Bit of confusion today over Skype league match today with another pokebeach member.
Opponent had Gengar SF as active with 1 {P} and 1 Rescue Energy attached.
Knocked it out with Beat Up from Sneasel.
He discarded both energies and took all Gengar, Haunter and Gastly back into his hand.
Is that the right way to play it? Or should he have discarded everything including basic and stage 1 since they were cards ATTACHED to the pokemon as is/per the rescue energy too?
