Create a new rule called “Marks” as follows:

Each Reader may have zero or more Marks; this is tracked in the GNDT. By default, a Reader has no Marks. A Mark is the name of a specific Card. If a Reader has a Mark of a given Card, that Reader may act as if that Card is active at any time.

A Mark does not change that Card’s Revealed or Unrevealed status. Ongoing effects from a Mark apply only to the Reader with that Mark, unless that Card is active in the Spread. A Reader with the Mark of a given Card may not use a Mark to act as if that Card had just been drawn or discarded.
