“Toss a coin and call Heads or Tails. If you call it right, your opponent's monsters on the field are destroyed. If you call it wrong, your own monsters on the field are destroyed and you lose Life Points equal to half the total ATK of the destroyed monsters. This card can be used only during your own turn, once per turn.”
