Angel of Destiny
Most lifegain payoffs ask you to convert a big life total into cards or tokens; this one converts it into an execution. The end-step clause is a hard kill: fifteen life above your starting total, and everyone this Angel attacked simply loses, no combat math, no toughness to punch through, no chump block that saves them. The rest of the card exists to feed that trigger. Double strike doubles every attack's life swing, and the symmetrical lifegain (you and the defending player both gaining the combat damage) is the sly part: gifting life to your opponent looks like a drawback until you notice their higher total does nothing to protect them from an alternate win condition that only checks your margin above starting life. The 2/6 body is built to survive to that end step rather than to close on damage. What makes the design coherent is that a flying, double-striking body already climbs toward fifteen extra life on its own, so the win condition and the engine that powers it live on the same card. That folds a two-piece lifegain combo (the payoff and the reservoir that fuels it) into a single attacker, so the card behaves as a finisher rather than a build-around: the kill lands on the same turn it connects, since the check fires at your end step the moment your life crosses the threshold. Attack, gain, win, all inside one turn.
