Doom Reigns Supreme

The Plan subtype builds two clocks off a single trigger and asks you to profit from both without needing either to arrive on schedule. Every Villain that hits the battlefield does the same two things: it drains a life in each direction, and it nudges a counter toward five. The drain is the floor, ticking up as long as your board keeps developing, so the enchantment is never dead while it waits. The exile-and-cast burst is the ceiling, and it fires exactly once: at the fifth counter the enchantment sacrifices itself, and there is no spending counters back down or resetting the meter. The trigger is entry, not death, which shapes the whole build around going wide with bodies that stay on the battlefield rather than feeding a sacrifice loop. Where the design turns pointed is the cast clause. Those two free spells come off the opponent's library, not yours, so the payoff folds their expensive answers and threats into your own tempo instead of adding raw cards to your side. That framing rewards a deck that can already close the game before the fifth counter lands and treats the heist as a finisher, not a lifeline: you are not digging for gas, you are stealing whatever the top of an opponent's deck happened to be hiding. The tension is honest. The steady drain keeps the card relevant on the way up; the delayed detonation only pays off a board that was winning anyway.
