You can both put in Saber and I'll check to see which one is more suitable for the role. I'll reserve for you both.
And it's fine if you don't know about magic circuits, let me explain what they are. 

Magic Circuits are a pseudo-nervous system that spreads itself through the human body and what qualifies a person to be a magus. Their normal functions are to act as paths that convert Life Force into magical energy, but humans learned how to control it and use it to perform mysteries. They are that which connects the material world to the astral plane, the paths which connect to the foundations underlying Grand Rituals. For example, one person in the show Rin Tohsaka, has 40 inborn magical circuits. She has the potential to output 1000 units of magical energy.
