Both of those abilities are great, but you also get to put another counter on a permanent every time you cast a noncreature spell
Once you're done with that, it's time to decide what your deck's colors are
Birds of Paradise and Llanowar Elves may have the original rep as iconic green creatures, but modern design favors reprints of Sakura-Tribe Elder over one-mana dorks
Relic of Legends just keeps going, and Faeburrow Elder and Bloom Tender can tap for up to five, just like Jegantha, and Selvala, Heart of the Wilds
Jaheira, Friend of the Forest turns all of your tokens into mana dorks Treasure tokens included allowing you access to large amounts of green mana, pretty much how a strong druid in Dungeons & Dragons would in a similar context
You choose which creatures get counters after you roll the dice
