Bandage

Damage prevention stripped to its smallest legal unit: one point, no scaling, no flexibility, and then a card draw bolted on so the spell replaces itself. The design logic is plain once you separate the two clauses. Prevention spells of this era ran a long gradient: some scaled with mana, some doubled as combat tricks, and most asked you to spend a whole card to stop a meaningful chunk of damage. This one refuses to scale at all. One point of prevention rarely changes a combat or saves a creature worth saving, so the ceiling is deliberately negligible and the floor sits right next to it. The draw is the entire reason the card exists; the prevention is decoration, a fig leaf of relevance pinned to an effect that is really just a one-mana cantrip in white's clothing. It answers a question the design was built around: how marginal can an effect be if it also draws a card on the way out? Blue got a run of one-mana cantrips with various trivial riders; white's version pairs the replacement draw with the most modest damage prevention the rules will allow. The result is a card you never have to think about, because there is almost nothing to think about: cast it when you want a card, and the prevention will occasionally matter by accident.
