Two things came up in a recent game which I'm not sure about.
My first question is whether playing a dupe counts against Fear of Winter's limitation. The rules state that attaching a dupe is done "by simply placing the duplicate under the version already in play." We figured this does not equal "play" or "putting into play", but we'd like to make sure.
The second question I had was whether using the ability of Winter Honor Guard to put it into play from my hand under the control of an opponent does qualify for a "when a character changes control" effect. It's how it was played at the time, but I am having second thoughts, figuring that a card probably maybe needs to be in play first before any change of control can happen.
