PokÃ©mon Power Hard Shell
Whenever an attack (including your own) does 40 or less damage to Shuckle (after applying Weakness and Resistance), reduce that damage to 10. (Any other effects of attacks still happen.) This power stops working while Shuckle is Asleep, Confused, or Paralyzed.
Flip a coin. If heads, the Defending PokÃ©mon is now Poisoned. It now takes 20 Poison damage after each player's turn (even if it was already Poisoned).
