Finding a magic system that does what I want is difficult. Not in the least because what I want from a magic system differs constantly depending on the sort of game I am (considering) playing.
However, one consistent ask that I have of magic is that it makes sense in the world, at least to me. So very gamey takes on magic, though they might be fun to play with, don't do it for me personally.
Other than 'making sense in the world' I wanted the magic for this game to feel like a genuine force of nature, rather than vague innate power. I think it worked pretty well, but we'll see when I test it at the open table game I run for my students if it actually works in practice.
