Youmuu's Ghostblade + Black Cleaver?

How do you counter the + combination? Over the last month, I've seen a ton of ADCs, AD mids, and carry top/junglers with this combination and often two or more champions on the other team (often paired with and/or ) have this combination.

Is a good counter? I would think so but many of these champions have life steal to negate the passive and you still need to buy additional health to make it effective. seems so-so since a lot of champions with this combo might not utilize crit or attack speed. seems so-so too since the Youmuu's active and Black Cleaver's rage passive give a good speed boost.

Any suggestions?
