Wobbuffet

Pokemon

To keep its pitch-black tail hidden, it lives quietly in the darkness. It is never first to attack. [Psychic] Counter: If an attack damages Wobbuffet during your opponent's next turn (even if Wobbuffet is knocked out), flip a coin. If heads, Wobbuffet attacks the Defending Pokémon for an equal amount of damage.
