Once during your turn (before your attack), you may flip a coin. If heads, choose a Stadium card from your discard pile and put it into play. (If there's already a Stadium card in play, discard it.) This power can't be used if Dark Porygon2 is Asleep, Confused, or Paralyzed.
Flip a coin. If heads, prevent all damage done by attacks to Dark Porygon2 during your opponent's next turn. (Any other effects of attacks still happen.)
