I work with dragon magyc frequently, I find you can draw it in easier if you're a cardinal (fire) zodiac sign (I'm an Aries).
I was actually given a tulpae form of my guardian dragon. A being that's watched me life to life, I was blessed to know of her presence this incarnation

she's how I actually got into dragon magyc.
Dragon magyc is VERY powerful. It's basis is manifestation in the form of a complete change/transmutation, so if you want to incorporate it into your energy pattern, be careful to choose wisely what you decide to change, it will change COMPLETELY and fully, so it must be a part of your life you're completely ready to change and shed.
