Why this duo works

Stand United(R) lets Shen shield Kai'Sa and teleport to her when she commits with Killer Instinct(R), giving her follow-up protection and bringing Shen's taunt into the fight. Kai'Sa player discussions specifically recommend Shen for his ultimate shield and peel.

Playing the duo

Stand United(R) shields Kai'Sa and teleports Shen to her, while Shen's Shadow Dash(E) taunts enemies; allied immobilizing effects add Kai'Sa's Plasma stacks.

How to play as Shen

Use Stand United(R) on Kai'Sa as she enters a marked fight, then taunt nearby enemies with Shadow Dash(E) so she can follow with attacks and stack Plasma.

How to play as Kai'Sa

When you have a visible marked target and a safe entry, coordinate Killer Instinct(R) with Shen's Stand United(R) so he can shield and follow you into the fight; his players specifically recommend Shen's R for Kai'Sa's protection and peel.
