Solfatara

A land-denial spell with an apology stapled to it. The core effect is a tempo tax: catch an opponent with a land in hand and that drop evaporates, stalling their curve for a turn. The replacement-draw rider is the design discipline at work, the concession that pure denial at this rate would be a dead card most of the time. By guaranteeing the card back at the next upkeep, Solfatara becomes a free cantrip in the worst case (when the target had no land to play anyway) and a small tempo swing in the best. Instant speed matters only in a narrow way here: because the restriction lasts just "this turn," the spell has to land before the opponent's main phase to deny anything, so the live window is their upkeep or draw step, not their end step where no land could be played regardless. Note too that it shuts down the special action of playing a land, not other ways lands reach the battlefield, so a fetchland or any effect that puts a land in via its own ability sails right past it. This is the era's recurring experiment with disruption that refunds itself, the same logic that lets a bounce or counter cantrip rather than card-disadvantage you into a hole. The trouble is that denying a single land drop rarely earns three mana, and the delayed draw leaves you down a card the turn you cast it. A clean idea about taxing development without trading down, executed at a rate that never quite justified the slot.
