This is probably the wrong fourum as it's more a "bad beat" story .. but there is a question anyway
The basic question is whether the control of Steelshanks Reserves can change during the challenges phase and if so, presumubly the control returns immediatelty to the first player
Assuming control does change - the character would get a power on it each time the control flips (if I have played In Ramsay's Name)
I'll post the scenario seperately ...
Steelshanks Reserves
During the challenge phase, the active player gains control of Steelshanks' Reserves.
In Ramsay's Name
Until the end of the phase, each time a House Bolton character changes control, that character claims 1 power
Other cards involved (in the scenario)
Roose Bolton
Roose Bolton does not kneel to attack during Intrigue challenges. Response: After you win a challenge in which Roose Bolton participated, all players take control of each character they own currently in play.
Winterfell Honour Guard
You may put Winterfell Honor Guard into play from your hand, under the control of any opponent. After that opponent wins a challenge in which Winterfell Honor Guard participated, take control of Winterfell Honor Guard.
