Nefarious Revelation

Kicker - {1}{b}, Sacrifice 2 Clue tokens, Pay 4 life
As an additional cost to cast Nefarious Revelation, sacrifice 3 Clue tokens.
Search your library and graveyard for any 3 cards, reveal them, and put them into your hand. If this spell was kicked, you may instead play any 3 cards from your hand, library, and/or graveyard without paying their mana costs. Either way, shuffle your library afterwards.
