Revitalize

The "lifegain plus replacement" template, executed at the rate white has historically been allowed to charge for it. Two mana to draw a card costs more in white than in blue, and the gap is paid in life: the three points stapled here are the sweetener that justifies the effect sitting in white at all rather than shifting across the color pie. It is functionally the white cousin of an effect like Sign in Blood, except the life moves the right direction and the card count is one instead of two, which tells you exactly how the two colors are priced against each other. Instant speed is the quiet part doing the real work: it folds the lifegain into a combat or end-step decision rather than locking it to your main phase, so the buffer arrives when you actually want to know whether to take a hit or hold up a trick. There is nothing surprising on the card, and that is the point. It exists for the shells that want life-total movement to matter, dedicated lifegain builds counting triggers and grindy control decks that would rather trade a card for three points and a cantrip than sit dead in hand. It is a poor fit for aggression, where two mana and zero board presence is a tempo loss the beatdown plan cannot afford. A workmanlike piece of the white cantrip lineage, sized so it never warps anything.
