At first, I thought a 3P solution might be impossible, so I went ahead and built a Rate solution first. After finishing it, I decided to experiment with a 3P layout just to see if it was viable—and to my surprise, it actually worked! It even took me less time to build than the Rate solution. I'm so glad I didn't waste any time trying to make a 4P solution.
I've been sinking all my time into Pokemon Pokopia over the past few weeks, which is why I ended up rushing this OM puzzle right at the deadline. Also, thank goodness the current puzzle doesn't require the Glyph of Duplication, because I still haven't finished Chapter 2 of De Re Metallica yet!
