I think today‘s list harmonizes very, very well.
I didn‘t immediatly get how good it works until I tried to adapt the idea of Soontir+Vizier. My idea was to make a Whisper Soontir Vizier list. But this adds several problems and does not harmonize at all, because Whisper is not as big of a threat as Vader. And the free points scream for increased defense on Soontir, including LoneWolf, but that is of course nonsense when the whole point is to keep Vizier within range 2.
Reviewing your list after playing around like this had me realize that it‘s a nicely crafted puzzle.
