Cute.
Ikr, those are my top two counterpicks for her, but just imagine this, Yorick's level 6 all in is keeping them trapped as he summons The Maiden and forces 4-6 units all on his opponent, if she ults then that is exactly what Yorick wants, a small, crammed area that he can abuse and either she fights for her bonus damage or she backs off and you wasted her ult
Pretty late to this discussion, but I don't think Yorick really counter's Camille. She can kill him so fast his maiden is almost useless. While I have fought and destroyed a Camille as Yorick I've also fought several Yoricks as Camille and utterly wrecked them. Darius on the other hand, counters Camille pretty hard; though primarily in the early game. If she plays safe and doesn't feed him and manages to get kills on other opponents, she can take on Darius just fine.
