New Champion Suggestion

A friend and I had an idea for a new champion that would act as a "Tamer". Imagine a young boy that has tamed a wolf. I haven't thought much into the lore of it all but I have thought through some of the mechanics. The boy himself would not have any abilities. He would just be a squishy target that controlled the wolf who did all the fighting. The wolf would be a high damage, and mildly tanky melee fighter that would roam a small distance in front of the boy. If the wolf dies, the boy is helpless and has to return to base, so he would gain movement speed if this happened since he has no abilities himself. The actual death happens if the boy dies. Think of it as a mix between Annie and Kindred, with a twist. His Q could be a basic command that makes the wolf charge. The W could be a growl similar to Rengar. The E could be a defense buff for the wolf. The Ultimate I thought would be tricky to use. I was thinking the boy sacrifices health which send the wolf into a rage, dashing and attacking the nearest enemy with increased damage. Obviously this all needs to be thought out more, but I thought this could bring a new dynamic into the game since it would be tricky to keep the boy safe while effectively attacking with the wolf. Let me know what you all think :P
