With that point I still don't think Yhwach's a Quincy, regardless of the fact he Medallized Zanka no Tachi. This is because I don't think the Medallion technique is Quincy-related at all (barring the fact that it is only used by Quincies) but is merely a technique developed to massively hinder the Shinigami. My reasoning for this is that the Quincies can't use Vollständig while they possess a bankai; it's fragile reasoning, but it's an reasoning nonetheless.
