Well, this just feels like an "I just solved it" kind of solution, but it's the best I got for Griix Zropz > Vuip * Myssis > Xiro, so you get what you get.  It doesn't feel very good.

It took me longer than I want to admit to figure out what Griix Zropz was, because my original solves ended up accidentally scoring 0 every time.

I think I did okay for starting to solve this puzzle with 7 hours until the deadline.
