As long as this Pokémon is your Active Pokémon, whenever you attach an Energy from your hand to it, it is now Asleep.
[C][C][C] Hypno Roll: 100
This attack can be used if this Pokémon is Asleep. If it is not Asleep, this attack does nothing.
It is born asleep, and it dies asleep. All its movements are apparently no more than the results of it tossing and turning in its dreams.
