Mesprit (LA #34)

Poke Power • Psychic Bind

Once during your turn, when you put Mesprit from your hand onto your Bench, you may use this power. Your opponent can't use any Poké-Powers on his or her Pokémon during your opponent's next turn.

If you have the same number of cards in your hand as your opponent, this attack does 20 damage plus 50 more damage.
