Unburial Rites

The split cost is the whole design. Hard-cast, it returns a creature for five mana the ordinary way: pay the black, get the body. But the flashback turns the card itself into the payload, reanimating from the graveyard for white mana without ever holding it in hand or paying the front-side cost. That white back end is the pivot. White is a primary reanimation color, yet it cannot fill its own graveyard; it has no looting, no self-mill, no rummaging. So the design hands the enabling work to the colors that do have it (blue, black, and red bin the fatty), and lets white pull the threat back on the cheap. The card is purely a payoff: a reanimation spell that wants to be discarded rather than drawn, which sidesteps the dead-draw fragility of every reanimation deck where the spell rots in hand while the creature sits in the library, or vice versa. A spell you would rather pitch than cast solves half that problem by design. The flashback's exile clause is the brake, capping each copy at one reanimation through the graveyard before it is gone, and keeping the card off the recursive-loop list. In the broader lineage it sits between the explosive two-card reanimation engines that need both halves assembled and the grindier value reanimation that wants its outlet in the bin. The white flashback is the specific innovation: a reanimation outlet living in colors and graveyards the spell's own casting cost could never reach.
