Once per turn: You can discard 1 "Spellbook" Spell Card to target 1 Spellcaster-Type monster in your Graveyard; add that target to your hand.
You can mill your Exodia monsters into the graveyard with cards like Needle Bug nest or That Grass Looks Greener, and then use this monster’s effect to retrieve them.
Here are some Spellbook spell cards that support the Prophecy Archetype and Spellcasters in general. You can discard them with Charioteer of Prophecy’s effect to retrieve a Spellcaster-type monster from your graveyard.
