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

With Riftbound: Radiance, the next major chapter in the League of Legends Trading Card Game is on the way. 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.

This article gives you a concise overview of everything known so far, the planned Release, potential 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 wrap up the Riftbound 2026 release schedule. The name was first mentioned in a recap of PAX Unplugged and later confirmed in the official roadmap.

Riot has so far kept things pretty quiet officially. In the February 2026 State of the Game, Radiance was only briefly teased. There was some initial key art, but no concrete information about cards or mechanics.

That is exactly what makes the set so interesting to many fans. While earlier sets were often revealed in detail early on, Radiance has so far deliberately remained in the shadows.

Riftbound Radiance Release date and schedule

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

• Previews begin: 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 note of the preview phase in particular. Traditionally, this is when the first cards, mechanics, and highlights are revealed.

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

Although many details are still missing, some information is already available from reports and preview materials. Most of these come from TCG media and should therefore be treated with caution.

Planned card count

Several sources report that Riftbound Radiance cards will total around:

• to contain 180 cards
• including over 60 Showcase cards

That would make it a comparatively large set and especially interesting for Collectors. Showcase cards are already considered a highlight of 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 directions.

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 being mentioned. According to reports so far, 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 in the world of League of Legends.

New product formats like Showdown Decks?

Alongside the classic boosters and Displays, Radiance could also offer greater support for new product formats. Several reports mention so-called Showdown Decks.

These could be preconstructed decks aimed especially at:

• Beginners
• Casual Players
• Quick matches

align.

However, the same applies here: Riot has yet to provide 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's already clear why Riftbound's new Radiance set is getting so much attention.

For Players

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

Sets with creative themes often bring:

• new strategies
• alternative play styles
• 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 enjoy pulling rare cards or visually enhancing 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 great starting point. New sets often bring a wave of attention, new products, and fresh opportunities to get started.

Especially if Showdown decks do become available, getting started will likely be even easier.

Which information is still missing

As exciting as the information so far may be, there are still a few important points that haven't been officially confirmed yet:

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

That means many details won't come to light until previews begin in September 2026.

But as a fan, there's an upside for you too. The excitement stays alive, 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. Although many details are still missing, the current information clearly shows that Riot is preparing a special set.

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 great artwork, you should definitely keep an eye on this set.

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