Team Rocket's Hypnotizer
If the Team Rocket's Pokemon this card is attached to is in the Active Spot and is damaged by an attack from your opponent's Pokemon (even if this Team Rocket's Pokemon is Knocked Out), the Attacking Pokemon is now Asleep.
Card rule
You may attach any number of Pokémon Tools to your Pokémon during your turn. You may attach only 1 Pokémon Tool to each Pokémon, and it stays attached.
