Random champ idea, a general

In the vein of charisma based D&D classes, the champ would be able to burn mana/energy to take control of minions. One cost to influence a minion, another to move one (or a group) of minions around. They could use this to deny valuable CS, freeze lanes, steal enemy minions to fight for them, or even to stack a wave in a lane that's pushing. Not sure what would come of the rest of the kit but they scream "support!" in my mind, probably something for move speed like sona's (but for minions too?) or even an ability that momentarily prevents a champion from damaging minions.

As ults go, my gut would be to say "shaco split an entire minion wave" but that may be insane
