Battlefield Scrounger
Most threshold cards treat the graveyard as a one-way switch: cross seven cards and the upside stays on. This one rents the boost back. The pump costs three cards from the graveyard, your choice of which, placed on the bottom of the library, which means every activation actively unbuilds the condition it relies on. Run it three turns straight and you have spent nine cards, eroding threshold from the inside unless you keep refilling. That self-cannibalizing tension defines the card: a recurring +3/+3 gated behind a resource, where using it taxes that same resource. The design asks you to run a graveyard engine deep enough to feed both the threshold check and the activation. The once-per-turn clause keeps it from snowballing in a single combat step, turning it into a slow grind tool rather than a burst finisher. As a five-mana 3/3, the static body is unremarkable; the appeal is a Centaur that can swing for six whenever you can afford to mill backward, and keep doing it as long as the bin stays stocked. This is threshold reimagined as a deckbuilding contract rather than free upside, and it is one of the more honest expressions of that idea: a payoff that makes you pay twice, once to turn it on and again every time you fire it.
