Dr Clearrunner, DSR Researcher

Whenever a nontoken artifact enters the
battlefield under your control, Investigate.
(To investigate, create a colorless Clue artifact
token with "{2}, Sacrifice this artifact: Draw a card.")
The persistent doctor traveled between the worlds, gathering ancient artifacts and old records of what
each of the worlds were like before the war. Maybe
one day she could find away to separate them once
again.
