Wukong vs Jax

Engage with Nimbus Strike (E), then Crushing Blow (Q): the dash gives you attack speed, and Crushing Blow shreds your target's armor before your Cyclone (R).

Stay in close when you fight: Stone Skin (passive) increases your armor and health regen as long as you're fighting champions or monsters.

Cast Warrior Trickster (W) to escape or dodge a key spell: you dash and turn invisible for a moment, and your clone stays in place to fool the enemy.

Recast Cyclone (R) right after the first: the spell can be cast twice, and each spin knocks nearby enemies into the air again.

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.
