Being ousted by Secrets & Top Secrets does give a final retaliation. Propaganda does not.
Official site suggests creating a sideboard of Secrets. Put the number of secrets in the deck that you think is appropriate, then whenever one is drawn, instead of being used, it is put on the bottom of the sideboard deck and the top card of that deck is drawn instead.
It allows all secrets to be used occasionally without having to go through the deck & change them out between games.
