Legend Box is a Trainer card. The listed subtypes are Item.
Legend Box sits at 75/90 in HS—Undaunted, position 75 of 91. Before it is 74 Flower Shop Lady, and after it is 76 Ruins of Alph. The set belongs to the HeartGold & SoulSilver series. It was released on August 18, 2010. The printed size is 90. This checklist is longer, at 91 cards. The listed rarity is Uncommon.
The card text says: Reveal the top 10 cards of your deck. If you reveal both halves of a Pokémon LEGEND, put those cards onto your Bench and attach all revealed Energy cards to that Pokémon LEGEND. Shuffle the other cards back into your deck. (You can play only 1 Pokémon LEGEND in this way.)
The illustrator line reads Shizurow. I count 79 other cards in the catalog with that illustrator.
HS—Undaunted set binder is where a full HS—Undaunted set goes. This card fills one slot there. I still need this card.
