Search your library for up to four land cards with different names and reveal them. An opponent chooses two of those cards. Put the chosen cards into your graveyard and the rest into your hand. Then shuffle.
You may reveal fewer than four land cards if you like. If you reveal one or two cards, those cards are put into your graveyard. If you reveal three cards, an opponent will choose two of those cards and you’ll put them into your graveyard; the remaining revealed card is put into your hand.
