I've noticed that i wrote "He has no phisical damage so black cleaver is not useful.", i've forgot to add "abilities" after "damage".

Last wisperer will garant you 35% armor penetration + 40 ad on every autoattack you will do. Kog has only magic damages on abilities, so noone of them will apply Black Cleaver stacks. So, you will have to do 5 autoattacks for get a 25% armor REDUCTION on the 6th attack. Meanwhile, half of your w duration is gone and your autoattacks will have on the enemy 10% more armor to consider.

With this, I confirm that Black Cleaver is complitely unuseful on Kog:

- He has to benefit the most amor penetration in the lower time possible as the moment that Kog is actually more useful than other carries on late game is during ult, and placing stacks for get a lower ignore on armor it's antiproductive;

- He has no phisical damage abilities, that means you will shred only the armor of your target with autoattacks, you're not a draven that uses ult and e for apply stacks on an entire team. If you're thinking about runan, things doesn't change a lot;

- You surely don't buy Black Cleaver for the health bonus, as 200 is quite irrilevant without resistances, also the 10% cdr may be useful but it's not enough for give an effective reduction on abilities (even if you don't need it on your ult, it's just for your w as adc);

- I don't get your argument "What will Last Whisper do? Give you more armor penetration for your magic damage W and Q?" as not even armor reduction and flat armor penetration will benefit your magic damage; I find it even more an argoment against buying Black Cleaver on Kog because, as I've said before, abilities deals magic damage (R does magic damage too), so you can't use them for apply its stacks that at the end will comes out as a lower amor shred than Last Wisperer's one.

TL;DR: you need full amor pen immediatly for fully benefit of your w range, so black cleaver is not effective on him.
