This fighting style is so old they can use it with ease and instinctively

Pendamancy: This is an art practiced by Marz after he released his Reconstruction ability from his body, this type of magic is the ‘Awakened’ state of Reconstruction leaving his body. It was lost due to an operation Terra performed on him, using her “Control” ability. This power is a form of exchange magic that involves a large amount of upper body movements, but when mastered he can replace his arm movements with hand and figure movements. The magic also works like a pendulum, if an element is moved or changed, he can reverse it or in some cases completely shift the force in another direction. There are not any known weaknesses to this magic, expect the use of other forms of exchange magic. The result of “Awakening” this ability is being able to subtract a trait from a certain object it and move it to another, and as a pendulum it weakens over time. This power can affect anything that can or has an equal opposite. E.g., if a bullet/s were fired at him, he could reverse either the time placement forcing it back into the gun or he could change the forward force into a backwards force, sending the bullet back to where it came from.
