Once during your turn, when you put Azelf from your hand onto your Bench, you may look at all of your face-down Prize cards. If you do, you may choose 1 Pokémon you find there, show it to your opponent, and put it into your hand. Then, choose 1 card in your hand and put it as a Prize card face down.
The Defending Pokémon can't retreat during your opponent's next turn.
