Zac Jungle and Yasuo Mid win 54.2% of 3,025 Low Elo games together, +2.2 points vs expected, 2-patch window 26.19-26.20.

Researched on LoL patch 26.20. Tips are written to hold at any rank; stats come from Low Elo ranked games up to patch 26.20.

Why this duo works

Zac's Elastic Slingshot(E) and Let's Bounce(R) create airborne targets for Yasuo's Last Breath(R). Yasuo players cite Zac as one of his best jungle partners because he creates repeated ult windows, and Zac mains confirm Yasuo can follow their engage.

Playing the duo

Elastic Slingshot(E) knocks up enemies on landing, and Let's Bounce(R) knocks airborne enemies, giving Yasuo targets for Last Breath(R).

How to play as Zac

When Yasuo is in range, time Elastic Slingshot(E) or Let's Bounce(R) so he can follow with Last Breath(R); your knockups can create several chances for him to enter the fight.

How to play as Yasuo

Follow Zac after Elastic Slingshot(E) lands or Let's Bounce(R) starts, then use Last Breath(R) on a high-value airborne target instead of spending it before Zac's engage creates the opening.
