Profane Tutor (Retro) [Modern Horizons 2]

Suspend 2—{1}{B} (Rather than cast this card from your hand, pay {1}{B} and exile it with two time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost.)
Search your library for a card, put that card into your hand, then shuffle.
