well im just a guy who liked the new yorick im not very good at the game but i think i found a gem here. my main acc is in plat 5 im a vayne main and i have been playing league for 3 years now. my summoner is sahiloisgoods but i mainley play on smurfs with friends.

yorick is very simple u can start on red or blue side i like blue more cuz mana sustain and cdr.
start tell your top to drag gromp a bit closer to blue so u can user ur Q and summon 4 ghosts after blue and go to wolfs quickly. TIP if u mess up and ur Q is in cdr take a few more hits and kill it with Q u want those mist walkers do this for all camps if u dont have 3 walkers.

after you clear and your near 6 u hit a big spike. at 6 yorick ult is a very good tool to use to coutner jg yes counter jungle if u summon it in the jg it will follow u like tibbers and supply u with endless mistwalkers as u clear camps so as soon as u hit 6 and maybe have ur jg item go invade if he trying to fight u use E on him then W and just kill him dont be afraid to 2 vs 1 if u need to as your a monster wiht your ult with u.

mid to alte game is where you become useless if u cant stick on the enemy's back line generaly what u want to do is coutner jg alot and send ur R to split and u split with it or help your team or split a diff lane.

u can take redsmtie it makes it alot easier to invade people like kha and lee but blue is needed if you plan to teamfight pls try replacing items and tell me how it goes and if it works or not.
