Jarvan IV vs Wukong

Plant Demacian Standard (E), then cast Dragon Strike (Q) toward it: you fly to the flag and knock enemies in your path into the air.

Land an auto as soon as you reach your target: Martial Cadence (passive) adds damage based on their current health, then only triggers on them again after a few seconds.

Cast Cataclysm (R) on a carry who is away from their team: the arena is impassable, and you can recast to collapse it if it gets in your allies' way.

In teamfights, plant Demacian Standard (E) near the allies who are attacking: it gives them attack speed while they stay close to it.

Trade after Warrior Trickster (W): it's his best escape, and it has a 22 to 18 second cooldown.

When Warrior Trickster (W) turns him invisible, ignore the figure standing still: that's the clone, and the real Wukong just dashed off to the side.

When he has Cyclone (R), spread out from your allies: he spins in the middle of your team and knocks every nearby enemy into the air, twice.

If you have a way to escape, wait for his second Cyclone (R) to end: the spell can be recast once, and each spin knocks nearby enemies into the air again.
