On some cards I've read "Place to one side" and I couldn't understand does that mean that it is removed? If said for a building does it mean that it is destroyed or has a different meaning? I couldn't find that in the rules.
The card that baffled me was Bloody Stupid Johnson: "Roll the die. If the City Area card of the same value is in play then that card is placed to one side. The owner of the card must also remove one of his minions from the same area as the card."
How is this played out?
