Yorick vs Yone

Hit a champion or last-hit a minion with Last Rites (Q) to dig a grave: with three graves nearby, recast the spell to raise Mist Walkers from them.

Hit your target with Mourning Mist (E): your nearby graves keep raising Mist Walkers, the target loses armor, and your units rush toward them.

Trap your target in Dark Procession (W): the wall blocks enemies but not your allies, and your Mist Walkers hit them in the meantime.

After 10 seconds, recast Eulogy of the Isles (R) to send the Maiden of the Mist to push the nearest lane, but you lose a big part of your power.

Get out of his line after two Mortal Steel (Q) hits: the next one makes him dash forward and knocks the enemies hit into the air.

During Soul Unbound (E), avoid taking hits: when he snaps back, part of all the damage he dealt you is repeated.

If you have ground-targeted CC, place it on the body he left behind: when Soul Unbound (E) ends, he has to return there.

Judge his threat by his crit items more than his level: Way of the Hunter (passive) raises his critical strike chance, so each crit item does more for him.

In teamfights, don't line up with your allies in front of him: Fate Sealed (R) hits every enemy in a line and knocks them into the air toward him.
