T1 vs CTBC Flying Oyster Worlds G1: Kai’Sa Punishes Jhin
T1 face CTBC Flying Oyster at Worlds in Game 1, where Doggo’s Kai’Sa brings a 69% global WR against Jhin and challenges T1’s engage draft.


TL;DR: T1 face CTBC Flying Oyster in Worlds Game 1, with the draft model giving T1 a 57% win probability to CTBC Flying Oyster’s 43%. The defining lane statistic is Doggo’s Kai’Sa, which has a 69% global WR against Jhin over 32G—a dangerous counter to Peyz’s long-range setup if CTBC can protect its carry and reach fights on its terms.
Doggo’s Kai’Sa has a 69% global WR against Jhin over 32G, so CTBC Flying Oyster has paired a strong lane answer with a clear target: blunt Peyz’s long-range pick potential before T1 can start a fight. Whether that pressure is deliberate or simply the best available response, it only pays off if CTBC can withstand Vi and Rakan’s engage and keep Kai’Sa alive through the first lockdown.
Compositions: T1 vs CTBC Flying Oyster
T1’s Ambessa, Vi, Galio, Jhin, and Rakan form a direct engage and pick composition. Vi can lock down a priority target, Galio can follow with Hero’s Entrance, and Rakan gives T1 another way to start a fight. Jhin adds long-range follow-up and can help secure picks, though he is less comfortable as the primary sustained damage source in a front-to-back fight. T1 want to create skirmishes in the mid game and snowball a numbers advantage into objectives.
CTBC Flying Oyster have Rumble, Qiyana, Ryze, Kai’Sa, and Alistar: a more explosive skirmish and teamfight setup. Rumble’s area damage and Alistar’s engage can create space for Qiyana to punish grouped targets, while Ryze supplies side-lane pressure and later-game scaling. CTBC need to avoid being caught by Vi first; if they reach a fight together, their layered damage can turn T1’s commitment against them.
Key Picks and Stats
In top lane, Doran’s Ambessa has a 48.8% global WR over 1409G and a 50.0% Worlds WR over 10G. Rest’s Rumble stands at 52.3% over 1614G globally, but 38.5% over 13G at Worlds. Ambessa is at 51.6% against Rumble over 273G globally, while Rest’s Worlds matchup figure is 66.7% over 3G. That tiny Worlds sample favors Rest, but the broader record is close.
Oner’s Vi has a 53.1% global WR over 1320G and a 66.7% Worlds WR over 9G; his own Worlds record on the pick is 0.0% over 1G, with a 2.3 KDA. Shad0w’s Qiyana is 59.3% over 442G globally and 63.6% over 11G at Worlds, yet Qiyana has only a 30.4% global WR against Vi over 23G. The matchup is a meaningful counter-pressure point for T1, despite Shad0w’s strong tournament form.
Faker’s Galio has a 47.9% global WR over 664G and a 66.7% Worlds WR over 6G; POUT’s Ryze is at 49.9% over 1735G globally and 50.0% over 4G at Worlds. Galio’s global WR against Ryze is 50.0% over 28G. In bot lane, Peyz’s Jhin is 45.2% over 1083G globally and 60.0% over 10G at Worlds; his Worlds record is 100.0% over 1G, with a 10.0 KDA. Doggo’s Kai’Sa has a 54.1% global WR over 375G and 68.8% against Jhin over 32G.
Keria’s Rakan has a 52.7% global WR over 768G and 33.3% over 6G at Worlds. Kino’s Alistar is 54.3% over 854G globally, 36.4% over 11G at Worlds, and 56.8% against Rakan over 111G. That lane matchup favors CTBC on the available global data.
Draft Edge
The pre-draft call expected T1’s B1 to be Vi if available; Oner got her. The anticipated bans—T1 targeting Rumble, Nocturne, and Akali, and CTBC considering Vi, Jayce, and Bard—cannot be verified from the supplied draft information. Rumble was left open for Rest. The standout departure from last night’s forecast is CTBC’s Qiyana: the pre-draft priority list highlighted Rumble, while Qiyana’s 59.3% global and 63.6% Worlds WR make her a credible high-impact choice.
T1 have the cleaner first-target sequence, and their model signals include a 60.8% Vi-versus-Qiyana matchup WR over 6G. CTBC’s best route is to use Rumble and Alistar to disrupt T1’s engage, then let Qiyana and Kai’Sa punish the resulting chaos. The model’s small edge to T1 fits that reliable initiation, though the Kai’Sa-versus-Jhin statistic makes the bot-side risk substantial.
Polymarket Market
Polymarket’s real-money Game 1 market gives T1 86% and CTBC Flying Oyster 14%; the Series market is T1 84%, CTBC 16%. The Series was T1 88% to CTBC 12% about 90 minutes before the match, a 4.0 percentage-point move against T1. The Game market is 2 percentage points more optimistic about T1 than the current Series market, a modest difference rather than a decisive split.
That confidence in T1 likely reflects the team’s overall strength and its Vi-led engage, while the smaller Series shift suggests some market caution. CTBC’s Kai’Sa matchup edge and Qiyana’s strong Worlds record offer plausible reasons not to treat the draft as a formality, even though the market still strongly favors T1.
Prediction
The draft model predicts T1 57% to CTBC Flying Oyster 43%. I would keep T1 narrowly ahead: Vi and Galio give them a straightforward way to start fights, and Vi’s matchup data against Qiyana is favorable. CTBC can upset that read if Doggo exploits the Jhin lane and Shad0w finds a clean follow-up; its lower team-form signal of 0.400 versus T1’s 0.500 is another reason to favor T1, but not to dismiss the counterpicks.
FAQ
Q: Can Doggo’s Kai’Sa punish Peyz’s Jhin in lane?
The matchup record points that way: Kai’Sa has a 68.8% global WR against Jhin over 32G. T1’s engage still makes positioning and protection crucial after lane.
Q: Does Oner’s Vi give T1 a clear answer to Shad0w’s Qiyana?
The model’s matchup figure gives Vi a 60.8% WR against Qiyana over 6G, and Oner has a 66.7% Worlds WR on Vi over 9G. His personal Worlds record is 0.0% over 1G, so that specific sample is far too small to outweigh the broader evidence.
