Name a card. Exile the top six cards of your library, then reveal cards from the top of your library until you reveal the named card. Put that card into your hand and exile all other cards revealed this way.

There is no way to make this card affect your opponent. It affects "you", and "you" means the controller of the spell. It has no targets.

You must name a card that actually exists in the game of Magic.

You don't name a card until Demonic Consultation resolves.

If you don't reveal the named card (perhaps because it was in the top six cards of your library), you'll end up exiling your entire library. You don't lose the game at that point, but will lose the next time you're instructed to draw a card.
