During your control phase, fire Superlaser as follows:
Name the System: Use X Force to target a planet system Death Star is orbiting.
You May Fire When Ready: Draw Destiny.
Stand By: If (destiny +Y -Z) > 8, target system is "blown away" and this card is lost. Otherwise, this card is used and one Death Star Gunner on table is lost (your choice).
X = total sites at target.
Y = total Death Star sites where opponent has no presence.
Z = opponent's choice of X or total sites at one Rebel Base (Yavin 4 or Hoth).
