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

The next major chapter in the League of Legends Trading Card Game is coming with Riftbound: Radiance. Although Riot has not yet released all the details, the upcoming Riftbound Set 5 is already generating plenty of discussion in the TCG community. Radiance is particularly exciting for Collectors and Players because it is currently one of the most mysterious sets.

In this article, you will get a concise overview of all information known so far, the planned Release, possible contents, and why Radiance is worth checking out.

What is Riftbound: Radiance?

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

Officially, Riot has remained fairly tight-lipped so far. In the State of the Game from February 2026, Radiance was only briefly teased. There was some initial key art, but no specific information about cards or mechanics.

That is precisely what makes the set so interesting to many fans. While earlier sets were often presented in detail well in advance, 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:

• Preview Start: 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 make a special note of the preview phase. Traditionally, the first cards, mechanics, and highlights are revealed during this period.

However, it is also important to note that Riot itself points out that dates may still change. Delays are nothing unusual, especially with new TCG products.

What is known so far about the contents 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 treated with caution.

Planned card count

Several sources report that Riftbound Radiance cards will comprise approximately:

• are expected to comprise 180 cards
• could contain more than 60 Showcase cards

That would be a comparatively large set and particularly interesting for Collectors. Showcase cards are already considered a highlight in the Riftbound TCG, as they often stand out with special artwork and finishes.

Set theme

Various reports describe Radiance's overarching theme 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 yet.

Possible Champions in focus

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

• Ekko
• Seraphine
• Evelynn

This list has not yet been fully confirmed officially. Nevertheless, the selection fits well with the set's presumed theme. Seraphine and Ekko in particular represent creativity and innovation within the League of Legends world.

New product formats like Showdown Decks?

In addition to the classic boosters and Displays, Radiance could also provide greater support for new product formats. So-called Showdown Decks appear in several reports.

These could be preconstructed decks aimed particularly at:

• Beginners
• Casual Players
• Fast matches

direct.

However, the same applies here: Riot has not yet released a complete product overview. It remains to be seen whether and in what form these decks will actually be released.

Why Radiance is exciting for Players and Collectors

Even without a complete card preview, it is already clear why Riftbound new set Radiance is receiving so much attention.

For Players

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

Sets with creative themes in particular often bring:

• new strategies
• alternative playstyles
• Surprises in Deck building

For Collectors

Radiance is at least just as interesting for Collectors. The high number of Showcase cards and the focus on visual creativity could make the set particularly valuable.

If you enjoy pulling rare cards or enhancing the look of your Collection, you should definitely keep an eye on this set.

For Beginners

If you're new to the League of Legends TCG, Radiance could be a good starting point. New sets often bring a wave of attention, new products, and fresh ways to get started.

Especially if Showdown Decks actually appear, getting started will probably be even easier.

Which information is still missing

As exciting as the information so far may be, there are still several important points that have not yet been officially confirmed:

• Specific card lists
• New game mechanics
• Rarity distributions
• Exact product structure
• Complete Champion selection

This means that many details will only come to light when the Previews begin in September 2026.

But as a fan, this also has an advantage for you. The excitement remains, and every new announcement feels like a genuine Event.
