单卡释疑

  如果你指挥官的标识色中不含颜色，则你起动战情室最后一个异能时不需支付生命。

  If your commander has no colors in its color identity, you pay no life to activate War Room's last ability.

  标识色在游戏开始前就已确定，不会在游戏中改变；就算你的指挥官处于不公开区域（比如手牌或者牌库），或有效应改变了你指挥官的颜色也是一样。

  Color identity is set before the game begins and doesn't change during the game, even if your commander is in a hidden zone (like the hand or library) or an effect changes your commander's color.

  如果你没有指挥官，则根本不能起动战情室的最后一个异能。

  If you don't have a commander, you can't activate War Room's last ability at all.
