After the imperial cicle some "sacred cows" are in their way to be replaced cause they loosed some power with new releases, and still, other cards are becoming even more relevant..
Assassination: Vital in core set, every deck used to run at least 2, but now with stronger dishonor decks and the game slower, my impression is it will loose some slots in many decks, and with more diversity of good 2 cost targets it can become less effective.
Court Games: This is a card I don't expect to see less use soon, in core set it was more a "I'll run 3X cause there's nothing better with 0 cost". But with the meta right now is difficult to take it off, either to protect your honor, lock high glory chars or to gain some political skills.
Policy Debate: Winner of the most hated contest, righ now it seem a little OP, but with several releases I believe we can reach the point of having so many good cards in hand that PD will be more relevant to read opponents strategies, and when this time come maybe it will loose it's place in tier 1 decks, I hope.
Agree/disagree? What other cards cards you felt gained/loosed value after the cycle?
