Why this duo works
Blitzcrank pulls an opponent into Xayah's range and adds a knock-up, giving her time to place feathers and follow with Bladecaller(E) for more damage and a root. Xayah players specifically praise Blitz's damage and crowd-control follow-up after a hook.
Playing the duo
Rocket Grab(Q) and Power Fist(E) keep a target close and controlled long enough for Xayah to lay feathers and recall them with Bladecaller(E) for a root; Xayah players describe Blitz as a strong partner because she can follow his hook with damage and crowd control.
How to play as Xayah
After Blitzcrank pulls a target, use Double Daggers(Q) and attacks to place feathers, then recall them with Bladecaller(E) for the root; Blitz's pull and knock-up give you a clear follow-up window.
How to play as Blitzcrank
Look for hooks on targets Xayah can reach and follow; her Bladecaller(E) can root after your pull and knock-up, but the catch is weaker if she cannot get close enough to place feathers.
