Final Punishment

A finisher that converts work already done into a kill, and does nothing on a turn where no damage has landed. The trick is the wording: any damage a player has taken this turn becomes life loss, which slips past damage prevention and most lifegain triggers entirely. Stack a single large swing or a flurry of burn into the same turn, and a partial commitment doubles into lethal without rolling another attack or recasting another spell. The design lives or dies on setup; cast it after a quiet turn and it whiffs, which is why it wants high-damage one-shots rather than incremental beatdown. At five mana it is a top-end payoff, not a tempo play: you spend a full turn to convert damage you have already invested, so it rewards decks that can front-load a big hit before this resolves. The interesting part is the color it lives in. Black almost never gets to behave as a burn color, and fewer cards still let it punish damage rather than deal it. The clause that keeps it from being a slow-grind tool is the same-turn restriction: nothing banks, nothing carries over, so the card cannot reward patience. It is a reward for explosive turns, not a substitute for them.
