Dune
Are Nexus cards public, and can a Karama cancel them?
The designer would rule that the Nexus discard pile isn't public, though with only 12 cards he doesn't think it matters much. A Karama doesn't affect Nexus cards. Players read the Atreides and Bene Gesserit Nexus effects as lasting for one fight, and the Emperor's for one card, not the whole turn.
