Riftbound Heartsteel Cards (Release Date and All Cards) - Riftbound TCG

Riot Games has officially revealed the music video for HEARTSTEEL's new track, "Live My Life," on the League of Legends and Riot Games Music YouTube channels. If you're a Riftbound player, there's more to this video than just the music. Riot snuck in a tease of brand new HEARTSTEEL-themed Riftbound cards, and they've now been officially confirmed for the upcoming Radiance set.

UPDATE: The Heartsteel Overnumber and OVN Signature cards have been officially confirmed for Riftbound Set 5: Radiance, dropping October 23, 2026.

Riftbound Heartsteel Cards

HEARTSTEEL is made up of six League of Legends champions: Ezreal, Sett, Yone, K'Sante, Aphelios, and Kayn. All six appear on cards teased during the "Live My Life" music video. Five of these champions already have printed cards in Riftbound. K'Sante is the exception, although his card has previously been teased, and he is expected to join the upcoming Radiance set.

The cards shown in the video feature HEARTSTEEL-themed artwork, and some of them are clear enough to reveal details such as their cost, type, and card text. This suggests that these aren't simply promotional graphics created for the music video.

Update: Since then, Riot has officially confirmed that all six HEARTSTEEL champions will be getting Overnumber and OVN Signature cards in Riftbound Set 5: Radiance. You'll be able to get your hands on them when Radiance releases on October 23, 2026.

Here's a screenshot from the official video showing the six teased cards:
