Bonecaller Cleric

Reanimation folded into a body, which is the whole trick of the design. Buying a dead creature back usually costs a card and a slot; here the effect rides on a cheap beater you were already happy to run, so the recursion is deferred rather than dedicated. The sacrifice cost does the balancing: the Cleric spends itself to bring something bigger back, which means the two-mana body is a placeholder that converts into a fatty you discarded, a value creature that traded, or the key piece of a sacrificed token engine. Note that it cannot loop on itself: targets are locked in before you pay costs, so the creature it returns is always something else that predates it in the yard. It can of course be fed to an outside sacrifice outlet like any creature, though then it isn't paying its own reanimation cost; either way its departure still trips any passive death triggers a deck is running. The sorcery-speed clamp rules out instant-speed blink shenanigans and combat ambushes, and stacking a four-mana activation on top of the initial cost makes the full loop a real investment rather than a cheap engine. In a deck built around bodies entering and leaving the battlefield, the Cleric is both a participant and a redundancy: an extra copy of an effect black has spent its whole history charging a premium for. It asks nothing when it arrives and cashes out when it leaves.
