Jirina, Dauntless General

A tribal payoff that pays out exactly once, and that self-destruct clause is the entire pitch. Human decks have never lacked lords or aggression; what they lacked was a way to punch a board-wipe or a targeted removal spell without folding. Jirina answers by turning her own body into insurance: crack her in response to a Wrath, and the rest of the team walks away hexproof and indestructible. The exchange is deliberately lopsided in a way that keeps it honest, since you spend a two-drop and a graveyard-hate ETB to protect everything else you have committed. The graveyard exile stapled to the front end is the tell that this is a two-color design serving two masters at once: the white-black identity wants incidental interaction with recursion and reanimation, so the enters-the-battlefield trigger does disruption work while the sacrifice ability does the protection work, and neither depends on the other. That split is what makes her more than a creature that dies on cue. She is a soldier built to be traded, valuable at the moment she leaves play rather than while she sits on the board, which inverts the usual math on whether keeping a creature alive is correct. The reward is timing: the protection fires at instant speed off the sacrifice, so the window belongs to the Human player, not the sweeper's caster.
