Nasus

Nasus isn't that hard of a matchup in laning phase. You can't really stop his farm so just try to harass him and farm as much as you can. I reccomend rushing executioner's as it will stop his healing a lot. Then upgrade to mortal reminder later. In teamfights just peel him off from your carries so he cant get that nasty q off.

Teemo

Teemo is a really annoying matchup for Yorick. You'll want to play more safe since his poke is very annoying. Start corrupting and I personally like to rush Adaptive helm. It really helps against his constant poison poke.

Camille

Camille isn't that great against Yorick. She can however, use her e to hop over your wall or back into you. If she engages and ults, you can usually win the fight with your ultimate if you are the same hp.

Renekton

Renekton is somewhat of a counter to Yorick. Hes a lane bully so he doesn't let you farm. Play safe and wait under tower to get cs. Start cloth armor and pots. Go all in when he makes a mistake or tries to tower dive you.

Pantheon

For me, Pantheon is one of the hardest matchups against Yorick. Play extremely safe and do not try to fight. His passive is really dumb which lets him block a tower shot to trade with you under tower. Just play safe, stack up armor, and wait for the late game.

Tryndamere

Tryndamere is another lane bully, which is hard for Yorick. In this matchup you should play safe and try to get your jungler to gank pre-6 so tryndamere cannot ult. After he has ult, do not fight him as Maiden of the mist is countered by his undying rage. Just grab a ton of armor and kite him when he tries to dive you.

Gangplank

Gangplank is really easy. Since GP has an extremely terrible early game, make use of it and kill him early. He has no way to get out of your dark procession unless he flashes. Once you get 6 try to all in him because he is still not that strong at that point. Late game try to focus him so he doesn't 1 shot your adc/mid.

Singed

Singed is probably the easiest matchup. If he proxies your wave at the start of the game, ignore him and let the enemy wave come to your tower and get the farm. Then if your jungler comes to gank singed while he's proxying, try to kill him with your dark procession since he literally has no way to get out of it since singed will probably run flash.
