DSG Prismaticism won the September 26 Los Angeles Regional Qualifier on Rengar, Pridestalker, over Xeno's Irelia, Blade Dancer. The public event record lists 2,165 players in the Constructed event and the completed final. Riot's Los Angeles preview confirms that this was the final 2026 Regional Qualifier, and Riot's September ban update confirms that Ekko, Recurrent and Stacked Deck became illegal on September 18.
Public bracket coverage reports a Top 8 made up of two Irelia, two Azir, two Rengar, one Master Yi, and one Ornn. That is the clearest current competitive signal, but it remains reported placement data rather than a Riot recap with a complete decklist and match-data archive.
What Los Angeles Confirms
The strongest facts available are the Rengar win, the Irelia final, the 2,165-player event record, and the reported Top 8 composition. Riot's ban explanation connects Stacked Deck to Kennen's consistency and says the intended result was to slow the engine without destroying its core strategy. Los Angeles is therefore the first large US test of that adjustment.
Do not turn the bracket into a tier list. A Top 8 tells us which shells survived the hardest rounds; it does not tell us field share, win rate, conversion rate, or the exact cards in every list. Use it to choose gauntlet reps.
Rengar Is the New US Trophy Signal
Rengar is now the direct proactive-pressure test. The practical question is whether your opening can fight for a battlefield without trading away the entire hand, then survive the first reaction-speed, Ambush, or reposition turn. That is a matchup role, not a claim about an unverified Los Angeles list.
Read the Rengar counter guide, verify current card text in the card database, and build a test version in the builder. Do not copy an unknown tournament package.
Irelia Is the Most Repeatable Emerging Signal
Irelia reached the Los Angeles final and occupied two reported Top 8 seats. A preliminary same-day China report also lists Irelia wins in Beijing and Shenyang. The events are not directly comparable, but the repeat signal is enough to make Irelia a primary battlefield-tempo test.
The useful takeaway is not a card-for-card list. It is whether your deck can contest a flexible battlefield plan without spending its best answer on the first visible threat. Use the Irelia counter guide and Riftbound Counters to turn that question into matchup reps.
Azir Brings the Gear Engine Back to the Front
Azir also occupied two reported Top 8 seats. That makes the Emperor of the Sands a primary engine test alongside Rengar and Irelia. Azir asks whether you can pressure before Equipment count becomes a token engine and still answer the carrier that actually scores.
Two Top 8 seats do not prove a universal matchup advantage or validate identical lists. Use the Azir counter guide, the card database, and the decks library to test the gear-and-token role without inventing counts.
Master Yi and Ornn Keep the Field Honest
Master Yi and Ornn each reached one reported Top 8 seat. Master Yi remains the committed tall-threat check: can your deck save one clean reset for the unit that actually decides the battlefield? Ornn remains the gear check: can you contest before the equipment engine creates a protected carrier?
Use the Master Yi guide and Ornn guide to structure those games. The point is not to call either list tier one from a single result; it is to stop a gauntlet built only for the newest trophy.
Kennen Missed the Reported Top 8, but the Matchup Is Not Solved
The useful headline is not 'Kennen is gone.' It is 'Kennen did not qualify for the reported elimination bracket.' Riot did not ban Kennen. Riot banned the consistency tools that had made the engine too smooth, and the reported Los Angeles Top 8 shows that the post-ban field rewarded other shells in this event.
Keep Kennen in the gauntlet, but change the question. Can your anti-Kennen cards also contest Rengar, Irelia, and Azir? If not, your preparation may be too narrow. The dedicated Kennen counter guide covers the post-ban benchmark without treating one missing Top 8 as a solved matchup.
China Adds a Smaller Watchlist
A preliminary public report on five September 26 China City Challenges lists Irelia winning Beijing and Shenyang, with LeBlanc winning Chongqing, Jayce winning Zhongshan, and Lucian winning Zhengzhou. The combined sample is smaller than Los Angeles and winner-focused, so use it as supporting context rather than a replacement for Regional-scale evidence.
The two Irelia wins are the strongest part of that signal. LeBlanc, Jayce, and Lucian belong in the watch queue, not in a claim that their unverified city-challenge lists are the current format standard. The LeBlanc guide, Jayce guide, and Lucian guide keep those matchups role-based.
US Testing Queue After Los Angeles
- Rengar: the reported Los Angeles champion and direct proactive-pressure test.
- Irelia: the reported finalist, second Top 8 seat, and two smaller China wins.
- Azir: two reported Los Angeles Top 8 seats and a different engine axis.
- Kennen: the ban-target benchmark; one missing Top 8 does not solve it.
- Master Yi and Ornn: the reported tall-threat and gear-engine checks.
- LeBlanc, Jayce, and Lucian: smaller-sample watchlist stress tests, not proven tier-one recommendations.
Use Riftbound Counters to map those jobs, the builder to keep separate test versions, the card database to verify exact wording, and Riftbound decks to compare public shells without treating them as canonical.
What We Know and What We Do Not
Confirmed by Riot or the public event record: the September 18 ban effective date; Los Angeles as the final 2026 Regional Qualifier; the 2,165-player Constructed event; and Rengar winning the final over Irelia.
Preliminary public result data: the reported Top 8 composition and the five-event China City Challenge winner list.
Not established: a definitive best deck, Los Angeles field shares, win rates, conversion rates, complete official decklists, or whether the China winners repeat at a larger event.
Bottom Line
Los Angeles gave the post-ban US meta a champion and a broad shortlist. Rengar supplies the pressure test, Irelia the ready-engine test, Azir and Ornn the gear-engine test, Master Yi the committed-threat test, and Kennen the benchmark for whether the ban changed your preparation. China adds Irelia, LeBlanc, Jayce, and Lucian as smaller-sample questions. That is enough to change testing and not enough to publish an autopilot list.
