When you've both focused some cards in a duel, are all focused cards revealed simultaneously, or are they focused one at a time?
How are focused cards revealed?
A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
After a player strikes, all focused cards are revealed simultaneously. Then Focus Effects resolve one after the other, in an order chosen by the active player.
Challenges and duels, Duels: "E: Both players reveal (turn face up) all cards in their focusing area. F: Focus Effects resolve. All Focus Effect traits on focused cards resolve, one after the other, in an order chosen by the active player."
