That still is a violation of entropy because you’ve increased the “order” of energy in the universe as a whole, which is not possible.
If you can violate entropy, one can create a more than perfect Carnot Engine (or in general just a heat engine with efficiency greater than 1) which would allow you to generate an infinite amount of energy in the form of mechanical motion.
Unless in creating/gaining “mana” one is accelerating the entropic decay of the universe as a whole equal to or greater than the amount of entropy reversed locally (eg spells must produce heat and be inefficient at converting mana energy into work), magic would violate thermodynamics and allow for infinite energy creation.
If I was shoe horning a magic system that co-exists with physics, I’d make magical black holes around the universe that are constantly sucking matter in and turning them into magic in some kind of sub space that eventually leaks back in as matter and regular energy. Close the system so to speak.
The magic probably takes the energy from somewhere else
Mana/chi/whatever
