Gamekeeper

A combo enabler whose value comes entirely from what dies, not from what attacks. Send this Elf to the graveyard and it digs through your library, dropping the first creature it reveals straight onto the battlefield while everything passed along the way is buried. The shape of that dig is what governs the rate. Because it stops at the first creature card, the payoff scales inversely with your creature count: a library thin on bodies forces the reveal deeper, raising the floor on what you slam down, while a deck packed with creatures hands you whatever happens to sit near the top rather than the haymaker you wanted. The optional exile clause is the structural release valve. Reanimation strategies warp around the graveyard, and exiling this body pays the cost of triggering the dig while removing it as a future loop target, so the design keeps you from recurring the same enabler indefinitely. The friction lives in the timing: nothing happens until the body dies, so the deck has to supply a sacrifice outlet or accept that combat and removal will fire on someone else's schedule. Build it correctly, with a single oversized threat and a thin spread of creatures to find it, and the death trigger becomes a near-deterministic way to cheat that threat into play. Build it carelessly and you have a fragile 2/2 flipping whatever you stumble into.
