If he is a psyker he wins but if he's a standard marine he loses.
He isn't a psyker but he is far from a normal marine. He's one of the Primarchs (the Emperor's sons). He's a multi-hundred tonner, with huge reaction speeds (Sanguinus had lightspeed reactions and Lion sparred with him) and a blade that cuts down to a molecular level. To put it in perspective as a child he and his brothers destroyed moutains as they played.
