With a Lunar Magic capable of affecting the real world, there would be so many possibilities of what someone could do with such power.
I'd probably use it to set up elaborate Rube Goldberg levels, ride a Yoshi around, edit the palettes of personal items, make myself a Torpedo Ted friend, or maybe even fix things! With Lunar Magic, dilapidated buildings could be completely rebuilt, and new buildings would be built fairly fast. I likely wouldn't be the one doing things like that though, since I barely know anything about architecture. But again, there are so many possibilities that can come out of a concept like this. Deleting plastic from the ocean, copying resources to disperse around the world, using the undo button to rid of mistakes, making another entire planet for new generations of humans and animals to live in! The list goes on for who knows how long.
I can also totally see people making Kaizo levels irl.
