This puck was available as part of the Spiky-eared Pichu Set, sold in select 7-Eleven stores and Pokémon Centers from July 16, 2009, and from select theaters screening Arceus and the Jewel of Life from July 18, 2009 for a limited time.
Trivia
If this puck and Arceus are the only two pucks scanned in when beginning a game, the game will assign Giratina in its Origin Fomre as the third Pokémon.
