Surveil lets you look at a number of cards from the top of your library and put any of them into your graveyard, leaving the rest on top in any order. It combines card selection with deliberate graveyard setup.
Disinformation Campaign rewards repeated surveilling, while Dimir Spybug grows whenever you surveil. The cycle of surveil lands, such as Undercity Sewers, makes the mechanic available directly from the mana base.
