The Great Henge

The nine-mana cost is a fiction the card never intends to pay. Everything hinges on that first clause: the discount scales off your biggest creature's power, so a green deck that has already resolved a fat body pays a fraction of the sticker price and often lands this a full turn or two ahead of schedule. That is the engineering trick, and everything after it is the payoff, the thing that makes green players nervous about their own draws for once. Every nontoken creature that follows grows and cantrips, folding card advantage, board development, and incidental lifegain into a single permanent that also taps for two green the moment it lands. Green ramp payoffs usually pick a lane: a mana rock, a card-draw engine, an anthem. This collapses three of them into one artifact and then discounts itself into play off the very thing the deck was already doing. The snowball rewards a board already ahead rather than rescuing one that is behind: the counter-and-cantrip trigger only fires when you keep committing more bodies, so it accelerates a lead instead of manufacturing one from nothing. Keying that trigger to nontoken creatures specifically is what quietly walls off the token-swarm builds that would otherwise abuse it. What is left is a payoff that asks the deck to commit to fat, real creatures and then pays that commitment back with interest.
