Why this duo works
Alistar supplies reliable airborne setup with Pulverize(Q) and Headbutt(W), letting Yasuo use Last Breath(R) without first stacking his own Steel Tempest(Q) knockup. That gives Yasuo a fast follow-up to Alistar's engage and extends the crowd-control window for the team.
Measured in High Elo: this duo wins 1.3pp more often than expected over 1,159 games.
Playing the duo
Alistar's Pulverize(Q) and Headbutt(W) can each create an airborne target, which satisfies the airborne condition for Yasuo's Last Breath(R).
How to play as Yasuo
Hold Last Breath(R) for Alistar's airborne setup instead of waiting to stack your own Steel Tempest(Q) tornado. Follow the knockup quickly while Alistar's target is still in range.
How to play as Alistar
Use Pulverize(Q) or a Headbutt(W) that leaves the target within Yasuo's range, then ping the target so he can follow with Last Breath(R).
