Riftbound Origins Competitive Season Retrospective
How Kai’Sa and Master Yi centralized early play, how Annie broke through in the West, and what Shanghai, SCGCon, and Houston taught the first global format.
Origins had to solve Riftbound in public. Early City Challenges suggested a wide field, but the largest events quickly exposed two exceptionally reliable plans. Kai'Sa and Master Yi defined the first weeks; Annie's western rise and Houston title finally complicated that story.
This is a historical retrospective. Official event facts and decklists come from Riot's coverage; Riftarc analysis explains the movement between events.
Before global release: Kai'Sa establishes the baseline
The pre-release tier list placed Kai'Sa clearly on top after strong Chinese City Challenge results. Master Yi and Viktor remained high despite not converting every event, while Sett and Annie showed promise. The useful early signal was consistency: Kai'Sa's standalone units and flexible answers required less metagame precision than narrower plans.
Shanghai: the format concentrates
The Shanghai National Open produced the season's starkest result. Four Kai'Sa decks and four Master Yi decks made up the entire Top 8, and the two Legends represented more than 72% of Day 2. Riftarc's review argued that common counterplay had not materialized because both decks combined efficient threats, card quality, and recovery.
Weekly reports after Shanghai kept Kai'Sa in S Tier. Master Yi held second, while Teemo, Ahri, Viktor, Sett, and Annie traded places behind them. Smaller events showed more variety, but the highest-reward tournaments reduced the appetite for experimental choices.
The western challenge: SCGCon and a rising Annie
SCGCon Las Vegas drew 386 players. Kai'Sa was 38% of the field and placed four copies in the Top 8. Annie put two decks into the Top 4, while Master Yi missed the final despite being the second-most popular Legend.
That result made Annie the strongest western challenger. Her extra-rune pressure and ability to keep reactive resources open attacked the format differently from the Chinese Master Yi builds. Week 5 and Week 6 reports showed Kai'Sa still first but increasingly vulnerable, with Sett also improving.
Houston: Dhawally turns momentum into a title
Riot's first North American Regional Qualifier coverage recorded all 16 legal Champion Legends on Day 1 and ten on Day 2. The event drew 1,123 players in Riftarc's recap. Kai'Sa occupied roughly a third of the field but converted only two Top 8 spots. Dhawally won with Annie, which also took three of the Top 4 places.
Houston's Best-Of program published a leading deck for all 16 Champions, preserving a much broader picture than the Top 8 alone. That matters: a season can be centralized at the top while still containing useful, proven lists for local play.
The final Origins picture
Riftarc's last pre-Spiritforged snapshot placed Kai'Sa and Annie in Tier 1. Master Yi remained foundational, and Miss Fortune had finally recorded a major win. The season's durable lessons were:
- consistency dominates an unsolved format before targeted counterplay exists;
- regional preferences can produce different “second-best” decks;
- popularity and conversion must be read together;
- one Top 8 does not erase six weeks of evidence, but repeated conversion can change a tier quickly.
The individual plans are compared in the aggro and midrange guides. Spiritforged's answer to this field begins in the next season retrospective.
Verdict
Origins began as Kai'Sa versus Master Yi and ended with Annie proving the West had found another route. The first season taught Riftbound players to distrust raw popularity, value repeatable battlefield fundamentals, and wait for more than one weekend before declaring a format solved.
