Well I can tell you from experience that magic is very real however the shape shifting that you would like to see that will prove to you that magic is real does not exist in this time and place. So you might want to take this as a card that means magic is not real and move on or you can take this as a card that means you need to learn more about the art of magic. It is up to you.
I can tell you that through astral projection one can learn to shape shift on the astral plane.
If you would like to know more and experience magic first hand the first thing you need to do is learn how to meditate. I don't just mean for a week but for months, at least a year. As you practice meditation also take time to read all that you can about the different forms of magic. Astral projection, chakras, shielding, how to cast, divination, astrology, the elements, herbalism, crystals and stones, oils and incenses, magic symbols, and different religions that utilize magic.
