Merction, the Reliever

The concept of this champ is somewhat like Yorick, using minions/monsters for his own doings. The thing that separates his from other "mob users" is how he can "use" the mob. He has many different forms like Udyr in his monsters. He is also called "the Reliever" since he makes the Rift minions to his own, later creating an army that stacks. The forms that he takes in to his monsters can somewhat be close to a "type" in the series, Pokemon. His army/stacks are stored until he uses it. He has a maximum capacity that will be > 7 since this is just an idea. This can be his passive and will gain benefits the more diverse his party is, or the variety of types he has. His ult, consists of two options for which can be decided for I don't know what to choose from, going from ad/ap depended on the type he has more of, he sends all of his desired types into a cone, snaring and applying damage over time to all opposing units in the area for 1.5 seconds. The second option is he turns into one of his mobs but as a more stronger/faster etc. move set. His move set is changed depending on the type but the ult is a return cast, like Quinn. This is just an idea I wanted to get out, you guys can give ur feedback on the name, skill required, changes, and everything about this since this is just an idea. This may never be a champ in the League of Legends yet I can see a champion like Merction. Thanks!
