Jinx vs Vel'Koz

Poke with Fishbones, the rocket launcher of Switcheroo! (Q), for its range and splash damage, then swap back to the minigun for long trades.

Fire Zap! (W) to kite the bruiser running at you or catch an enemy who's fleeing: it slows and reveals the first enemy hit.

Throw Flame Chompers! (E) in the path of their engage or their escape: they root the champion who steps on them and last 5 seconds.

In teamfights, focus the lowest-health target first: each takedown triggers Get Excited! (passive), a big boost to attack speed and move speed.

Fire Super Mega Death Rocket! (R) to finish a fleeing enemy rather than to start a fight: its damage grows with their missing health and over its first second of flight.

Get out of the line of Plasma Fission (Q) and watch its sides too: the bolt splits into two branches at 90 degrees when it hits a target or he recasts it.

Back off after taking two of his spells: at the third Organic Deconstruction (passive) stack, you take a burst of true damage.

If you can engage, go in after Tectonic Disruption (E): it's his only spell to push back someone charging him, and he has no dash to escape.

If you have a stun, a silence or a knock-up, save it for Life Form Disintegration Ray (R): any of them interrupts the ray.
