Nicol Bolas, Dragon-God

If an ability of a planeswalker exiles cards and another loyalty ability of that planeswalker references the exiled cards, those abilities are linked. If Nicol Bolas gains both abilities from the same planeswalker, the instances he has are similarly linked. Cards exiled by any other abilities Nicol Bolas has (such as his own first loyalty ability) won't be seen by those linked abilities.

After you draw a card as Nicol Bolas's first loyalty ability resolves, the next opponent in turn order (or, if it's somehow an opponent's turn, that opponent) chooses a permanent they control or chooses a card in hand without revealing that card. Then each other opponent in turn order does the same, knowing the choices made before them. Finally, all of the chosen permanents and cards are exiled simultaneously.

If a loyalty ability of a planeswalker references the card it's printed on by name, treat Nicol Bolas's instance of that ability as though it referenced Nicol Bolas, Dragon-God by name instead. For instance, if Ral Zarek is on the battlefield, Nicol Bolas deals the damage if you activate the second ability he gained from Ral.
