Yorick vs Irelia

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.

Don't stand near your low-health minions: Bladesurge (Q) resets when it kills, so she chains dashes from minion to minion until she reaches you.

As soon as the first blade of Flawless Duet (E) lands, change direction: the stun only hits enemies caught between the two blades.

Take your trades when Ionian Fervor (passive) isn't stacked: she builds stacks with her abilities, and at max stacks her autos deal more damage.

Save your burst for after Defiant Dance (W): while charging, she takes much less damage, but she can't do anything else.

Dodge Vanguard's Edge (R): its blades make you Unsteady, which resets Bladesurge (Q) on you, and the cage they form damages and slows anyone who crosses it.
