Riftbound: Radiance – Everything known so far about the upcoming 5th set

With Riftbound: Radiance, the next big chapter in the League of Legends Trading Card Game is coming. Even though Riot has not yet released all details, the upcoming Riftbound Set 5 is already generating a lot of buzz in the TCG community. Radiance is especially exciting for collectors and players because it currently ranks among the most mysterious sets.

In this article, you will get a compact overview of all known information so far, the planned release, possible content, and why taking a look at Radiance is worthwhile for you.

What is Riftbound: Radiance?

Riftbound Radiance is currently the fifth set of the League of Legends TCG and is intended to complete the release schedule for Riftbound 2026. The name was first mentioned during a recap of PAX Unplugged and later confirmed in the official roadmap.

Officially, Riot is still keeping things quite under wraps. In the State of the Game from February 2026, Radiance was only briefly teased. There was a first key art, but no concrete information about cards or mechanics.

This is exactly what makes the set so interesting for many fans. While earlier sets were often detailed early on, Radiance has so far deliberately remained in the shadows.

Riftbound Radiance Release Date and Schedule

One area that is already clearer concerns the schedule. According to the official roadmap, you can expect the following dates:

• Start of Previews: September 21, 2026
• Pre-Rift Phase: October 16 to 22, 2026
• Official Release: October 23, 2026

If you actively play or collect Riftbound, you should especially note the preview phase. During this time, the first cards, mechanics, and highlights are traditionally presented.

But it is also important: Riot itself points out that dates can still change. Especially with new TCG products, delays are not unusual.

What is known so far about content and scope

Even though many details are still missing, there is already some information from reports and preview materials. These mostly come from TCG media and should therefore be taken with caution.

Planned card count

Several sources report that Riftbound Radiance cards will total about:

• expected to comprise 180 cards
• which could include over 60 Showcase cards

This would be a comparatively large set and particularly interesting for collectors. Showcase cards are already considered a highlight in the Riftbound TCG because they often stand out due to special artworks and finishes.

Theme of the set

In various reports, the overarching theme of Radiance is described as Creativity and brilliance in Runeterra. This suggests that the set could take new visual and stylistic paths.

Especially if you value artwork, lore, and unique cards, Radiance could become one of the most exciting sets so far.

Possible champions in focus

Another exciting point is the currently mentioned champions. According to previous reports, the following figures could play a central role:

• Ekko
• Seraphine
• Evelynn

This list is not yet officially confirmed in full. Nevertheless, the selection fits well with the suspected theme of the set. Especially Seraphine and Ekko stand for creativity and innovation within the League of Legends world.

New product formats like Showdown Decks?

Besides the classic Boosters and Displays, Radiance could also support new product formats more strongly. Several reports mention so-called Showdown Decks.

These could be pre-built decks, especially aimed at:

• Beginners
• Casual players
• Fast matches

arranged.

However, the same applies here: A complete product overview from Riot is still pending. Whether and in what form these decks will actually be released remains to be seen.

Why Radiance is exciting for players and collectors

Even without a full card preview, it is already clear why Riftbound's new set Radiance is getting so much attention.

For Players

If you actively play Riftbound, Radiance could bring fresh wind into the meta. New champions and possible mechanics almost always lead to changes in gameplay.

Sets with creative themes often bring:

• new strategies
• alternative playstyles
• Surprises in Deck building

For Collectors

For collectors, Radiance is at least just as interesting. The high number of Showcase cards and the focus on visual creativity could make the set especially valuable.

If you like to pull rare cards or visually enhance your collection, you should definitely keep this set in mind.

For Beginners

If you are new to the League of Legends TCG, Radiance could be a good entry point. New sets often bring a wave of attention, new products, and fresh entry opportunities.

Especially if Showdown decks actually appear, the entry will probably become even easier.

Which information is still missing

As exciting as the current information is, there are still some important points that have not yet been officially confirmed:

• Concrete card lists
• New game mechanics
• Rarity distributions
• Exact product structure
• Complete champion selection

This means: Many details will only come to light with the start of previews in September 2026.

For you as a fan, this also has an advantage. The excitement remains, and every new announcement feels like a real event.

A final highlight for 2026

Riftbound Radiance is already one of the most exciting upcoming TCG Releases. Even though many details are still missing, the current status clearly shows that Riot is preparing a special set here.

With a planned Release in October 2026, a strong thematic focus, and potential highlights like Showcase cards and new deck formats, Radiance has the potential to become one of the most important sets in the Riftbound TCG.

If you love trading cards, enjoy trying out new strategies, or simply appreciate strong artworks, you should definitely keep an eye on this set.

As new information, cards, or official previews appear, the picture will become clearer. Until then, Radiance remains exactly what makes a good TCG set: a promise of something great.
