Intrepid Archaeologist

As long as a historic card is in your graveyard,
Intrepid Archaeologist can't be blocked.
Restore — Whenever Intrepid Archaeologist
deals combat damage to a player, exile up to one
target historic card from your graveyard. When
you do, investigate. (Create a colorless Clue artifact
token with "{2}, Sacrifice this artifact: Draw a card.")
