How to counter Vladmir

You could play Yasuo and give him HIV.

Honestly I'd say will be a good counter too.

He has plenty of blood to spare and if Vlad even tries to go all Dracula on him, he will get diabetes.

You can’t make a stone bleed. But a mountain?

Vacuum Cleaner whenever he pools

But what about the undead , spectral beings , trees , and death itself ?
