A 2/8 is the whole shape of this thing: a wall first, a payoff second. The enters trigger reads like a lifegain spell stapled onto a defender, but the structural cost is what makes it work. Tapping your own untapped creatures is not free; it pulls them out of an attack or, more pointedly, taps down would-be blockers right as a board is forming. The life swing scales with how wide you already are, while charging you the defensive utility of the very creatures you tap. The trigger explicitly wants untapped creatures, which is where the design quietly opens up: vigilance bodies, mana dorks sitting back, untap-for-value engines, anything you'd happily tap anyway turns the drawback into a wash and keeps the eight toughness standing guard regardless. It is a token-strategy lifegain anchor more than a midrange creature, asking you to convert a wide board into a one-time cushion the turn it lands. That conversion is the catch: the more bodies you funnel into the life total, the fewer you have left to block or swing with that turn, so the spike comes when you're already committed to the board. The Elemental typing and green's lifegain-through-mass identity place it in the lineage of payoff bodies that reward going wide rather than tall, with a butt large enough that the lifegain feels like insurance rather than the plan.
