Venomoth

It flutters its wings to scatter dustlike scales. The scales leach toxins if they contact skin.

Poke-BODY — Dangerous Scales: If Venomoth is your Active Pokémon and is damaged by an opponent's attack (even if Venomoth is Knocked Out), the Attacking Pokémon is now Asleep and Poisoned.

Disturbance Dive (50): Prevent all effects of an attack, excluding damage, done to Venomoth during your opponent's next turn.
