Entei
How it was given out: Premium File 2.
Japanese promo, released 2000.
One of 278 promos from 1999 to 2003 listed on this site.
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.
