Ok... so here is another rules question:
The text on Khal dorgo (core) states:
Response: After you win a challenge, put Khal Drogo into play from your hand. At the end of the phase, return Khal Drogo to his owner's hand.
So we were wondering, what if he is already on the table and a challenge is won. Could we trigger the response? Sure, we cant put him into play, he's already in play. But, could we return him to our hand at the end of the phase?
We are thinking of it in terms of a strange mechanic to eventually bring back attachments via a location card in play.
