Consider (TLE)

Instant

Surveil 1. (Look at the top card of your library. You may put it into your graveyard.) Draw a card.

Key card draw engine for blue control and graveyard strategies. Consider packs efficient selection into card advantage—surveil smooths your draws while filling the graveyard for flashback, delve, and self-mill synergies. At one blue mana, it's a format staple in Pioneer and Modern control, and a reliable utility piece in Commander decks that benefit from library manipulation.
