Although automata can use magic as naturally as breathing, that does not mean that they can use all magic in the world.
As I said before, the function of the magic circuit in this world is no different from the magic circle. It is just a device that condenses all the processes of performing magic into the body of the doll.
In this case, there is bound to be a problem to face.
Just like different magic circles are required to perform different magics, the magic circuit built into the automaton can only produce one magic effect.
In other words, there is only one magic that the automaton can freely use.
Two completely different types of magic cannot exist in one individual at the same time. This is the basis of trick physics (the Principle of Incoordination of Magical Activity).
There will never be two magic effects present in one individual at the same time.
Otherwise, they will interfere and repel each other, thus preventing the effects of magic from being exerted. This is a theory of magic that the world has not yet conquered.
But there is one exception to this principle.
The exception is the magic circuit
