>>95880273 (OP)If I'm forced to choose, I'd probably go with the nine spheres. They are but a conceptual crutch for young mages to work with. A mage's growth comes from realizing and internalizing that this separation of concepts is arbitrary and that reality, as well as true magic, are just one shapeless whole.
Schools work well enough but ultimately it's just categorizing what your spells do.
As much as I like the winds of magic, they suffer from a common Warhammer issue of the lore starting off from introducing cool shit first, then attempting to retrofit it into a coherent lore, with mixed results. How is death opposed to metal instead of life, life opposewd to fire, or beasts opposed to astrology? How come fire gets to ahve an entire winds for itself, but other classical or eastern elements don't?
Not too familiar with M:tG to be honest,
