"The Imperial player cannot choose an Agenda set if it contains a card with a listed time period range that does not include the time period of the campaign."
Is this restriction still valid? I thought I read something to the effect that time period restrictions are no longer in effect, but I couldn't find it.
In a mini-campaign, you do not include forced missions from sets in your agenda deck. Since you are already removing the relevant time-period offending card, could you still include the remainder of that set in your deck?
