Draw four cards, then put two cards from your hand on top of your library in any order.

Niche card draw for control and tempo decks, but the net effect of drawing only two cards makes it substantially worse than established alternatives like Counterspell or Mystic Remand in most shells. The library manipulation is rarely relevant enough to justify the awkward tempo loss.
