When The Dark Queen enters the battlefield, if you cast it from your hand, choose a card type other than land. Search target player's library for any number of cards of the chosen type and exile them. That player chooses a card type other than land, searches your library for any number of cards of that type, and exiles them. Shuffle both player's libraries afterward.
Original does not mention shuffling; I don't know if this card should include or exclude shuffling.
