Voices from the Void

Discard effects have always fought a clock: by the time five mana is online, the opponent has usually emptied the hand the spell was meant to strip. The domain scaling is the wager this card makes against that math. Cast off a single basic land type, it is the worst hand-disruption five mana can buy: a one-card discard with four wasted mana stapled to it. With all five types online, it strips a full grip in one swing. That ceiling is real but conditional, and the price of the condition is the manabase: domain rewards fixing you were probably not going to build for a black discard spell, which is precisely why the rate sits where it does. The effect counts basic land types among your lands, not basics themselves, so dual lands and fetchable shocklands feed the tally without diluting the deck into a five-color pile. The design lives in that tension between a spell that wants greedy fixing and a color that traditionally hoards its mana for itself. Sorcery-speed discard carries a structural ceiling no scaling can fix, since the opponent draws a fresh card every turn and any card struck on the back half is one they just replaced. The spell pays out best against a hand that is still full and a manabase that already touches every color: a deck stretched wide enough to fuel the domain count is the same deck that makes the five mana hurt, which is the bind the card never quite resolves.
