Thanks, you did it! I started with that pattern but failed to find anything I liked, so I ended up bloating it into the horrible MUG. I thought I considered that set of guardians too but maybe I didn't. Or perhaps I just didn't see a short solution with them, can't remember.
Unfortunately your solution seems to have a similar problem to mine. As far as I see, it's also degenerate because it contains a simpler strong link (2r1c5 is used both on and off). Perhaps there simply isn't any uniqueness solution here that would actually make sense, but who cares. They're still fun!
