User blog comment:Fistful of Force/PSA: Trundle and Nasus DO NOT COUNTER YORICK/@comment-5266525-20120717135306/@comment-130.126.30.18-20120717173446

On page four in the thread, there is some math about how trundle's passive heals next to nothing because of the ghouls. In addition, while trundle may be able to steal Yorick's AD, he will not be able to out damage Yorick because all four of yorick's spells do more damage than trundle's, and Yorick flat out out sustains Trundle.

Nasus will run out of mana and be harassed out of lane or get towerdived by yorick.
