Cowardice is listed as Pokémon Power. At any time during your turn (before your attack), you may return Tentacool to your hand. (Discard all cards attached to Tentacool.)

Legendary Collection set binder is where a full Legendary Collection set goes. This card fills one slot there. A generation binder holds one card of each species. Tentacool can fill a slot in Generation 1 binder (Kanto). I still need this card.
