Extra Info

• Card Rules: Rulings powered by The Netrep API. When you activate 'Book of Moon' during the Battle Step to flip your defending monster into face-down Defense Position, the attack resolves as normal. No replay occurs because the possible attack targets on your side of the field did not change. When you activate 'Book of Moon' during the Battle Step to flip an attacking monster into face-down Defense Position, the attack stops. No replay is triggered. The attacking monster cannot change its battle position in Main Phase 2, because it is still considered to have declared an attack. (So it cannot be Flip Summoned in Main Phase 2.) If you are attacking, and you chain 'Book of Moon' to your opponent's 'Mirror Force' to flip one of your monsters face-down, that monster is not destroyed by 'Mirror Force'. If you chain 'Book of Moon' to 'Magic Cylinder', 'Ring of Destruction', or 'Trap Hole' to flip the target of any of those cards face-down, the card's effect disappears. (See 'Activation & Targeting Eligibility' in the Advanced FAQ.) If you use 'Book of Moon' on a monster that had its ATK doubled with 'Limiter Removal', the monster is not destroyed at the end of the turn. If you chain 'Book of Moon' to 'Bottomless Trap Hole', the now face-down monster will not be destroyed by 'Bottomless Trap Hole', but any other appropriate monsters Summoned at the same time will still be destroyed. If you use 'Book of Moon' on 'Dream Clown', 'Dream Clown''s effect is not activated. If you chain 'Book of Moon' to the activation of a Flip Effect Monster's effect, such as 'Fiber Jar', 'Book of Moon' flips the monster face-down again, but the Flip Effect still resolves as normal. You cannot flip a Monster Token face-down because Monster Tokens are always face-up. You cannot activate 'Book of Moon' while 'Light of Intervention' is active. [Re: 3-Hump Lacooda] If your opponent chains 'Ring of Destruction' or 'Book of Moon' to the activation of '3-Hump Lacooda''s effect, the effect is not negated. [Re: Adhesion Trap Hole] If a monster affected by 'Adhesion Trap Hole' is flipped face-down (with 'Book of Moon', etc.), 'Adhesion Trap Hole''s effect disappears and the monster's ATK is back to normal. [Re: Allure Queen LV3] If 'Book of Moon' is chained to the activation of 'Allure Queen LV3's' effect to turn the 'Allure Queen' face-down, then the monster that was targeted is destroyed. It cannot be equipped to a face-down monster. [Re: Ancient Gear Castle] For 'Ancient Gear Castle', 'Set' means to Set from the hand. It does not include using 'Book of Moon' or 'Guardian Sphinx' to flip a monster face-down, or Special Summoning a monster in face-down Defense Position with 'Cyber Jar' or 'The Shallow Grave'. [Re: Armor Exe] If you Summon 'Armor Exe', flip it face-down with 'Book of Moon', and flip it face-up with 'Book of Taiyou', it CAN attack because its non-attack effect was reset and because flipping it face-up with 'Book of Taiyou' was NOT a Flip Summon. [Re: Aussa the Earth Charmer] If 'Book of Moon' is chained to the Flip Effect of a 'Charmer' to flip the target monster face-down, the effect of the 'Charmer' disappears. [Re: Big Shield Gardna] If 'Big Shield Gardna' is targeted with a Spell Card, you may chain 'Book of Moon' to flip it face-down, then it can negate the Spell Card and will flip back to face-up Defense Position. [Re: Bottomless Trap Hole] If the opponent Summons a monster, then you activate 'Bottomless Trap Hole', and the opponent chains 'Book of Moon' to flip the Summoned monster face-down, it is not removed from play by the effect of 'Bottomless Trap Hole'. [Re: Burst Stream of Destruction] If you activate 'Burst Stream of Destruction', and the 'Blue-Eyes White Dragon' is removed from the field with 'Interdimensional Matter Transporter' or 'Compulsory Evacuation Device', or flipped face-down with 'Book of Moon', or destroyed by 'Ring of Destruction', 'Burst Stream of Destruction''s effect still resolves. [Re: Chain Disappearance] If your opponent activates 'Chain Disappearance' and you chain 'Ring of Destruction', 'Ring of Destruction' resolves first and destroys the monster and sends it to the Graveyard, and there is no monster of the same name so no cards are removed from play for the effect of 'Chain Disappearance'. If you chain 'Book of Moon', the monster will be face-down, so no cards are removed from play for the effect of 'Chain Disappearance'. [Re: Chaos Sorcerer] If you select a face-up monster with 'Chaos Sorcerer''s effect, and your opponent chains 'Book of Moon' to flip the monster face-down, then 'Chaos Sorcerer''s effect disappears. But even if 'Chaos Sorcerer''s effect disappears, its effect was activated so it cannot attack or activate its effect again. [Re: Curse of Anubis] If 'Book of Moon' is chained to 'Curse of Anubis' to flip a monster face-down, the effect of 'Curse of Anubis' is not applied to the monster that was flipped face-down. [Re: