Thresh vs Camille

Open with Flay (E) before Death Sentence (Q): the slow makes the hook much easier to land.

In lane, space out your autos: Flay (E) charges them passively, and the longer you wait between two autos, the more damage they deal.

Don't recast Death Sentence (Q) on reflex: the target is already being pulled toward you, and jumping on them often exposes you for nothing.

Throw Dark Passage (W) toward an ally in trouble before they need it: they can click it to come back to you, with a shield.

Place The Box (R) right after a successful hook: to escape, the target has to break a wall, and the first wall broken slows them and deals full damage.

Take a trade after her Hookshot (E): it's her only dash before level 6, on a 16 to 12 second cooldown.

When she latches onto a wall with Hookshot (E), step out of her line: she has 1 second to leap, and the landing stuns nearby champions.

Back off after the first Precision Protocol (Q) attack: if the second comes after a short delay, it hits harder and part of it ignores your armor.

Save your spells to fight inside The Hextech Ultimatum (R) rather than to flee: the trapped target can't leave the zone while it lasts.
