Yes, Summer hologram succeeds as a fun themed collector set despite leaning heavily on reprints. The artwork and premium chase lineup do most of the heavy lifting, while the sheer number of returning cards and the game’s relatively young history keep it from pushing higher. What matters is that it rarely feels lazy. The summer presentation gives familiar material enough personality to make the whole release feel considerably fresher than the raw reprint count suggests.

Artwork






Summer hologram looks like it is having fun, and that matters. Bright colors, water, beaches, seasonal outfits, expressive poses, and playful compositions run throughout the set instead of appearing on a handful of showcase cards. In my opening, the artwork felt cheerful, refreshing, colorful, and genuinely fun. Even ordinary pulls had something worth stopping to look at. More importantly, the theme is consistent enough to give the entire release its own visual identity.
These do not feel like unrelated character illustrations thrown under a summer logo. They feel like pieces of the same event. The official product also gives new summer artwork to many returning cards, which is crucial when so much of the checklist is mechanically familiar. COVER’s card art direction feels increasingly confident here. The strongest cards are gorgeous, while the broader checklist maintains enough visual personality to make the set work as a collection rather than just a hunt for rarities.
Nostalgia Factor
This is not nostalgia in the usual decades old TCG sense, and pretending otherwise would be silly. The hololive OFFICIAL CARD GAME is still young. What Summer hologram does have is familiarity. Established talents return across the checklist, previously released cards come back in a dramatically different seasonal setting, and fans get recognizable characters presented with a lighter personality than the standard releases. That creates its own version of collector nostalgia.
Seeing a favorite holomem again matters, especially when the presentation has changed enough to make the card feel new in a binder. The 68 returning standard cards actually help this category more than they hurt it because the appeal comes from recognition rather than historical age. Still, there simply is not enough history behind the game yet for the set to deliver the deeper generational pull that the highest nostalgia scores should represent.



Set Depth
There is no getting around the big number: 68 of the 102 standard cards are reprints. Summer hologram is not pretending to be another completely new main booster, though, and its structure does a surprisingly good job of making that familiar foundation feel deliberate. Many returning cards receive new summer themed artwork, while Tokino Sora, Houshou Marine, and Hakui Koyori receive new Oshi holomem cards with new color options.
Then there is the parallel checklist, which is actually larger than the standard set at 112 cards. SEC, OUR, HR, UR, SY, SR, and S treatments give collectors plenty to explore beyond the basic checklist. That breadth saves the set. Mechanically familiar cards are still mechanically familiar, so the reprint count absolutely prevents this from feeling as substantial as a completely original booster. Visually and structurally, however, there is far more going on here than the word reprint initially suggests.

Opening Experience
Summer hologram was fun to crack because the colorful, lively artwork kept packs enjoyable even when the biggest rarities were not showing up. An SR or higher rarity card is guaranteed in every pack, giving each opening a visual payoff beyond the possibility of one enormous hit. This is where the artwork earns its keep. There was always something shiny to appreciate, even when it was not the card I was hoping for.
The summer theme also gave the opening a cohesive feel. Packs stayed within the same bright seasonal world, and that consistency was a big part of the charm. A guaranteed foil does not make every reveal equally exciting, though, and the smaller hits could not entirely replace the thrill of landing a premium rarity. Still, the steady flow of attractive cards made Summer hologram a lively, consistently enjoyable product to open.
Top Chase Appeal



The top end is where Summer hologram really flexes. The parallel lineup includes three SEC cards, three OUR cards, three HR cards, 15 UR cards, six SY cards, 76 SR cards, and six S cards, giving the release several layers of premium material rather than one lonely rarity sitting above everything else. The SEC cards are the clear centerpiece. Each features a replica hot stamped handwritten comment from the featured holomem, which gives them something more personal than rarity alone.
That fits this product beautifully because the entire theme is built around spending a summer with your oshi. OUR and HR cards add more serious collector targets beneath them, while UR and SY keep the upper portion of the checklist broad. The result is a chase structure with actual depth. You can have a favorite rarity, a favorite talent, or simply a favorite piece of artwork without the whole set collapsing into one card everyone is supposed to care about.
How we score
Each category is scored out of 10. Add the five category scores and divide by five for the overall FoilWire Score, shown to one decimal place. Each category contributes 20 percent. The score reflects our editorial judgment from a collector’s perspective. The category sections explain the evidence and limitations.
- 9.2–10.0: Legendary — A standout release with broad collector appeal, strong identity, and exceptional overall execution. A 10.0 is reserved for a set with no meaningful weakness across all five categories; being iconic, historic, expensive, or popular by itself is not enough.
- 8.4–9.1: Memorable — A very strong set with real strengths, even if one or two areas keep it from top-tier status.
- 7.5–8.3: Noteworthy — A worthwhile release with clear positives, though it may be more niche or uneven overall.
- 6.3–7.4: Mixed — A set with some interesting elements, but noticeable weaknesses in depth, excitement, or long-term identity.
- 0–6.2: Forgettable — A release that struggles to stand out and offers limited lasting appeal outside a narrow audience.
