Once during your turn, when you play Meganium from your hand to evolve 1 of your Pokémon, you may search your deck for up to 3 in any combination of Basic Pokémon or Evolution cards. Show them to your opponent and put them into your hand. Shuffle your deck afterward.
During your opponent's next turn, any damage done by attacks from the Defending Pokémon is reduced by 30 (before applying Weakness and Resistance).
