Every Riftbound Radiance HEARTSTEEL Card: Complete 6-Card List

Riftbound: Radiance has six HEARTSTEEL cards, bringing K'Sante, Aphelios, Ezreal, Yone, Kayn, and Sett together in one premium Overnumbered lineup.

The six cards are numbered consecutively from RAD 178/167 through 183/167, with HEARTSTEEL artwork by Luscinia Studio.

Five are new HEARTSTEEL printings of cards previously released in Origins or Spiritforged. K'Sante, Courageous is the exception. Its standard printing is also part of Radiance.

Every Riftbound Radiance HEARTSTEEL Card

The complete Radiance HEARTSTEEL checklist is:

All six are Overnumbered Champion Units. Radiance's standard collector numbering ends at 167/167, placing the HEARTSTEEL cards beyond the normal set sequence as premium collectible treatments.

K'Sante, Courageous

K'Sante, Courageous #178/167 starts the HEARTSTEEL lineup.

K'Sante is the unusual member of the group because the standard version of K'Sante, Courageous is also a Radiance card, numbered 086/167. The other five HEARTSTEEL cards are alternate printings of cards from earlier Riftbound sets.

K'Sante, Courageous is a Body Champion Unit with 4 Might that costs 5 Energy. It has Accelerate and Shield 2, plus an ability that channels a rune when K'Sante holds a battlefield.

Aphelios, Exalted

Aphelios, Exalted #179/167 is the second Radiance HEARTSTEEL card.

The original Aphelios, Exalted appeared in Spiritforged as #049/221. Radiance brings the same card back with new HEARTSTEEL artwork as an Overnumbered printing.

Ezreal, Dashing

Ezreal, Dashing #180/167 is the third card in the HEARTSTEEL checklist.

The original Ezreal, Dashing appeared in Spiritforged as #082/221. The Radiance version gives the existing card a new HEARTSTEEL printing illustrated by Luscinia Studio.

Don't confuse it with Ezreal, Prodigy. Riftbound has multiple Ezreal cards, but Ezreal, Dashing is the one included in Radiance's HEARTSTEEL lineup.

Yone, Blademaster

Yone, Blademaster #181/167 continues the six-card lineup.

The original Yone, Blademaster appeared in Spiritforged as #116/221. The Radiance HEARTSTEEL printing uses Riot's revised wording for the card.

The original text referred to conquering an "open battlefield." Riot later issued official errata changing the ability to trigger when Yone conquers a battlefield that was uncontrolled. The HEARTSTEEL printing reflects that updated wording.

Kayn, Unleashed

Kayn, Unleashed #182/167 is the fifth Radiance HEARTSTEEL card.

Kayn, Unleashed originally appeared in Origins as #189/298. It is a 6-Energy, 6-Might Chaos Champion Unit with Ganking and an ability that can prevent Kayn from taking damage after he has moved twice during the turn.

The HEARTSTEEL card gives Kayn, Unleashed its first alternate printing currently documented for Riftbound.

Sett, Kingpin

The six-card checklist ends with Sett, Kingpin #183/167.

Sett, Kingpin originally appeared in Origins as #240/298. It is an Order Champion Unit that costs 4 Energy, has 5 Might, and gains additional Might for each buffed friendly unit at its battlefield.

Like Ezreal, Sett has more than one Riftbound card. The HEARTSTEEL printing is specifically Sett, Kingpin, not Sett, Brawler.

What Are Riftbound HEARTSTEEL Overnumbered Cards?

The six HEARTSTEEL cards are part of Radiance's Overnumbered lineup.

Radiance's standard collector numbering runs through 167/167, while the HEARTSTEEL cards are numbered 178/167 through 183/167.

Riot lists Overnumbers among the premium treatments that can appear in Radiance booster packs. Radiance also gives its nine new Legends Overnumbered variants, with artist-signed versions available for those Legend cards.

The HEARTSTEEL cards form their own six-card collector group:

K'Sante, Aphelios, Ezreal, Yone, Kayn, and Sett.

Are There Signed Riftbound HEARTSTEEL Cards?

Yes. Riot has announced HEARTSTEEL Overnumbered and Overnumbered Signature cards for Riftbound: Radiance.

The six cards listed above are the standard HEARTSTEEL Overnumbered versions numbered 178/167 through 183/167.

We are not counting signed treatments as additional unique HEARTSTEEL cards in this six-card checklist. The exact signed collector numbers and complete signature breakdown should be added once Riot has fully documented those versions.

Which Riftbound Radiance HEARTSTEEL Card Is the Biggest Chase?

There isn't a reliable market leader yet because Riftbound: Radiance does not release until October 23, 2026, and the new HEARTSTEEL printings do not yet have established post-release markets.

K'Sante, Courageous stands apart because it is the only card in the group whose standard printing is also from Radiance. The other five HEARTSTEEL cards bring existing Origins or Spiritforged cards back with new artwork.

Kayn also has a collector distinction because the HEARTSTEEL version is the first alternate printing currently documented for Kayn, Unleashed.

Actual collector demand should become much easier to judge once Radiance releases and singles begin trading consistently.

When Does Riftbound: Radiance Release?

Riftbound: Radiance releases October 23, 2026.

The HEARTSTEEL cards are part of the set's Overnumbered collector lineup alongside Radiance's new Legend variants and other premium treatments.
