only work for cards in the pool. If you have your best undead champion involved in a battle with a little level 3 adventurer who wants to wish you to the discard pile, you're out of luck. Attaching this to a low level undead champion you don't necessarily want to involve in battle is a good strategy. For example, if you attach the book to the Lich Conclave (265/4th), you bring the champion's level up to 8. This puts him out of Death Spell (377/4th) range and gives you a champion who can just sit in your pool and toss wizard spells around while he protects your other undead.
The Book of the Dead was last in the possession of Iuz the Evil during the height of the Greyhawk Wars. Rumor says it was stolen from him by a band of thieves and is now hidden in the Bandit Kingdoms.
