When Pokémon-ex has been Knocked Out, your opponent takes 2 Prize cards.
As long as Ampharos ex is in play, whenever your opponent attaches an Energy card to his or her Pokémon from hand, put 1 damage counter on that Pokémon. You can't put more than 1 damage counter even if there is more than 1 Ampharos ex in play.
Flip a coin. If heads, this attack does 40 damage plus 30 more damage. If tails, the Defending Pokémon is now Paralyzed.
