Carol Marcus (2022-06-24) - Lore updated ("David Marcus").
Containment Field (2022-08-01) - May not leave play. No longer a hidden agenda. No longer has Going To The Top restriction. Cannot be used anymore to one-sidedly tax opponent's downloads by discarding with Q the Referee and retrieving with Tribunal of Q.
Defend Homeworld (2022-08-01) - Nerf. Removed [Referee] icon. Added "voluntarily" to prevent combo with Chula: The Way Home & The Issue Is Patriotism.

Dr. McCoy (2020-06-01) - Dr. McCoy's ability to repeatedly nullify MEDICAL dilemmas was overwhelming to several dilemma strategies and overly powerful. His errata limits this ability to once per game.

The Wake of the Borg (2020-02-03) - Nerf. Targets the Neutral Zone only if heavily used. Returns to hand instead of destroys. Borg are immune. Nullifiable. No longer a Ref card.
