J'avais vu ceci sur le AMA Phénix Reddit :
Q : In the recent announcement for Children of the Empire, it was discussed revising the duels, specifically to state "initiate a duel". Will the require both characters to be participating in a conflict to initiate a duel? If so, will this also affect cards like Taryu-Jiai which do not require characters to be participating in a conflict.
A : (par Tyler Parrott) : "Taryu-Jiai continues to be the exception. By default, a duel initiated during a conflict requires both characters to be participating."
