If Player A has a character in play that has an attachment on it, and Player B plays a card that allows him to take control of the character, does Player B also gain control of the attachment?
We could not find where card control was explicitly addressed in the rulebook (other than generically). This caused a debate recently when Player B took control of Player A's card + attachment and the attachment had an effect that sent it and the character to a domain as resources upon destruction rather than to the discard pile. Player B killed the creature and then Player A claimed that the two cards actually went to his domain because he actually still controlled the Attachment despite the fact that Player B controlled the character it was attached to.
Any insight on this is greatly appreciated. Also, is there a comprehensive rules doc somewhere that we can use to answer detailed questions like this?
