Yoda
I don't know that Vrook's lightsaber techniques are meant to be dazzling, but I know that really his only formidable ally is his knowledge of the Force
Yoda is both a master of Form I lightsaber combat (thought lost along with Tulak Hord and his Sith Holocron) and the Force itself. Bearing in mind of course that other than Anakin, Yoda had the highest midichlrion count of any Jedi and therefore a far greater capacity in the Force
