The build here will give you power early game to get fed. Unless the enemy team is really fed he will not fall down late game. This build is for the AD Carry role.

Early game you want to make sure you are farming as much as possible and harassing with basic attacks and your Q. Corki's early game is so good he can take on most ad carries.

The Runes I chose are my personal preference but if you know any better runes for corki please let me know

I chose Flash so I can feel free to use my W to help in a fight, and I will still have an escape. I chose ignite to help with finishing off enemy champions.

This build can help you dominate early game.

The masteries I chose are just your standard adc masteries 21-9-0.
