TO GET TO THE POINT, SKIP TO SECOND PARAGRAPH
Rito has done a very good job of filling in the slots in champion element. What I mean by that is this: Every champion is unique in it's own way. We needed a champ to personify poison? Boom, Twitch. Fire? Brand. Stone? Malphite and the list goes on UNTIL you get to the undead. Yorick's role in League of Legends is not what it could be, and I'm pretty sure we can all agree with that. What I have wanted for a long time, is for the TRAINER element to be filled. We don't have any champs that exercise authority over another creature or creatures to do their bidding other than Yorick, and Lulu. I had a dream about a champion element that could "Train" it's subjects to fight for him. It could have multiple subjects that fight for him. They follow him and grow with him. Need a group of bodyguards? send a defensive command to the units and have them encircle you and grant bonus armor or something. Need an elite group of hitmen? Send an attack command to the units and have them aggro an enemy unit. Perhaps you need some quick vision but can't carve out the opportunity to check a brush.. Right click and send one of the units there to scout the area itself. Yorick's current abilities also give room for improvement. If he hits his opponent with a shovel, a ghoul shows up. Ghouls should strictly come out of the ground if these abilities are to be in line with his lore and champion element. In addition, Yorick should be able to control one or more ghouls like mordekaiser, only, the ghoul or ghouls have their own abilites during this control, such as dashing, slashing, and slowing.
This is how I think Yorick could fulfill his role. These are the changes I suggest:
-Ghouls appear STRICTLY out of the ground, or have some other association with the ground.
-One or more Ghouls can be controlled and given special abilities, perhaps like Kha'zix' ulti passive.
-Ghouls still lose life over time, but may be kept alive longer by attacking(Just like SION)
-The majority of Yorick's Power comes from his ghouls and therefore is not very strong without them present
-His ultimate shies away from being like Zilean's, in that it involves a ghoul army rising from the ground enacting revenge for their fallen king.
-Ghouls are leveled up as individuals, possessing some of Yorick's traits, yet branching out in their own uses.
-Yorick can walk over dead bodies of champs and 'salvage' in whole or in part, some of the champ to use for later in upgrades or combination ghouling.
-Yorick could have a legit dragon trainer skin, giving him mastery over feisty little dragons, and also SKYROCKETING the skin sales for dragon trainer. These are just some of the ideas.

are more poison then 
Commander of an army
Master of a demonic bear
Master of a killing machine
has specialize pet somewhat
would represent the opposite of Yorick, where yorick constantly send pet at you Heim has you come to his pet/units
