Pot Helmet

Pot Helmet
If the Pokémon this card is attached to doesn't have a Rule Box, it takes 30 less damage from attacks from your opponent's Pokémon (after applying Weakness and Resistance). (Pokémon V, Pokémon-GX, etc. have Rule Boxes.)
Attach a Pokémon Tool to 1 of your Pokémon that doesn't already have a Pokémon Tool attached.
