If you have no “Spellbook” Spell Cards in your Graveyard: Reveal 3 “Spellbook” Spell Cards with different names from your Deck, your opponent randomly adds 1 of them to your hand, and shuffle the rest back into your Deck. You can only activate 1 “Spellbook Library of the Crescent” per turn. You cannot activate any Spell Cards the turn you activate this card, except “Spellbook” Spell Cards.
