it could in theory work actually. but if you're unexperienced, or don't have a working knowledge of dragons, or wish to summon for the wrong reason it will fail.
that being said DO NOT SUMMON A DRAGON. i would advise against not summoning any creature if you do not know what you're doing but dragons especially. they have been missused by humans in the past, so they are cautious around us and if you summon the wrong dragon, they WILL attack you. for instance, fire dragons are rather hostile to humans, and choas dragons do not like being bothered. earth dragons are shy and it takes a while to befriend them, so they might attack if you have them confined in your circle.
