Graves vs Jax

Position with no minion between you and your target: each New Destiny (passive) auto fires 4 bullets that can't pass through units.

Cast Smoke Screen (W) on their carries: inside the smoke, they're slowed and can't see anything outside it for 4 seconds.

Fire Collateral Damage (R) with your back to the danger: the shot knocks you backward, enough to reposition while dealing damage.

Cast Quickdraw (E) often during your clear: it reloads a shell, gives armor and magic resist, and each bullet that hits lowers its cooldown.

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.
