Cyber Bureau

At the beginning of your upkeep, investigate.
(Create a colorless Clue artifact token with "{2}, Sacrifice this artifact: Draw a card.")
Whenever you sacrifice a Clue token, create a 1/1 colorless Thopter artifact creature token with
flying and "Whenever Thopter attacks, surveil 1."
(Look at the top card of your library. You may put
that card into your graveyard.)
