Tireless Missionaries

Five mana for a 2/3 and three life is a curve-filler rate, not a game-ending one, and that is honestly the whole brief. This is white's vanilla-plus baseline: a defensive body with an enters-the-battlefield rider that reads as a small consolation rather than a payoff. The three life is incidental to the combat math, not the reason to run the card; at this cost it rarely flips a race on its own, and there is little to build around beyond the generic "a creature entered" triggers any pool happens to contain, plus the modest pull of life-gain payoffs or blink effects that replay the rider. Its design ancestors run back through every modestly bodied Cleric with a life-gain clause, and its descendants keep arriving in much the same shape because the role itself never goes away: a creature whose job is to stand in front of an attacker and pad a life total while the bigger pieces do the work. The discipline in a card like this is in what it refuses to do. The life gain is small, fixed, and one-shot, so at this cost it is rarely worth looping; the durable body is inert, so it cannot threaten. That restraint is the point: an honest baseline, priced and statted to be exactly the steady floor that more ambitious designs get measured against.
