Yone vs Swain

Hit twice with Mortal Steel (Q), minions included, to charge the next one: it makes you dash forward and knocks the enemies hit into the air.

Cast Spirit Cleave (W) on several champions at once: it deals damage based on their max health, and your shield grows with the number of champions hit.

Cast Soul Unbound (E) to engage: when it ends, you snap back to the body you left behind, and part of the damage you dealt to champions is repeated.

Cast Fate Sealed (R) through several enemies: everyone in the line is hit and knocked into the air toward you, and you reappear behind the last champion hit.

Get out of the Nevermove (E) path as it comes back: it only roots on its return to Swain, then he can pull each rooted champion to him.

Leave the area as soon as Vision of Empire (W) appears: it strikes and slows 1.5 seconds later, and each champion hit gives him a Soul Fragment.

During Demonic Ascension (R), back off and hit from range if you can: he only drains nearby enemies, and his form ends when he stops draining.

If you have Grievous Wounds, apply it during Demonic Ascension (R): the drain heals him every second, and that healing keeps him alive.
