Why Xayah is favored

With his cleanse down, Alistar's W+Q engage brings him into Xayah's feather zone. If she has laid feathers before he commits, Bladecaller(E) can root him on entry and Featherstorm(R) can avoid the follow-up, giving her a direct answer to his dive pattern.

How to play as Alistar

If Xayah has laid feathers between you and her, use Headbutt(W) to knock her out of that line before she recalls them; if Bladecaller(E) roots you, Unbreakable Will(R) can clear it.

Headbutt(W) displaces Xayah, which can move her out of the line between Alistar and her feathers before Bladecaller(E) returns them.

Unbreakable Will(R) removes crowd control already affecting Alistar, so he can clear a Bladecaller(E) root after it lands.

How to play as Xayah

Wait until Alistar has used Unbreakable Will(R) before relying on Bladecaller(E) to hold him; his ultimate removes the root. Keep Featherstorm(R) ready if you need to avoid his W+Q engage.
