• This card's name could be a reference to Mercury's orbit in various ways, such as being the smallest one among all the planets in our Solar System (hence it orbits around the Sun the fastest), or that it exhibits the highest precession (that is, the entire shape of the orbit itself also drifts around the Sun, due to relativistic effects of the star's gravity).
    • Its WATER Attribute is a reference to the Japanese name of the planet being 「水星」, which literally means "Water Star".
