Ivern vs Xin Zhao

Place your groves, then go gank while they grow: Friend of the Forest (passive) lets you free the camp without fighting it once the grove is fully grown.

After landing Rootcaller (Q), ping your team: allies who attack the rooted target dash into attack range, and you can dash to the target by recasting.

Cast Triggerseed (E) on the ally who engages: the shield explodes after a moment and slows enemies around them.

Recast Daisy! (R) to give her a target: her 3rd consecutive auto on the same champion knocks every enemy hit into the air.

Get out of the line of the Wind Becomes Lightning (W) thrust: it slows you and marks you as Challenged, which extends the range of Audacious Charge (E) on you.

If you have CC, use it during Three Talon Strike (Q): without his three autos, there's no knock-up, and his other cooldowns don't go down.

After Audacious Charge (E), keep your distance: it's his only dash to get back on you, and without it he has to walk up to you.

After Crescent Guard (R), don't hit him from range: for a moment, he ignores damage from outside the swept zone. Back off, or hit him from inside it.

If you survive his first minutes, play for time: Xin Zhao is strongest early on, through his ganks and skirmishes.
