Ekko vs Wukong

Throw Timewinder (Q) at a champion, then position so the device passes through them again on its way back: it expands into a slowing field, and the return hits again.

Hit with Timewinder (Q) out and back, and weave in the empowered auto from Phase Dive (E): the third hit triggers Z-Drive Resonance (passive), with bonus damage and speed.

Cast Parallel Convergence (W) where the fight will happen, then step into the sphere when it appears: you stun the enemies inside and gain a shield.

Engage, deal your damage, then cast Chronobreak (R): you return to where you were 4 seconds earlier, in stasis, and recover health based on what you lost.

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.
