Thresh vs Braum

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.

Back off when you have Concussive Blows (passive) stacks on you: his allies' autos add stacks too, and the 4th stuns you.

Catch him when he's far from his allies: Stand Behind Me (W) only leaps to an ally, minions included, and without one nearby he has no dash.

Don't shoot into Unbreakable (E): it intercepts your projectiles. Go around it, use AoE spells, or wait for him to lower his shield.

Don't line up with your allies in front of him when he has Glacial Fissure (R): it hits every enemy along its line and around him with a knock-up.
