not just some silver bullet, but core to how the deck functions. 4c Loam is operating at a (slightly) higher mana curve than the rest of the format to gain the benefits that 2-3drops provide over their 1drop equivalents (I'm simplifying here). In order to not be 1 turn behind our opponents we want mana acceleration. The best card by far for this is Mox Diamond, as it doesn't cost us our third turn. The alternative to Mox is Green Sun's Zenith. DRS provides another piece of ramp making a larger percentage of our hands playable (without being a turn behind)
I had a friend who pretty stubbornly tested Scattered Grove (or another in the cycle). It was worse than a proper cycle land almost every time. The only real benefit is bumping up our red sources, which isn;t really a problem anyway.
The deck is not "solved" in the way that RUG delver was a solved deck, but there is a core. The reasons for inactivity are that some of the discussion now happens on the facebook group, but mostly that the deck does not have the playerbase needed to generate enough results for competing "stock lists" to gain momentum. That's my theory anyway. Either way, most players just pick a list that has shown results and there isn't a lot of effort to change.
I'd also caution you against non-green fetches in a base green deck with a basic forest and a Dryad Arbor.
