Mind RotdiscardBudget$0.08A very close black discard spell at the same mana cost, making an opponent discard two cards total instead of random plus chosen. It fills the same midgame hand-disruption role.
Hymn to Tourachdiscard$0.41Classic black discard that can strip two cards for only two mana, often stronger than Stupor because both cards are random. It serves the same disruptive hand-attack role.
Raven's Crimediscard$0.37A repeatable discard effect that can keep opposing hands empty over time. It is less bursty than Stupor, but plays a similar attrition role in black decks.
Davriel's WitheringdiscardA black discard-based tempo spell that pressures hands and can also interact with small creatures in a pinch. It fits similar low-cost black disruption shells.
Kitesail Freebooterdiscard$0.12Not a sorcery, but it fills a similar role by taking a nonland card from the opponent's hand temporarily. It is a budget-friendly disruptive option for black-based decks with splash support.
Duressdiscard$0.19A cheaper hand-disruption spell that hits the opponent's best noncreature, nonland card. It is narrower than Stupor but serves the same general proactive disruption plan.
DespisediscardBudget$0.10Another low-cost black hand disruption spell that targets creatures or planeswalkers. It is a narrower, cheaper alternative for decks wanting early interaction.
Mind Twistdiscard$32.90A powerful scalable discard spell that can remove multiple cards from a hand. It occupies the same broad role of black hand destruction, though at a much swingier power level.
