Corki

The Package (passive) gives you a huge dash every few minutes — use it for teamfight engages or surprise roams.

Your damage is ~80% magic despite auto-attacks — crit builds with AP penetration are effective since you shred players who stack armor.

R rockets (Missile Barrage) have a big rocket every 3 charges — save it for poke or waveclear.

W (Valkyrie) is your only escape — don't use it offensively unless you have the Package.

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

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

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

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