The reward structure is the part worth studying: the trigger fires whenever another green creature you control enters, but the counter lands on a creature you choose, not the creature that triggered it. That separation is what elevates the engine past a glorified anthem. You can stack every counter onto a single attacker until it becomes a finisher, or spread them to whatever needs the help. Each entering green body is one discrete counter, so the payoff scales with the cadence of new green creatures hitting the table: a deck that drip-feeds bodies turn after turn keeps the assembly line moving, while a deck of a few fat threats triggers it once or twice and stalls. The 2/3 body is deliberately modest because the card is sold as a payoff piece, not a beater: it needs to survive a turn and start the engine, not win combat on its own. It also chains with itself in a way that is easy to overlook, since the targeting clause lets it pad its own toughness when nothing better presents itself. This is a go-wide green incremental engine, the slow-rolling advantage piece that a token or creature-density build leans on to convert a stream of small bodies into a single unanswerable threat. The color check is the line that keeps it honest: the trigger reads green, so a multicolor Gruul or Selesnya creature still fuels it, but a splashed nongreen threat contributes nothing to the count.
