Dark Triumph

Five mana for a +2/+0 team pump is a price almost no deck would pay, which is the point: the printed cost exists so the spell still does something when you cannot meet the alternative condition. Control a Swamp, though, and the real version unlocks, where a single sacrificed creature buys the whole sweep. That accounting (bodies as ammunition, a stalled board converted into a lethal swing) sits at the center of the black-magic economy this design era was building toward, the same instinct that later gave aristocrat shells their currency. The timing is where the wager lives: you sacrifice before combat resolves, so you are betting the attacker you feed is worth less than the +2/+0 spread across everyone still standing. Against a board you were already planning to empty, that math is nearly free in tempo terms; against a wide opposing assault you can talk yourself into trading away your own blocker to make the survivors hit harder, going one body narrower to go several points taller. The Swamp clause is a quiet color-pie tax, keeping the cheap version a black privilege rather than a generic splash, and the moment you leave a Swamp behind the card snaps back to its uninviting mana cost (which still wants black, so it is no off-color escape hatch). What looks like a sacrifice payoff is really a combat finisher in disguise, written for a deck that treats its own creatures as expendable ordnance and wants a closer that costs it nothing it was not already spending.
