Bog Down

Discard at three mana lands in the awkward middle of black's hand attack: too slow to disrupt early, too symmetrical with what the opponent's already drawn to gut a midgame. The kicker is where the design gets honest about that. Sacrificing two lands to force a third card from hand is a brutal trade in a vacuum, but it answers the specific late-game problem with two-for-one discard, which is that you've usually emptied your own hand by the time you cast it. Paying with permanents you no longer need turns a dead late draw into extra disruption. The math rarely flatters it: two lands and a card for three discarded cards is card-neutral at best, and you are the one whose mana base is now shorter. That tension between the desperation cost and the marginal payoff is what keeps Bog Down on the fringe rather than in the canon of black disruption. It belongs to the Invasion-block experiment with kicker as a deferred-cost lever, where the base spell is a floor and the kicker asks how much of your own board you'll dismantle to push a little further.
