Put 2 Energy attached to your Pokémon in the Lost Zone.
VSTAR Power
Star Requiem スターレクイエム
You can use this attack only if you have 10 or more cards in the Lost Zone. Your opponent's Active Pokémon is Knocked Out. (You can't use more than 1 VSTAR Power in a game.)
This card was included as a Regular card, a Rainbow Rare, and as a Secret card in the Lost Origin expansion, first released in the Japanese Lost Abyss expansion, each with artwork by 5ban Graphics. The Regular print was reprinted, alongside a new Secret print with artwork by AKIRA EGAWA, in the Japanese VSTAR Universe subset. This Secret print was later released outside Asia as part of the Crown Zenith expansion's Galarian Gallery.
This is the only Pokémon VSTAR depicting a member of the creation trio that classifies it as as its secondary Dragon-type rather than its primary type.
