Assemble the Entmoot

The payoff clause is a bet on a specific engine: not durdle lifegain, but a single explosive turn where the life you bank converts directly into board presence. The tokens arrive tapped, so this is not a combat trick or an ambush; it is a haymaker played before the crucial turn, a threat you assemble in advance and unleash on your own terms. What makes the design worth studying is how it stacks its two green virtues. The static reach line is quiet insurance that keeps your creatures relevant against fliers while the enchantment sits waiting, and the sacrifice mode rewards a lifegain deck for having gained a lot of life in one window rather than a trickle across many turns: three tokens sized to a single turn's gain, then reach counters bolted onto each so the Treefolk it makes carry the same anti-flying utility the enchantment was already granting. The X is measured per turn, not cumulative, which is the constraint that shapes the whole build: it wants a burst engine (a big lifelink swing, a one-shot drain, a Soul Warden trigger cascade) rather than incremental gain, because two life saved from three separate turns produces nothing. It reads as a green lifegain finisher, but structurally it is closer to a delayed token bomb whose fuel just happens to be measured in life points.
