  If a player controls no permanents destroyed this way, that player reveals no cards from their library and doesn’t shuffle it.

  If an artifact or creature is targeted but not destroyed (perhaps because it gained indestructible or became an illegal target), it doesn’t count as one of the artifacts or creatures destroyed this way. An artifact or creature that’s destroyed but put into a zone other than a graveyard (such as a player’s commander in the Commander variant) does count.

  While revealing cards, a player stops as soon as they reveal a card that’s an artifact or a creature (or both). That player doesn’t choose one type.

  If a player’s library no longer contains an artifact or creature card when instructed to reveal cards, that player reveals the entire library, exiles no cards, and then shuffles it.

  All of the exiled cards are put onto the battlefield at the same time.
