Mire's Toll

Targeted discard has always paid a price for the privilege of choosing the card. Thoughtseize charges life, Inquisition of Kozilek limits itself to cheap targets, Coercion costs an extra mana for the freedom to take anything. The toll here is structural rather than fixed: the spell scales the number of cards revealed to your Swamp count, so a single-mana sorcery on turn one shows you one card and scales toward genuine hand-shredding only after you have committed land to a heavy black manabase. That coupling makes it a strange thing among discard spells: a one-drop whose ceiling is gated not by life total or converted mana cost but by board development, which means it is weakest exactly when discard matters most (early, against a full grip) and strongest in the midgame when the opponent has already deployed half their hand. The reveal-and-choose structure is the discriminating discard you want, but the Swamp requirement quietly walls it off from any deck splashing black or running duals and shocks that do not read as Swamps. It is a reward for the mono-black purist: a cheap, precise hand-attack that only earns its precision if you have built the manabase to feed it.
