Playing against Corki

How to counter and exploit weaknesses

1

The majority of Corki's damage is magic — buy MR even though he's an ADC.

2

The Package is visible (he glows when he has it) — respect his engage range when he's picked it up.

3

Without his W, Corki is immobile — force fights when his dash is on cooldown.

4

He's weak before Trinity Force — punish him in the early game.
