Once during your turn (before your attack), when you attach a Energy card from your hand to Raikou, you may put one damage counter on one of your opponent's Benched Pokémon.
Discard 3 cards from the top of your deck. This attack does 50 damage plus 10 more damage for each Energy card you discarded. Then, attach those Energy cards to 1 of your Pokémon.
This card was included in the Secret Wonders expansion, first released in the Japanese Shining Darkness expansion. In September 2010, an exclusive Cracked Ice Holofoil print of this card was released in the Fall 2010 Collector's Tins in order to showcase the difference between normal and Shiny Pokémon.
