Princess Twilight is my Princess of Air (corresponds to the King of Swords in a normal deck). Like Luna, it is Twilight’s struggle with her element that makes her a good fit for this role in this deck: reversed, she is absolutely intellect out of control and applied in ways it was never intended to be used. Upright, she is the tension of wise leadership; the desire to fix things ourselves tempered by the desire to do right and to delegate affairs with wisdom.
 
So, like so many things in FiM, she’s here because of what she most needs to learn herself. This card is her own personal “hero’s journey”.
