Anyone may use a Trump – the user does not need to be an Amberite, a Pattern initiate, or of royal blood. Similarly, no special characteristics are required in the person depicted on a Trump – for example, in "Blood of Amber", several initiates of the Logrus were depicted on Trump cards drawn by Brand or Rinaldo, and Merlin considered drawing a Trump depicting Bill Roth, a trusted advisor with no apparent magical aptitude. Provided the artist is sufficiently familiar with the subject, a Trump can be drawn for any person or place desired, unless the place is in constant motion and change (such as portions of Chaos). Under certain circumstances and extreme conditions, the technique for creating a Trump can be used to make contact without drawing on any surface at all. Indeed, Corwin's brother Brand is described as becoming a "Living Trump", who can move through Shadow by will alone.
