Assuming four copies of the card are in your deck and it's early in the game (both should be true if you're using this), the chance that all four will be in the top six is outrageously low, though you can get it even lower with Sensei's Divining Top and the like.
Note that you can also use this to fetch basic lands; in a deck with a lot of colors, that's not at all a bad use for it.
The ability to remove your entire library from the game is remarkably useful. Combine it with Soldevi Digger, say, if you have a particular card you want to repeat endlessly. The best part is that you can still use it to search if you need that instead.

Definitely one of my favorite errata ever: "You must name a card that actually exists in the game of Magic."

@xenocide1337 you misread. It doesn't have to be the seventh card, it has to be any card after the first six. It could be the eighth, ninth, tenth, 200th (if you play this with battle of wits), etc.

Scariest tutor ever made! In certain situations, the best. In many situations, not so good (LOL.) Great to look for something you have 3 of at least... or if you know what most of the top of your library already is.

if used incorrectly, like to fish out a legendary, it may just eat your deck, all of it, esspecialy if it exiles your card in the first six... a little scary I must say.

Shame this ended up banned, because it's SO perfect. It is incredibly powerful, but only if you can get over the fear of playing it. There's nothing more Black than that.

Combo with Laboratory Maniac, give him every sort of protection you can come up with (hexproof, etc.), then cast this card, and have about three counterspells in your hand, because anyone figures out what you have going on, they will do everything they can to stop you, especially if you're naming a card that you "conveniently" forgot to include in your deck.

So good this is what it pretty much reads {B} target player discards a counter spell or loses game.
