New Champion Idea ( Selargar )

I was thinking about a new champion what is a tank and AD or something like that... Selargar the black jaguar, scream of jungle, Rengar cousin. When he was 6 years old, Rengar left him in the jungle but our little cat finds way to his new home Demacia . Near the walls of the city were a blacksmith workshop. One good man adopted him and raise as his own son. He taught him how to fight and how to shoot with a sword and musket and how to make armors ... And i need to think about the rest of the story, but i've an idea for his jokes dance taunt and his abilities .
