Poké-BodyReactive Shield

As long as Tentacruel has any React Energy cards attached to it, prevent all effects, including damage, done to any of your Tentacruel in play by attacks from your opponent's Pokémon-ex.

Choose 1 of your opponent's Pokémon. This attack does 20 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
