Strength Charm
Whenever an attack from the Pokemon that Strength Charm is attached to does damage to the Active Pokemon (after applying Weakness and Resistance), the attack does 10 more damage. At the end of the turn in which this happens, discard Strength Charm.
Card rule
Attach Strength Charm to 1 of your Pokémon that doesn't already have a Pokémon Tool attached to it. If that Pokémon is Knocked Out, discard this card.
