Underworld Wayfarer

Suspend 3 — {u/b} (Rather than cast this card from your hand, you may pay {u/b} and exile it with three 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.)
When Gravedigger enters the battlefield, you may return target creature card from your graveyard to your hand.
Aren't you the lucky one?
