Essence Reaver is good but only for CDR and if you rush it and you don't get Triforce. If you get Triforce you get rid of the mana problems that Essence Reaver solves although the CDR which lets you charge more shots for your ult and lowers the CDR on your only escape tool makes it very useful espescially if you get Black Cleaver ontop of that.

Sorcerer's shoes is sort of odd though. Corki's build that but I need the early AS a lot more and Corki has no AS steroids so I find it much easier to get the Greaves than to get the shoes which well. If you buy AD pen or have AD pen already on you don't need it because Q scales right down the middle and the dash is the only one without an AD ratio and it's not a spell you use for damage so hybrid pen or just AD pen is more than fine.

Last Whisper technically is around the same level of usefulness as Black Cleaver in terms of armor shred but Corki already has built in armor shred and true damage on an auto attack based on his AD so Black Cleaver is slightly better for more effects and boosts while also letting him reduce armor with any of his physical damage.

All these items are perfectly functional certain setups (sorcerer's shoes still work because marksmans and mages have little to no scaling making the purchase of a Sheen very effective damage wise and Last Whisper is still more effective on a tank target.) you just have to know how you want your Corki.
