When Borderland Explorer enters the battlefield, each player may discard a card. Each player who discarded a card this way may search his or her library for a basic land card, reveal it, put it into his or her hand, then shuffle his or her library.

Players decide whether or not they’re discarding a card in turn order. Each player will know if previous players are discarding, but not what they are discarding. All cards to be discarded are set aside, then revealed and discarded simultaneously. Similarly, all basic land cards searched for are set aside, then revealed simultaneously.
