Why this duo works
Cho'Gath Q and Yone Q3 or R all create airborne windows, so one champion can set up the other's follow-up crowd control. Yone R can also pull enemies hit along its line together, giving Cho'Gath a better cluster for Q; the coordinated crowd control is especially useful in high-elo fights.
Measured in High Elo: this duo wins 1.4pp more often than expected over 1,004 games.
Playing the duo
Cho'Gath Q knocks up enemies in an area. Yone Q3 knocks up enemies in a line, and Yone R pulls enemies hit toward him while knocking them airborne, so either champion can start a crowd-control chain for the other.
How to play as Cho'Gath
When Yone has Q3 or R ready, place Cho'Gath Q under a clustered fight; its knockup gives Yone a clear follow-up window for R.
How to play as Yone
Coordinate Yone R to follow Cho'Gath Q's knockup and extend the crowd control. If you engage first with Yone Q3 or R, pull enemies into a tight group so Cho'Gath can land Q more reliably.
