hololive OFFICIAL CARD GAME English
This is a release for the hololive OFFICIAL CARD GAME itself, a standalone trading card game, and should not be confused with hololive products released for Weiss Schwarz. The official card database already lists Summer hologram cards under the Extra Booster set.
Reprints Get a Summer Makeover
Of the 102 standard card types, 68 are selected reprints from products released through Booster Pack: Enchant Regalia in April 2026. Returning cards also receive new summer themed artwork. Tokino Sora, Houshou Marine, and Hakui Koyori receive Oshi holomem cards in new colors, opening additional deck building options. The mix of new cards and reprints is also designed so players can build decks using cards from the Extra Booster itself.
Built for Two Audiences
Summer hologram appears designed to bridge players looking for useful returning cards with collectors interested in new artwork and premium treatments. That makes the first Extra Booster an approachable introduction to a side of hololive OCG that puts its characters and presentation front and center.
