Il Dottore "The Doctor"

You may have The Doctor enter the battlefield
as a copy of any creature on the battlefield, except
it's an Illusion in addition to its other types and
it has "When this creature becomes the target of
any spell or ability, sacrifice it."
Dottore's unfettered research towards creating a god,
or elevating humans to the level of gods, left him
ostracized from mainstream society but paved the
way for him to become one of the most powerful
members of the Eleven Fatui Harbingers.
