Knight of Swords

The knight of Swords shows an person cladded in armor with a yellow covering, which has lizards on it.  The knight is looking, assessing the situation and looking for an opening to attack or to stand down.  The horse is ready to move at his command, and is a symbol for movement or moving forward, quickly.  The lizards are also a symbol for quickness but also for transformation.  The feathers on the armor remind me of fire.  The ground below the rider is level and I would read this as being level-headed or in command of emotions.

When this card appears in a reading the question needs to be asked, "is this situation worth going after?"  "Will there be more harm than good?"  "What are the ramifications and who will benefit or suffer?"
