If Black Market {*} is in play, and an Active Darkness Pokemon with up to 3 Darkness energy and a Wishful Baton is Knocked Out by damage from an attack, can the player move all of the Darkness Energy from that Pokemon to another Pokemon and still get Black Market {*}'s effect?

Sorry, but no. Taking prizes is the last step when a Pokemon is knocked out; so after all the Darkness Energy is moved, the opponent would not take one fewer Prize card.
