Warwick eats yorick alive. I have them both. Ive been on both sides of this situation many time. WW always wins

I just played a ranked with Lee Sin and i cant say he really counters Yorick. I won the lane but it was pretty much even. I think that ww would actually win just because of his outstanding sustain but not many lanewicks are out there anymore.

Big counters to Yorick because his ghouls basically feed him:
Tryndamere: Ghoul comes close --> more rage ---> more heals and or crits
Nasus: Q will get the bonus dmg if it kills the ghoul ----> feeding Q ----> 1 shotting people wait WHAT?
Trundle: Pretty sure his passive works with the ghouls too
Cho'gath: Same, pretty sure passive works with ghouls dying
So, basically all the champs that get power with killing stuff are good against Yorick. Nasus and Trynd are considered the "hard counters" to Yorick, but tbh he isn't truly hard countered by anyone. Those champs just have a lot easier time against him.
