When Iwamori's triggered ability resolves, first the player whose turn it is (if that player is an opponent) may choose a legendary creature card in hand without revealing it, then each other opponent in turn order may do the same, then all chosen cards are put onto the battlefield at the same time.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
