Riftbound Radiance Spoilers: All Confirmed Cards & Legends

Radiance is the fifth set for the Riftbound TCG, and the spoiler season is now in full swing. Previews kicked off at RQ Los Angeles from September 25–27, 2026, and run through October 9, giving players a month of reveals before the worldwide release on October 23, 2026. This guide rounds up every confirmed Riftbound Radiance spoiler so far, from the full Legend roster to the standout Seraphine mechanic that has the community buzzing.

Video Highlights:

• Seraphine confirmed as a new legend with a spell-discount exhaust mechanic
• Her domains are yellow and blue, a proven competitive color pair
• Zero-energy spell casts are possible when three units are exhausted
• Champion unit synergy generates Recruit tokens on exhaust triggers

The biggest early spoiler centers on Seraphine, the Star-Eyed Songstress. Her legend text lets you exhaust her and three friendly units as an additional cost to play a spell, reducing that spell's cost by two energy — with a floor of zero. Community analysis from the reveal window suggests this could anchor a real competitive deck, and we break down why below.

Six Legends are officially confirmed for Radiance, with three more still unannounced as of late September 2026. Here is the full roster:

Seraphine's legend text reads: exhaust her plus three friendly units to reduce a spell's cost by two energy, down to a minimum of zero. The reduction is capped — you cannot exhaust six units for a four-energy discount — but the implications are significant.

Key points from the reveal analysis:

• Yellow and blue is a proven competitive shell, with established archetypes for Victor, LeBlanc, and Lux already in the format
• The discount applies on your opponent's turn too, enabling cheap reaction spells during combat
• Zero-energy casts catch opponents off guard when you appear tapped out
• Big spells like Time Warp (eight energy) and Singularity become far more accessible

Champion Unit Synergy

The revealed yellow epic champion unit costs five energy, has one might, and reads: when played or when it becomes exhausted, create one Recruit token in your base; it has plus one might for each other exhausted unit you control. Every time Seraphine exhausts herself to discount a spell, she generates more bodies — and more bodies mean more future discounts.

Beyond Seraphine herself, several existing cards interact strongly with her mechanic:
