Final Fortune

The original devil's bargain in the extra-turn line: two red mana buys a full turn, with the most absolute price the game knows how to charge. The "you lose the game" trigger is not a tax or a penalty you pay later; it is a deadline. This is the card that taught a generation of red players to think in lethal-or-bust terms, because the turn you take here has to be the turn you win. Everything after the trigger fires is irrelevant, which inverts how extra turns usually work: instead of compounding an advantage, this one demands you already have the kill assembled and just need one more attack step, one more burn spell, one more activation to close. The design honesty is what makes it interesting. Later extra-turn cards (Time Walk being the dream, Temporal Manipulation the fair version) all hedged the cost into mana or restrictions; this one put the whole bill on a single delayed clause and let the player decide whether the turn was worth dying for. It also seeded a tiny combo lineage: pair the loss trigger with anything that prevents you from losing or wins before the end step arrives, and the drawback evaporates. The card reads as a do-or-die gamble, but it functions as a switch, off by default, that a sufficiently clever board can flip to "free turn."
