Fecund Greenshell

This is two payoffs stacked on the same body, aimed at two different deckbuilding urges that rarely share a shell. The land-count clause rewards greed: pass ten lands and the whole board swings up, which is the ramp player's dividend for going long. The card-advantage engine rewards a shape most green decks never think about, a toughness-heavier-than-power creature. That second trigger is the more distinctive piece of design, because it prices in a body type green usually treats as filler and turns it into free card selection that fixes your land drops on the way to the ten-land threshold it needs. The 4/6 statline is not incidental: it satisfies its own toughness clause, so it triggers on the turn it lands and validates a build full of blockers and walls that would otherwise contribute nothing to a green curve. Reach is the small honest tax, keeping a defensive creature honestly defensive rather than an evasive threat. What makes it cohere is the loop between the two abilities: the enters-the-battlefield digging accelerates you toward the land count that flips the anthem, and every high-toughness creature you deploy to trigger the dig also gets fatter once the anthem is online. It is a green midrange engine that asks you to build around a body shape, then pays you in exactly the resource (lands into play, cards in hand) that a build-around usually spends itself dry finding.
