Riftbound Jayce Deck Guide: Aurora Mind-Body Build
The Aurora list only runs one unit, Elder Dragon, so the gear always finds it. Here's the deck that topped Jayce at RQ Los Angeles.
Our callJayce Aurora is a solid Tier 3 deck, not the Tier 1 threat it looked like in September. It was the third most-played legend at RQ Los Angeles and made Day 2 only a little more often than the field.
The Riftbound Jayce deck that wins is Jayce Aurora: a Mind-Body gear list whose only unit is Elder Dragon. Dazzling Aurora reveals cards until it finds a unit, so every trigger puts a free 12-cost Dragon into play. It's a real deck, but the September hype hasn't held up. Riftbound.gg now has Jayce in Tier 3, and it made Day 2 at RQ Los Angeles only slightly more often than the average deck.
Updated October 22, 2026: We replaced the September Tier 1 rating and the single-event win rate with Riot's official RQ Los Angeles and Singapore numbers and riftbound.gg's October 9 tier list, swapped in the top Jayce list from Los Angeles, and fixed the Dazzling Aurora and Gutter Palace descriptions against Riot's card gallery.
Jayce Aurora deck list
This is ASC Brandon's list from RQ Los Angeles (September 25 to 27). Riot's Los Angeles top-decks report ranks it first of the 153 Jayce players and 42nd overall.
| Copies | Card | Role |
|---|---|---|
| 3 | Dazzling Aurora | The engine: plays a free unit at the end of each of your turns |
| 3 | Elder Dragon | The only unit in the deck; turns every 1 damage into a kill |
| 3 | Platewyrm Egg | Energy ramp gear |
| 3 | Catalyst of Aeons | Channels two runes |
| 3 | Mobilize | Channels a rune |
| 3 | Promising Future | Each player plays one card from their top five, ignoring Energy costs (Power costs still paid) |
| 3 | Clairvoyance | Predict 5, draw 2 |
| 3 | Dredge Up | Draw 1, can be replayed from the trash |
| 3 | Bellows Breath | Deal 1 to up to three units at a location |
| 2 | Flurry of Blades | Deal 1 to every unit at battlefields |
| 2 | Rocket Barrage | Deal 4 to a unit in a base, or kill a gear |
| 2 | Sabotage | Takes a non-unit card from the opponent's hand |
| 2 | Gutter Palace | Alternate win condition |
| 2 | Garbage Grabber | Card draw from the trash |
| 1 | Sprite Burst | Two temporary 3 Might Sprites |
| 1 | Sprite Fountain | Temporary Sprite, then another when it dies |
Legend: Jayce, Defender of Tomorrow. Champion: Jayce, Brilliant Inventor. Battlefields: Forgotten Monument, Frozen Fortress, Sigil of the Storm. Runes: 8 Body, 4 Mind.
The Singapore Jayce that Riot ranked first of 57 (justmilkey) runs the same core with 7 Body and 5 Mind runes, one Gutter Palace instead of two, and Dragon Roost in place of Frozen Fortress.

How Jayce Aurora works
OGN-160
OGN-160Shop on TCGplayer Dazzling Aurora is a 9-energy Body gear: "At the end of your turn, reveal cards from the top of your Main Deck until you reveal a unit. Play it, ignoring its cost, and recycle the rest." It triggers every turn it stays in play, not just once.
UNL-118
UNL-118Shop on TCGplayer Elder Dragon costs 12 with 10 Might. "Any amount of your damage is enough to kill enemy units," and when it's played it deals 1 to up to one enemy unit at each location. Because it's the only unit in the Main Deck, Aurora never whiffs while a Dragon is left.
That's why the spells all deal 1. With a Dragon out, Bellows Breath and Flurry of Blades become board wipes, and Frozen Fortress deals 1 to each unit there at the start of every Beginning Phase.
Jayce himself speeds up the gear plan. 
VEN-149
VEN-149 Defender of Tomorrow pays 1 and exhausts to ready a gear, or two once Empowered. The champion, Jayce, Brilliant Inventor, readies something exhausted when he's played and the first time you play a non-token gear each turn. Readying Platewyrm Egg means extra energy on the turn you need nine.
Gutter Palace is the backup plan. At the start of your Beginning Phase, if you have exactly 4 cards in hand and exactly 4 units at battlefields, you win. Sprite tokens and its own Bird token help you hit the unit count when the opponent stops answering Dragons.
Mulligan and early turns
Riftbound opening hands are four cards, and you can set aside up to two. Keep ramp: Platewyrm Egg, Catalyst of Aeons, Mobilize. Put back Elder Dragon and Gutter Palace, which do nothing early. One Aurora in hand is fine if the rest of the hand ramps.
Forgotten Monument stops anyone scoring there until their third turn, which buys the setup time this deck needs.
Is the Jayce deck still good?
Image: ShonenTCG chart from Riot's official RQ Los Angeles top-decks report.
At RQ Singapore, Jayce was a sleeper. Only 57 players brought it, but 20 made Day 2, a conversion rate of 35% against 16% for the whole field. That's what put it in the September Tier 1 conversation.
At Los Angeles, everyone was ready for it. Jayce was the third most-played legend with 153 players, behind Irelia and Kennen. Only 33 made Day 2, 22% against 19% for the field, and none reached the Top 8. Riftbound.gg's write-up of the event said: "I expected Jayce to be a lot more menacing in Los Angeles, and possibly compete for a top 8 spot." Their tier list, updated October 9, has Jayce in Tier 3.
The players we read agree there's only one version worth taking to an event. u/dcrico20 put it plainly on r/riftboundtcg: "There's not a competitive Jayce build at the moment that doesn't involve Aurora and Elder." u/Xopstix added the budget reality in the same thread: "If you like Aurora's playstyle, Jayce is the best at it and there's no way around buying Elders and Auroras."
Boba Riftbound's full guide from October 8 goes deeper on the lines:
Our take
Jayce Aurora is a good deck that everyone now plans for. The Elder Dragon loop is real, and when it lands against a board of small units the game ends fast. But Kennen and LeBlanc both converted better at Los Angeles, and players brought answers. Radiance, Riftbound's fifth set, released on October 23, so watch whether it adds gear for Jayce or more answers to Aurora. If you want a Tier 1 deck today, read our Master Yi deck guide or check the Riftbound meta tier list. For what Radiance adds, see our Radiance set preview.
How we checked this: we read the Jayce lists and Day 1/Day 2 tables from Riot's official RQ Singapore and Los Angeles reports, computed conversion rates with scripts/sims/riftbound-rq-day2-conversion.py on October 22, and checked every card's text and type in Riot's card gallery.
