Entei WBSP 34

Whenever your opponent's attack damages Entei, unless that attack Knocks Out Entei, flip a coin. If heads, shuffle Entei and all cards attached to it into your deck. This power can't be used if Entei is already Asleep, Confused, or Paralyzed when it is damaged.

During your opponent's next turn, prevent all effects of attacks, including damage, done to your Benched Pokémon.
