MAGIC: THE GATHERING
Reveal a card from your hand. Search your library for a card with the same name as that card, reveal it, put it into your hand, then shuffle your library.
Hellbent - If you have no cards in hand, instead search your library for a card, put it into your hand, then shuffle your library.
Infernal Tutor is the key business spell of Legacy Storm decks. In conjunction with Lion's Eye Diamond, which allows you to get hellbent while providing a bunch of mana, Infernal Tutor does a pretty good imitation of Demonic Tutor. The deck plays a bunch of spells like Dark Ritual in a single turn and then tutors for a Storm spell like Tendrils of Agony or Empty the Warrens.
