- Riftbound Radiance Seraphine anchors the set's Magic-attribute, spell-synergy archetype.
- Her power scales with Rhythm, the mechanic that counts Spells played each turn.
- Pair her with low-cost instants like Sonata of Swiftness and Stage Lights.
- Melody chains let you cast free follow-up spells and trigger Rhythm twice as fast.
- She excels against midrange, but struggles versus fast Noxus aggro burn.
Seraphine in the Radiance Set
Seraphine is one of the most anticipated Champion additions in Riftbound Radiance, the fifth expansion of Riot Games' League of Legends trading card game, releasing worldwide on October 23, 2026. As a music-themed set built around rhythm and melody mechanics, Radiance is practically tailor-made for the Starry-Eyed Songstress — she sits at the center of the expansion's Magic-attribute, spell-heavy playstyle.
Radiance introduces 180 cards and 9 new Legends, and its signature keywords — Rhythm, Melody, Encore, and Concert — all reward players for chaining spells in sequence. Seraphine converts every spell you cast into board value, making her the natural flagship for this archetype alongside fellow spell-synergy Champion Sona, Maven of the Strings.
Radiance launches on 2026-10-23 with Booster Boxes ($143.99), a Two-Player Starter Set ($29.99), Preconstructed Champion Decks ($19.99), and a Collector Booster Bundle ($59.99). Check the official site at riftbound.gg for confirmed Seraphine product reveals.

Core Mechanics: How Seraphine Synergizes with Rhythm
Radiance's new keywords define how a Seraphine deck wins. Understanding each one is essential before you shuffle up.
Rhythm
Counts Spells played this turn. Rhythm 2 bonuses trigger on your second Spell — Seraphine decks hit this threshold almost every turn with cheap instants.
Melody
When played, lets you immediately cast a Spell from hand costing equal or less mana, for free — one extra Rhythm trigger per turn.
Concert
Cards that count as both a Unit and a Spell — playing a Concert unit feeds Seraphine's spell payoffs while building a board.
Encore
Destroyed units return next turn with 1 Health and no keywords — your value engines get one final encore.
The practical chain looks like this: open with Sonata of Swiftness (Spell 1, grants Quick Attack), follow with Stage Lights (Spell 2, draws and pings), then drop a Concert unit — you've banked three spell triggers in a single turn while developing the board.
| Card | Rarity | Cost | Role in Seraphine Decks |
|---|---|---|---|
| Sonata of Swiftness | Common | Low | Rhythm enabler, grants Quick Attack to two allies |
| Stage Lights | Common | Low | Card draw + damage, keeps the chain going |
| Rhapsody of Valor | Epic | Mid | +2/+2 and Barrier; Overwhelm at Rhythm 2 |
| Eternal Duet | Rare | 4 | Ongoing drain engine with Melody potential |
| Virtuoso Recital | Epic | Mid | Up to 3 damage hits scaling with spell variety |
Rhythm counts Spells played this turn, not across the game. Sequencing matters — dump cheap spells before your payoffs, not after.
Building a Seraphine Deck: Step by Step
A standard Riftbound deck is 40 cards with up to 3 copies of each card, built around one or two Champions. Here's how to assemble a Seraphine list from scratch.
Commit to the Spell Plan
Build around a single Champion and match every card to the game plan. For Seraphine, that means roughly 18–22 Spells and Concert cards, keeping curve costs low so you can cast multiple spells per turn.
Load Up on Cheap Enablers
Max out Sonata of Swiftness and Stage Lights. Commons are cheap to acquire, and they consistently hit Rhythm 2 by turn three.
Add Payoff Spells
Include Rhapsody of Valor and Virtuoso Recital — these cards convert an active Rhythm count into immediate board swings and damage.
Fill the Board with Concert Units
Concert units double as Spells, so every unit play still advances your engine. They also block aggro decks while you assemble your combo turns.
Test Against the Meta
Pilot the list against Noxus Aggro and Demacia Midrange. Tune removal counts based on whether you face more swarms or single large Champions.
Start from the Radiance Preconstructed Champion Deck ($19.99) if it features a music Champion, then swap in Seraphine and her enablers from packs or trades — tournament-legal out of the box.
Matchups and Meta Positioning
Based on the current Radiance environment — dominated by Jinx/Darius aggro, Garen/Lux midrange, and Ashe/Leona control — spell-synergy decks like Seraphine occupy a flexible mid-tier spot that rewards skilled sequencing.
| Matchup | Difficulty | Game Plan |
|---|---|---|
| Noxus Aggro (Jinx/Darius) | Hard | Trade early, use Barrier from Rhapsody to blunt overwhelm damage |
| Demacia Midrange (Garen/Lux) | Even | Out-value with Eternal Duet drain; remove Garen before he scales |
| Freljord Control (Ashe/Leona) | Favorable | Spell chains dodge Frostbite attack reduction; burn the Nexus directly |
| Radiance Tempo (Leona/Yasuo) | Even | Concert units survive stun locks better than pure spell decks |
Against aggro, hold Sonata of Swiftness for defensive Quick Attack trades. Against control, save Virtuoso Recital for their healed champions — spell damage ignores the board entirely.
Seraphine Deck Milestones:
- Acquire 3 copies of Sonata of Swiftness and Stage Lights
- Hit Rhythm 2 on three consecutive turns in practice games
- Pull or trade for a full Seraphine Champion playset
- Chain a Melody cast into a free Rhapsody of Valor
- Win a local event with the finished list
