You can't have more than 1 ◇ card with the same name in your deck. If a ◇ card would go to the discard pile, put it in the Lost Zone instead.

Once during each player's turn, that player may heal 60 damage and remove all Special Conditions from 1 of their Pokémon. Whenever any player plays an Item or Supporter card from their hand, prevent all effects of that card done to this Stadium card.
