Mecha or Battle cast Sion (CHOO CHOO)

I've played a lot of Sion and his ults is one of the funnest in the game even though it might not be the strongest. If league wants to make the most money out of any skin its Mecha or Battlecast Sion. He would be a robot and all but the main feature is that when he ults he turns into a train or somthing like that. As it is already the funnest ult it will be the coolest. Just imagine running down the mid lane as a train etc. CHOOO CHOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOooooo

Rito plz, if you wana make mad dolla bills yall you know what to do
