If you control a Spellcaster-Type monster: You can reveal 1 other 'Spellbook' card in your hand to target 1 'Spellbook' Normal Spell Card in your Graveyard, except 'Spellbook of the Master'; this card's effect becomes that target's effect. You can only activate 1 'Spellbook of the Master' per turn.
