Demonic Bargain

Every unconditional tutor pays for its power somehow, and this one names the steepest fee design has dared: it retrieves any card, no restriction on type or color, and exiles thirteen cards from your library to do it, with no way to get them back. That is not a downside so much as a threat. Thirteen cards is roughly an eighth of a hundred-card list and a fifth of a sixty-card deck, banished sight unseen. Vampiric Tutor and Demonic Tutor extract a small toll and move on; this one asks whether the single card you need is worth mortgaging the rest of your draws to find it. The exile clause makes the spell nearly unplayable in a grinding fair deck, which cannot afford to hemorrhage that much library, but it turns acceptable, even correct, in a build that only needs to reach the turn a specific card wins the game. If the tutored card ends things before those thirteen missing draws matter, the cost never comes due. It is a tutor priced for combo and nothing else, a deliberate statement that unconditional search is fine so long as the price walls it off from the fair decks that would grind the hardest with it.
