Zeri vs Twitch

Aim each Burst Fire (Q): it's your main attack, reaching 700 range and hitting the first enemy in its line.

Aim Ultrashock Laser (W) at a wall: the pulse becomes an area laser that slows and critically strikes champions.

Aim Spark Surge (E) at a wall: you vault over it, much farther than with the dash alone, and your Burst Fire pierces for a few seconds afterward.

Cast Lightning Crash (R) near a champion: hitting them gives you attack speed and move speed, and each hit on a champion extends the effect. Attack while backing off.

Get out of the Venom Cask (W) cloud fast: it slows you and adds a Deadly Venom stack every second, which powers up his Contaminate (E).

Ward your brushes and place a Control Ward on his paths: it reveals camouflaged enemies, and Ambush (Q) lets him reach you unseen.

As soon as he comes out of the Ambush (Q) camouflage, focus him with your allies: he's fragile and has no dash to escape.

During Spray and Pray (R), get out of his extended range until the effect ends: his bolts pierce every enemy, so hiding behind an ally won't protect you.
