Why this duo works
Sleepy Trouble Bubble(E) gives Jhin a safe window to land Deadly Flourish(W): Zoe's hit puts the target to sleep, then Jhin's first hit breaks the sleep and can root the recently damaged target. That chain control lets the duo convert Zoe's catch into Jhin's burst without needing to win a long fight.
Measured in High Elo: this duo wins 1.5pp more often than expected over 1,038 games.
Playing the duo
Sleepy Trouble Bubble(E) puts a target to sleep after its drowsy delay, and Deadly Flourish(W) roots a champion recently damaged by Jhin or an ally; Jhin can follow Zoe's sleep with a root.
The first hit that breaks Zoe's sleep deals increased damage, so Jhin can use a shot or Dancing Grenade(Q) as the wake-up hit.
How to play as Jhin
Wait until Zoe's E has put the target to sleep, then use W or a shot to wake them and continue the control chain instead of firing into the drowsy window too early.
How to play as Zoe
Land Sleepy Trouble Bubble(E) and call the sleep timing so Jhin can line up Deadly Flourish(W) before the target wakes; the root can extend the catch after the wake-up hit.
