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

Sejuani can start Yasuo's ultimate with Arctic Assault(Q), and Yasuo's melee attacks quickly add Frost stacks for Permafrost(E). Together they can chain a knockup into another stun and keep a target locked down.

Playing the duo

Arctic Assault(Q) knocks a champion airborne for Yasuo's Last Breath(R), while Yasuo's melee basic attacks apply Sejuani's Frost stacks toward Permafrost(E).

Sejuani can freeze and stun a target with Permafrost(E) after Frost stacks are applied, extending the control window after Yasuo's airborne engage.

How to play as Sejuani

Use Arctic Assault(Q) on a target Yasuo can reach for Last Breath(R), then keep attacking to finish Frost stacks and stun with Permafrost(E).

How to play as Yasuo

Follow Sejuani's Arctic Assault(Q) with Last Breath(R), then keep basic attacking the same target to help Sejuani finish her Frost stacks for Permafrost(E).
