Yorick is by far my most favourite champion. He is really fun to play and has a lot of potential. You can destroy a tower really fast with your ghouls and ultimate. Your ghouls can deal alot of dmg with the right items and even before you reach the enemy, your ghouls took alot of life from them. They are annoying too. Just be sure to hit your E so your ghouls will jump to the enemy and deal dmg on landing. You get bonus movement speed too if u run to the enemy that you hit. Theres a small tipp for yorick: if you can summon your ghouls, hit your E first and then summon your ghouls they will jump to the enemy so the enemy cant kill your ghouls before. The best role for yorick is top lane, cuz you need a few items for him to be strong cuz of the low mobility. Who doesnt want o destroy enemies with a shovel ! :D
