@RIot Deadman's plate, but no Trickster's Mirror?

The mirror gave a very cool, very useful, and very unique active, making supporting and jungling, not to mention lane-swapping, super fun and interesting. The plate gives damage and speed. Not very interesting. Useful, absolutely, but still. Riot, don't let this concept die. PLEASE tell me a champion with an ability like the mirror is in the works? A doppleganger, or a Changeling or something. TELL me Runeterra wouldn't be home to such a race.
