A new Extra Booster, Summer hologram, joins the hololive OFFICIAL CARD GAME!
Unlike a standard Booster Pack, the Extra Booster is a special booster product line, with each release built around a unique theme.
The theme of this Extra Booster is: “That Summer Spent with Your Oshi.”
More than half of the cards in this set are carefully selected reprints from previously released cards, so that card you’ve been hoping for might finally make a comeback!
Of course, the set also includes brand-new cards! Oshi holomem cards with new colors for Tokino Sora, Houshou Marine, and Hakui Koyori let you build and enjoy brand-new decks.
Not only do the new cards feature summer-themed artwork, but the reprinted cards do as well. Whether you’ve just started playing holoca or have been with us from the beginning, this is a product you won’t want to miss!
