Angelic Accord

The four-life threshold is the entire design problem, and it is what turns this enchantment into a deckbuilding prompt rather than a payoff that fires on its own. Lifegain in white has always been plentiful and usually pointless: gaining four off a Healing Salve or a soul-warden trickle does nothing toward winning. This converts that wasted resource into a clock, demanding a board that crosses four life in a single turn, then rewarding it at the end step with a 4/4 flier. The friction is in the word "if": the check happens once per end step against a hard number, so incidental gains of one and two stack toward nothing unless you can bunch them into a single turn. The token itself only flies, so the Angel is a body and a beater, not a self-fueling engine; the lifegain that feeds the next trigger has to come from elsewhere, which is why this wants lifelink attackers, repeatable bursts, or Soul Sisters effects gone wide rather than a single Angel doing the work alone. That separates the decks that abuse this from the ones that merely run it and watch it sit idle. Among the enchantments that spin a normally inert quantity into a recurring creature spigot, few ask for so little ceremony: no activation cost, no mana, just a number you either reach in a turn or you don't.
