Whenever you attach a Water Energy card from your hand to Vaporeon, remove all Special Conditions affecting Vaporeon.
If the Defending Pokémon has any Energy cards attached to it, flip a coin. If heads, choose 1 of those Energy cards and move it to 1 of your opponent's Benched Pokémon. If your opponent has no Benched Pokémon, ignore this effect.
The Defending Pokémon is now Asleep.
