The card text says: The attacks of non-Ultra Beast Pokémon that have any basic Fighting Energy attached to them (both yours and your opponent's) do 10 more damage to the opponent's Active Pokémon (before applying Weakness and Resistance). If the attacking player has more Prize cards remaining than their opponent, those attacks do 40 more damage instead. The card text says: This card stays in play when you play it. Discard this card if another Stadium card comes into play. If another card with the same name is in play, you can't play this card.
The illustrator line reads 5ban Graphics. I count 1,629 other cards in the catalog with that illustrator.
Unbroken Bonds set binder is where a full Unbroken Bonds set goes. This card fills one slot there. Themed lists that include this exact card are Stadium cards. I still need this card.
