a possible new champion idea maybe?

i was walking to the store when for some random reason i thought about omen you know that one champ that turned into rek'sai well the name got me thinking what if omen was a witch doctor you know with the curses and the voodoo dolls that would make for a neat idea for a champion he could make for a neat support or a jungler that makes deals with the creatures(bonus he could be ivern's rival or something) there are a lot of possibilities with the witch doctor archetype so if any rioter reads this i hope i gave you guys a good idea
