Kulothar, Formless One

You may have Kulothar, Formless One enter
the battlefield as a copy of any target permanent except it is blue and black, is a
6/6 creature, and has "{2}{u}{b}: Exile this creature, then return it to the battlefield
under your control"
It has worn every face you can think of, and
many, many more than that, yet it has no face
of it's own
