I was playing yesterday and used Rhaenys's Hill to put my opponent's dead pile into play under my control. One of the cards was Syrio Forel. I won a military challenge with him and, since I controlled him, I triggered his Response and put him into Shadows, still under my control.
And then I realized I had no idea what happened at the end of the phase. On the one hand, he's left play, so he should 'forget' whatever happened to him before that. On the other hand, Rhaenys's Hill creates a lasting effect that should send him back to the dead pile. Since neither of us was sure how to handle it, I thought it fairest to just put him back in my opponent's dead pile at the end of the phase. But the more I think about it, the more I wonder if that was the correct play.
So, if I trigger Syrio's Response under these circumstances does he:
- a) Go to my Shadows area, 'forget' about how he came back from the dead, and stay under my control;
- b) Return to my opponent's dead pile at the end of the phase; or
- c) Go to my opponent's Shadows area (since he owns him and he's leaving play) when the Response is triggered?
Neither of us even thought of © at the time but now I'm thinking it's kind of likely (so triggering the Response would generally be a bad idea).
