Faceless One

Before the game starts, search your library for a
nonlegendary creature card and exile it with a
face counter on it. As long as that card has a face
counter on it, it may not be removed from exile
and Faceless One is a copy of it, except it's
name is Faceless One, it's legendary, and it still
has its color identity.
Be careful or you may end up finding yourself on a
wall.
