Willow, Proprietor of Secrets

Informant —Whenever you investigate, you may
pay {1}. When you do, surveil 2. (Look at the top 2
cards of your library, then put any number of them
into your graveyard and the rest on top of your library
in any order.)
{t}, {u}{b}: Counter target spell, then each player investigates. (Create a colorless Clue artifact token
with "{2}, Sacrifice this artifact: Draw a card.")
