Ambessa vs Cho'Gath

Weave an auto between spells: Drakehound's Step (passive) empowers it and refunds energy, while your three basic spells cost 70 each.

Hit with the edge of Cunning Sweep (Q): enemies caught by the edge take much more damage, and landing it readies Sundering Slam (Q).

Take a short trade: Cunning Sweep (Q), an auto, then Lacerate (E) with a dash backward, which adds a strike at the end of the dash.

Cast Public Execution (R) toward the enemy carry: you blink to the farthest enemy champion in the line you choose, nothing can stop you, and you suppress them.

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.
