The answer seems obvious, but I had a player this past weekend tell me that another judge says that you can not discard Double Colorless Energy with Crushing Hammer. After a search of Compendium BW Mobile and Ask the Rules Team I was unable to find any ruling in writing. I ruled you can discard Double Colorless Energy with Crushing Hammer. Figured I ask just to make sure I got the ruling correct and so that the ruling is accessible in the event someone else gets this same question.
If heads is flipped, can Crushing Hammer discard a Double Colorless Energy attached to an opponent's Pokemon?
