Pokémon Power Fluffy Wool
During your opponent's turn, if Light Piloswine is your Active Pokémon and is damaged by your opponent's attack (even if it's Knocked Out), flip a coin. If heads, the attacking Pokémon is now Asleep. This power stops working if Light Piloswine is already Asleep, Confused, or Paralyzed when your opponent attacks.
If there is a Stadium card in play, you may discard it.
