The one and only Corki mid ret
Not Updated For Current Season
You can trade in early but you are not strong enough to handle someone in 1v1 in early game.So you should farm a lot in early because it is very easy as Corki since your Q+R combo kills the mage minions. In late try to make cathces with your packet and roam a lot to help other lanes and collect some kills/assists.
Personally i recommend to use Barrier and Flash but if you are confident enough teleport would do the work too.
About the build
Well guys i am not a huge corki player this season since the nerfs but beofre that i used to play a lot as him. Nowdays he is becoming better and better thanks to the item changes and i feel like this is the time for him to come back to the meta as a hybrid mid lane carry. I couldnt put him into any team role so i chose other because he is not ad or ap or assassin he is just a mid lane hypercarry who uses both magic and physical damage as his adavantage.
Pros / Cons
Pros: High damage outpot from a far in late. Good mobility.
Cons: Low damage output in early game. Squishy if you don't have W in early you are 99% dead if the enemy jungler ganks.
