Lathiel, the Bounteous Dawn

Lifegain in green-white has usually been a passive resource: a number that ticks up and buys you turns, but rarely converts into pressure without a dedicated payoff stapled elsewhere. This design collapses that two-step into one legend. The end-step trigger reads life gained this turn as ammunition and spends it as +1/+1 counters, one per life gained, spread across your board; that reframes every lifelink attacker, every soul-warden effect, and every incidental gain into a permanent growth engine. The counters are the crucial choice: they land on other creatures, not on the Unicorn itself, so the payload is about widening a threat base rather than fattening one body. That pushes the deck toward going wide, where five or six life in a turn distributes into a board that outsizes what a single anthem would produce, and it plays cleanly with proliferate as a way to double-dip after the counters arrive. Because the count scales directly with the amount gained, a lifelink swing that lands for a dozen becomes a dozen counters looking for homes, which is why the trigger rewards front-loading life into the turn rather than trickling it across many. The 2/2 lifelink body is deliberately small: it is the ignition source, gaining just enough on the attack to prime the engine while the counters accumulate elsewhere. The point of building around it is that it turns lifegain from a defensive stat into a distributed clock, closing the gap between the archetype's durability and an actual win condition.
