As long as this Pokémon is your Active Pokémon, any damage done to your Pokémon by an opponent's attack is reduced by 30 (after applying Weakness and Resistance).

このポケモンがバトル場にいるかぎり、自分のポケモン全員が、相手のポケモンから受けるワザのダメージは「-30」される。

If you played a Supporter card from your hand during this turn, this attack does 70 more damage.

この番、手札からサポートを出して使っていたなら、70ダメージ追加。