Cyber Laser Dragon] If 'Book of Moon' is chained to 'Cyber Laser Dragon's' effect to turn either the targeted monster or 'Cyber Laser Dragon' face-down, its effect will not resolve because both monsters' ATK / DEF values can no longer be compared. [Re: D.D.M. - Different Dimension Master] If the opponent chains 'Book of Moon' to his effect and flips 'D.D.M. - Different Dimension Master' face-down, you still resolve his effect. [Re: Dark Magic Attack] If you activate 'Dark Magic Attack', and the 'Dark Magician' is removed from the field with 'Interdimensional Matter Transporter' or 'Compulsory Evacuation Device', or flipped face-down with 'Book of Moon', or destroyed by 'Ring of Destruction', 'Dark Magic Attack''s effect still resolves. [Re: Dark Paladin] If you activate 'Dark Paladin''s Spell-negating effect, and your opponent chains 'Book of Moon' to flip 'Dark Paladin' face-down, the Spell Card is still negated even though 'Dark Paladin' is face-down. [Re: Desert Sunlight] If you have a face-up Flip Effect monster, you can activate 'Desert Sunlight', and chain 'Book of Moon', another 'Desert Sunlight', and another 'Book of Moon'. When the chain resolves, you will flip the monster down, then up, then down, then back up. The Flip Effect activates twice, and they wait to create a new chain after the current one resolves. For example, if the Flip Effect monster is 'Morphing Jar', its effect will activate twice in a chain, as Chain Link 1 and Chain Link 2, they resolve in reverse order, and both players will discard and draw 5 cards, then discard and draw 5 cards again. [Re: Doomcaliber Knight] Even if 'Book of Moon', etc., is chained to 'Doomcaliber Knight's' effect and flips the Effect Monster face-down, the Effect Monster's effect is still negated by 'Doomcaliber Knight' and it is still destroyed. [Re: Double Snare] You can only destroy face-up cards with the effect of 'Double Snare'. The opponent may chain 'Book of Moon' to your 'Double Snare' to flip his / her monster face-down, and it will not be destroyed. [Re: Enemy Controller] If you activate either of 'Enemy Controller''s effects, and your opponent chains 'Book of Moon' to flip the target monster face-down, its targeting conditions are no longer correct when 'Enemy Controller' resolves and 'Enemy Controller''s effect disappears. [Re: Enemy Controller] If you take control of your opponent's monster with 'Enemy Controller', and then the monster is flipped face-down with 'Book of Moon', control of the monster is still returned to the opponent (the original controller) during the End Phase. [Re: Eria the Water Charmer] If 'Book of Moon' is chained to the Flip Effect of a 'Charmer' to flip the target monster face-down, the effect of the 'Charmer' disappears. [Re: Giant Kozaky] If 'Giant Kozaky' is destroyed while face-down, then its effect that inflicts damage is not activated. If 'Giant Kozaky' is face-up on the field and is targeted by 'Tribute to the Doomed', and you chain 'Book of Moon' so that 'Giant Kozaky' is face-down when destroyed by 'Tribute to the Doomed', there is no damage. [Re: Gorgon's Eye] If 'Gorgon's Eye' is active and you activate a monster effect, and 'Book of Moon' is chained to flip the monster into Defense Position, the monster's effect is still applied and is not negated by Gorgon's Eye because it was activated properly. [Re: Grave Ohja] If 'Grave Ohja' is attacked, and you activate 'Book of Moon' to flip another monster on your side of the field face-down, 'Grave Ohja' has already been selected as the attack target so the attack proceeds as normal. [Re: Hiita the Fire Charmer] If 'Book of Moon' is chained to the Flip Effect of a 'Charmer' to flip the target monster face-down, the effect of the 'Charmer' disappears. [Re: Huge Revolution] When your opponent chains 'Book of Moon' to your 'Huge Revolution' and flips 1 of the 3 monsters face-down, 'Huge Revolution' has already been activated correctly so the effect of 'Huge Revolution' resolves. [Re: Legacy Hunter] The monster that 'Legacy Hunter' attacks must be face-down at the start of the Damage Step for 'Legacy Hunter's' effect to activate. So if 'Legacy Hunter' attacks a face-down Defense Position monster and your opponent activates 'Ceasefire' to flip the monster face-up, 'Legacy Hunter's' effect is NOT applied. Also, if 'Legacy Hunter' attacks a face-up monster and 'Book of Moon' flips it face-down, 'Legacy Hunter's' effect DOES apply. [Re: Light of Intervention] While this card is on the field you cannot flip a monster face-down with 'Book of Moon', 'Darkness Approaches', etc. [Re: Magical Scientist] If the Fusion Monster is flipped face-down with 'Book of Moon', or removed from play with 'Dimensionhole' or 'Interdimensional Matter Transporter' or 'Different Dimension Gate', the effect is reset and the Fusion Monster does not go back to the Extra Deck, and is not prohibited from attacking your opponent's Life Points directly.
