Grave Researcher // Reanimate

The clever half of this card is that the reanimation isn't stapled to the body: it's a spell the body earns the right to cast. The upkeep surveil pulls double duty, filling the graveyard toward the three-creature threshold while smoothing your draws, and once that yard is stocked the Troll becomes prepared and offers a copy of Reanimate on demand. That structure is why it doesn't read like the usual do-both permanent. You're not paying up front for a fragile reanimator that dies to a removal spell before it ever fires; you're deploying a 3/3 that threatens to convert into a graveyard payoff turn after turn, and the copy costs a single black mana on the turn you finally pull the trigger. The life loss scales to the target's mana value, so the ability rewards patience in one direction and punishes greed in the other: the fattest thing in your yard is also the one that hurts most to steal. Note the wording carefully. The sorcery half can target any graveyard, not just yours, which turns opposing kill spells and combat losses into your resource pipeline. The engine asks you to feed a graveyard, keep a body alive, and time the conversion for the turn when a single mana and a chunk of life buys the most board.
