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.
