With your first two statements. Gray gained SILVER's magic AKA Ice Devil Slayer Magic, Gray is an Ice-Make mage, he just implemented Ice Make with Ice DeS magic, not hard to understand. And that Secret Art Natsu used he had used it on Zero too during the Orácion Seis Arc, he just looked different. Yeah seeing they training would be really good.
