Skeletal Scrying

Card advantage that costs you your fuel: every card you draw comes out of the graveyard, so the spell that refills your hand also strip-mines the resource a graveyard deck spends. Drawing X cards for is an absurd rate in isolation, but the exile cost and the life payment together keep it from running away. The life loss scales with the draw, punishing the greedy keep, and the exile cost competes directly with flashback, threshold, and recursion strategies that want those same cards staying put. There is a built-in contradiction here: the more cards in your bin, the more you can draw, but the deck best positioned to feed it is also the deck that least wants to empty its yard. It rewards the player who rations the graveyard rather than spending it freely, drawing exactly enough to find the answer without burning down the resources a black control shell leans on. The variable cost that doubles as payment and self-inflicted wound speaks to black's whole bargaining identity: power is always on the table, and the only question is what you are willing to spend to reach it. That double edge sets it apart from a flat refill like Ancestral Recall priced into black; here the graveyard pays the printing cost, and a deck has to decide which half of its plan it is willing to mortgage.
