Kennen wins 60% in Los Angeles — and 85% against Jayce

by Riccardo Emanuele Eustor·Riftbound Zone

With day 1 of the Los Angeles Regional Qualifier in the books, the match data tells a different story from the registration sheet. Kennen, Heart of the Tempest finished at a 60% win rate across 921 games, the best mark among the top decks, and took 85% of its head-to-head games against Jayce, Defender of Tomorrow. Irelia is still the most played Legend but sits at 54%, with Jayce at 51%. The figures come from a tracking-app screenshot posted on r/riftboundtcg by u/nic_bolas: they are not official Riot numbers.

The numbersMost played is not best performing

Going in, the snapshot of the field said no Legend cleared 9% of the entries and that Irelia, Blade Dancer was the most common pick. After a day of actual games, the win-rate table looks nothing like it: Kennen, Heart of the Tempest leads at 60%, while Irelia — who played more games than anyone else, 965 of them — lands at 54%.

The heaviest number belongs to Jayce, Defender of Tomorrow. It was the surprise of the pre-Regional and it is still the third most registered deck on day 1, but on the table it finished at 51%, essentially a coin flip. Anyone who picked it expecting a structural edge did not get one.

Head to headKennen beats Jayce 85 times out of 100

The matchup matrix explains where Kennen's 60% comes from. Against Jayce the result is off the chart: 85% across 72 games, barely ten losses in the whole day. Kennen sits at 63% against LeBlanc, Deceiver over 72 games, 55% against Irelia over 93, and 60% against Akali, Rogue Assassin over 41. The only deck holding the line is Rengar, Pridestalker, dead even at 50% across 51 games.

Jayce collects its points elsewhere: 61% against Rengar and 78% against Akali. Against the other three top picks it is underwater — 41% versus Irelia, 41% versus LeBlanc, 15% versus Kennen. That is the profile of a deck that punishes the long tail of the field and pays the bill at the top tables, which is exactly where Kennen tends to be.

The outlierVex at 56%, just not against the top two

Vex, Gloomist posted the second-best mark of the day at 56% across 466 games, and its shape is the mirror image of Kennen's. It hits 79% against LeBlanc over 28 games and 61% against Rengar, but it stalls the moment it meets the two most common decks: 37% against Irelia over 54 games, 40% against Kennen over 55. It beats almost everything except what it runs into most often at the top tables.

A caveatA screenshot, not a press release

As with the field breakdown, these numbers did not come from Riot: they are a tracking-app screenshot shared by a player on Reddit. The matrix is internally consistent — every matchup is complementary to its mirror — and the totals match the size of the event, but the data is uncertified and covers day 1 only. Sunday can move it, especially in the rows with small samples.
