Heroes' Reunion

Seven life for two mana, with no caveat, no body left behind, no card drawn: pure life gain as a self-contained spell. That is a hard sell, and the card knows it. Lifegain without a payoff has always been the weakest thing an instant can do, because lifegain alone changes no board, answers no threat, and pressures no clock; it only buys time, and an opponent with cards left in hand is happy to sell you that time. Healing Salve, Stream of Life, and their descendants all wrestle with the same problem, and this one picks the most generous flat number it can offer and stops there. The flavor frames it as allies regrouping mid-battle, which is exactly the strategic role it fills: a panic button for a green-white deck losing a damage race, swinging seven points back in a single attack step or surviving one more burn spell. A deck wanting this effect almost always wants it attached to something (a creature, a draw, a permanent gaining lifelink) rather than spent as a naked instant. What keeps the card from total obscurity is the size of the number relative to the cost, which makes it occasionally useful in builds that treat raw life total as a resource to be banked and spent, rather than as a buffer that incidentally keeps you alive.
