dealt to target creature this turn. When damage
is prevented this way, surveil 2 (Look at the top
two cards of your library, then put any number of
them into your graveyard and the rest on the top of
your library in any order.)
Threshold — {g/u}, {t}: Investigate (Create a
colorless Clue artifact token with "{2}, Sacrifice this artifact: Draw a card." Activate this ability only
if seven or more cards are in your graveyard.)
