I thought of an awesome combo with the Base Alakazam and a metal energy attached to a steel pokemon. Using Alakazam's damage swap pokemon power, swap damage from alakazam or any of your other benched pokemon and put them on the steel pokemon with metal energy attached to it. That way, the damage wouldn't be done to the pokemon with the metal energy attached to it, and you could completely heal all your pokemon at the same time during your turn. Make sure Alakazam is on your bench so he won't be in danger of being ko ed.
