Trample
When Iwamori of the Open Fist comes into play, each opponent may put a legendary creature card from his or her hand into play.

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.
