Sylveon ex

During your opponent's next turn, attacks used by the Defending Pokémon do 100 less damage (before applying Weakness and Resistance).

Choose 2 of your opponent's Benched Pokémon. Shuffle those Pokémon and all attached cards into your opponent's deck. If 1 of your Pokémon used Angelite during your last turn, this attack can't be used.

Pokémon ex rule: When your Pokémon ex is Knocked Out, your opponent takes 2 Prize cards. Tera: As long as this Pokémon is on your Bench, prevent all damage done to this Pokémon by attacks (both yours and your opponent's).
