Grapple with Death

Golgari has always paid a small premium for coverage. Mono-black can destroy a creature at instant speed for a card and a mana; the moment you ask a removal spell to answer artifacts as well, the rate softens, and pushing it into two colors is the compromise that buys the flexibility. What this pays for is a target line that catches both halves of the board most decks lean on: the threat that ends the game and the mana rock or equipment that fuels it. The lifegain rider is deliberately trivial, one point, because it is not meant to swing races; it is the sweetener that turns a fair trade into a slightly-better-than-fair one and gives black-green attrition mirrors a marginal edge over the long game those decks are built to grind. The sorcery speed is the tax that keeps the flexibility honest: you cannot hold it up as a combat trick or a counterspell substitute, so the card commits to the proactive, curve-out plan its two colors already want to run. Catch-most destruction like this has always traded a keyword of restriction (sorcery speed here, an exile clause or a life cost elsewhere) for width of target: unglamorous removal that never headlines a set but quietly does the work every attrition deck needs done.
