  Each face of a double-faced card has its own set of characteristics: name, types, subtypes, abilities, and so on. While a double-faced card is on the battlefield, consider only the characteristics of the face that’s currently up. The other set of characteristics is ignored.

  If Nicol Bolas leaves the battlefield after his creature face’s activated ability has been activated but before it resolves, the card remains in whichever zone it moves to. It won’t be exiled or return transformed.

  When Nicol Bolas’s enters-the-battlefield triggered ability resolves, first the next opponent in turn order (or, if it’s an opponent’s turn, that opponent) chooses a card in their 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.
