Yone vs Cho'Gath

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.

Keep moving against him: Rupture (Q) strikes an area on the ground, and an enemy standing still takes a knock-up, damage and a slow.

Punish him when he goes for last hits: Carnivore (passive) restores health and mana for each unit he kills, and he lasts a long time in lane if you let him farm.

If you have range, keep your distance: his kit has no dash, only the slows from Rupture (Q) and Vorpal Spikes (E).

Don't stay in melee range at low health when Feast (R) is up: its true damage ignores your resistances, even if you're a tank.
