Compelling thought. One slight flaw is that the Windrunner will have both Plate and Blade, both of which will make it significantly more difficult for the fullborn to win. Although, if neither one knew the other’s powers and were just told to kill one another, I find it difficult to believe that the Windrunner would try to kill the fullborn without prompting, due to the First Ideal. But if the Windrunner were to attack quickly, I think they may be able to catch the fullborn off guard. Ultimately, I feel like the Windrunner could win, but it would be close.
