Yes magick is real. As previously said, things like levitation, elemental control, flying and shape-shifting is not real. Things like astral projection, weather spells or working with spirits is real. This is a highly controversial topic, but no-one has proof of things like shape-shifting. Spells will not work if you do not have complete faith in your spell.
Magic has no physical properties, it only affects the way things happen around us. Things such as luck can be influenced because it is simple, magic is force that affects the way things happen, but only to an extent. This is my understanding of magic, I'm sorry if you disagree.
