Left Eye Kamui is long range and will only teleport a target.

Solid theory. IMO I would say Tenseigan is a Kekkei Mora but I guess it needs to be the first to count?(i.e. it would have to come before the Byakugan). This probably didn't happen because of the Rinnegan making up for it. They seem to be 2 sides of the same coin.
