If your opponent has only 1 Prize card left and Regice is the only Pokémon you have in play, this attack does 30 damage to each of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
Trivia
Origin
Like with all Pokémon ☆ cards, this card is intended to represent the Shiny version of a Pokémon. However, in this particular instance, that trait does not seem to follow up entirely. While Shiny Regice are a light blue color, the one represented on the card is a green color.
