Whenever you cast a spell, you may counter it. If you do, target opponent cuts your library, then you reveal the top card of your library. If it's a land, put it onto the battlefield under your control, otherwise cast it without paying its mana cost.
(To cut a pile of cards, put any number of cards from the top to the bottom of the pile, without looking at them or changing their order.)
