Pokémon Power Time Travel
If an opponent's attack would Knock Out Celebi, flip a coin. If heads, Celebi isn't Knocked Out and you shuffle it and all cards attached to it into your deck. This power doesn't work if Celebi is already Asleep, Confused, or Paralyzed.
Flip 3 coins. For each heads, put 1 damage counter on the Defending Pokémon.
