Cho'Gath vs Yone

Aim Rupture (Q) where your opponent is going, not where they are: the area knocks them into the air and slows them.

Follow a successful Rupture (Q) with Feral Scream (W): the silence stops them from casting spells, dashes included.

Cast Vorpal Spikes (E) before a trade: your next 3 autos launch spikes that slow enemies in front of you and deal damage based on their max health.

Finish with Feast (R) as soon as it's up: each kill gives you permanent max health, but minions and non-epic monsters only give a limited amount.

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.
