PROS:

+Strong at the beginning
+Its a good tank
+Can slow your enemies


CONS:

-Be assist at mid/late game
-Don't have spells to escape

I prefer this way, because if u top solo Omen of Famine can be a very effective way to heal yourself.
Omen of Pestilence is a good option for who is running out of the battle, the slow is good for escape or for catch runners.
Omen of War Is nice for more damage and movement speed.

FULL DPS

Best option because of yorick don't have escape ability so do it


I like this for run and for catch enemies.

I don't test another Spells but u can

A list u can do:

Manamune - Its very necessary in ealy game mid/late game u can sell it
Trinity Force - VERY EFFECTIVE garants some attack speed and ability power
Bloodthirster - ANOTHER GREAT OPTION gives some GREAT damage
Hextech Gunblade - Good for some more damage Q
Infinity Edge - A way to get more damage and critical
Phantom Dancer - I like it for some fast pishicals damages
Ionian Boots of Lucidity - best option for yorick no more to say

I can't do a 100% guide of tank, it depends of the enemy team
So lets start;

Against Xin Zhao Master Yi and more heroes that is ad you can do:
Thornmail
Guardian Angel
Warmog's Armor - great health you can do 2 if u need

Against Ziggs, Karthus and more heroes that is ap you can do:
Force of Nature
Quicksilver Sash
And others.

if the other team haves 3 ap, you'll do magic resist.
if the other team have 3 ad, you'll do more armor.
Both need heal so you can make Warmog's Armor first.

Early game:
Creep more you can, with w and e, if u solo top, take the enemies together and spell w and e to give some damage, this way u'll take them far and make money

Mid game:
Help your team in teamfights around the map, Q is very STRONG against some enemies, just do your game, FIRST W SECOND E AFTER Q, if necessary R.

Late game:
Yorick isn't a surprise in late game, so try to help your team and get more kills possible
