Unown [N] (N2 #50)

Pokemon Power • [Normal]

Whenever a Colorless Pokémon damages 1 of your Pokémon, reduce that damage by 30 (after applying Weakness and Resistance). This power stops working if you have more than 1 Unown [N] in play. (This power works even if Unown [N] is Asleep, Confused, or Paralyzed.)
