Book of Eclipse

Book of Eclipse was originally introduced to the Yu-Gi-Oh! Trading Card Game in the 2011 set Storm of Ragnarok. Designed as a strategic spell card, it was crafted to provide players with a powerful defensive tool capable of flipping all face-up monsters on the field face-down, effectively disrupting an opponent's momentum or preparing the board for a tactical shift. The card reflects the game's long-standing mechanical focus on position-based disruption, serving as a versatile alternative to more permanent removal effects by prioritizing temporary control.

The version from Battles of Legend: Monstrous Revenge, numbered BLMR-EN090, features the highly sought-after Secret Rare treatment. This reprint highlights the card's enduring relevance in competitive play, as its ability to force monsters into face-down defense position remains a relevant counter to modern decks that rely heavily on monster effects. By reissuing such a functional classic in a premium rarity, the designers acknowledged the card's historical impact while providing a visually elevated aesthetic for collectors and tournament players alike.
