Here are some of the issues I've hit over the past week:
Kraznyz Mo Nakloz vs events that become attachments ala Risen From The Sea: Can the Targ player just take them, or are they immune since they have no printed cost?
One of my guys gets reduced to 0 by Flame-Kissed while Threat From the North is revealed. Is he put into the dead pile or the discard pile?
Plot effect resolution:
I reveal Valar Morghulis and my opponent reveals Wildfire Assault. He chooses to resolve his plot first, kills some dudes, and then puts his Meera Reed into shadows as a response to his dudes dying before Valar goes off. Is this a legal play, or is there no opportunity for Meera's response?
I have the new Damphair on the board when a Valar happens. I believe that cards stay on the table and moribund until the plots fully resolve, including opportunities for responses such as the one Damphair would have after becoming an agenda. However, if he is still moribund, he is not an agenda yet, so you cannot draw any cards for any saves you do for other characters during this Valar. Is this correct?
My opponent reveals Threat From the North and I reveal Valar Morghulis. I have Maester Wendamyr on the table. Does he stay on the table and moribund through the Valar, allowing me to save someone with him before he is discarded, or is he gone before I can use him?
