Big Game Hunter

Spot removal that stalks the top of the curve: the destruction trigger only fires on a creature with power 4 or greater, which makes this a precision tool against the exact threats that out-size cheap interaction. The body it rides in on is incidental; the value is in the enters-the-battlefield clause and the regeneration-proof clause that follows it, which closes the door on anything that would otherwise crawl back. What sharpens the design is madness. Discard this to a rummage effect or a hand-size cut and you can cast it for a single black mana, turning a dead card in your hand into instant-speed assassination at the moment a fat creature resolves. That window is the whole point: ordinarily this is a sorcery-speed creature you have to commit to the board, but laundered through a discard outlet it answers a haymaker on the stack's heels, ambushing the opponent's biggest threat before they can attack with it. The power-4 gate is the restriction that keeps the rate fair: it does nothing to the small creatures most decks are built on, so the card only earns its keep against the heavy end of the board. It reads as a dedicated answer in creature form, a body you can also discard, and the madness cost is what bridges those two modes into one card that flexes between hardcast value and reactive removal.
