Official rulings

One official ruling applies to Cavern Whisperer.

  • As the triggered ability resolves, first the next opponent in turn order (or, if it’s an opponent’s turn, the opponent whose turn it is) chooses a card in hand without revealing it, then each other opponent in turn order does the same. Then all the chosen cards are discarded at the same time.
