Damage done to any of your Raichu ex in play by attacks from your opponent's Pokémon-ex is reduced by 30 (after applying Weakness and Resistance). You can't use more than 1 Rai-shield Poké-Body each turn.

Power Short

Choose 1 of your opponent's Pokémon. This attack does 30 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) If that Pokémon has Poké-Powers, this attack does 30 damage plus 20 more damage.
