X-Rays

X-rays make up X-radiation, a form of
high-energy electromagnetic radiation.
Most X-rays have a wavelength ranging from 0.03
to 3 nanometres, corresponding to frequencies in
the range 30 petahertz to 30 exahertz and energies
in the range 100 eV to 200 keV.
Special Ability for X-Rays: If a player plays all
four X-Ray cards at once, they may choose one
player and view their hand.
