Grave Researcher // Reanimate - Extended Art [SOS-325]

At the beginning of your upkeep, surveil 1. Then if there are three or more creature cards in your graveyard, this creature becomes prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.) // Put target creature card from a graveyard onto the battlefield under your control. You lose life equal to that card's mana value.
