Heal Energy is an Energy card. It is listed as Special.
Takumi Akabane illustrated this card. The same name is on 51 other cards in the catalog.
The card text says: Heal Energy provides Colorless Energy. When you attach this card from your hand to 1 of your Pokémon, remove 1 damage counter and all Special Conditions from that Pokémon. If Heal Energy is attached to Pokémon-ex, Heal Energy has no effect other than providing Energy.
I keep a set binder for POP Series 4, meant to hold every card of that set. This card is one slot in the POP Series 4 set binder. Themed lists that include this exact card are POP Series. I still need this card.
