Yone vs Jax

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.

Take a short trade, then back off: Relentless Assault (passive) increases his attack speed with each consecutive auto.

During Counter Strike (E), back off instead of attacking: he dodges your autos, then stuns nearby enemies, dealing more damage per dodged auto.

Trade right after Counter Strike (E): it's both his defense and his only stun, and it has a 17 to 9 second cooldown.

In the late game, don't leave his split push unanswered: send someone to hold his lane, or force an objective on the other side of the map.
